Solar Sector Boundary Crossing


     A solar sector boundary crossing (polarity of the IMF reverses) indicated by ACE data has been responsible for the unsettled geomagnetic field. A high latitude Aurora Watch will be in effect over the next 24-48 hours. A favorably positioned negative polarity coronal hole is expected to continue to keep our geomagnetic field unsettled through March 29, 2011 UTC.  Old Sunspot Region 1429 is expected to return to the solar disk midday on  March 29th which should increase M-class flare probabilities.

     SOHO LASCO observed a full asymmetric halo CME on the 26th @ 23:12 UTC which was associated with Type II & Type IV radio sweeps.  This CME was determined to be a backsided event according to NOAA and not expected to be geoeffective.

      Although there was a large Sf and CME from old Sunspot Region 1429 that contributed to this halo CME there was also a filament eruption from the NE limb immediatly after, followed by a C5.3 flare the 27th @ 02:50 UTC with an associated CME (seen on SDO) from Sunspot Region  1444.  We expect this latter CME to be geoeffective.

     Here on the left we can see a CME associated with the C5.3 Sf from Sunspot Region 1444 as seen from SDO AIA 304 on March 27th at 2:57UTC.

Sunspot 1444 Growing Fast



  We are seeing some rapid growth today within Sunspot Rregion 1444 located in the northeast region of the solar disk. Region 1444 is yet another reversed polarity sunspot located in the northern hemisphere of the solar disk. We are watching this Region for continued growth as it moves into a more Earth facing position.



  
   The last reversed polarity sunspot we saw was Sunspot Region 1429 (also located in the northern hemisphere) that started its earth facing activity with a M3.3 flare on March 2, 2012 . To the left, we can see old Region 1429 as it appears on the STEREO Behind EUVI 195 image from today. 1429 has survived its transit on the backside of the Sun, and should be coming back into an Earth facing position around March 28th-30th.

M1.0 Flare With GOES 15 Back Online


   GOES 15 is working again as of 16:00 UTC today. Just a few hours into the Xray monitor being back in business, we have a "registered" M1.0 flare peaking at 19:40 UTC. This solar flare came from old sunspot region 1431 as it rotates back into a earth facing direction in the far southeast limb.

2012-03-23 16:50 UTC  SWPC GOES Data Again Available- Just in: GOES 15 xray, particle and magnetometer data are now again accessible as of about 1600 UTC (noon EDT) today. Imagery should be available again at approximately 1900 UTC.
 
It's anyones guess on how many larger flares we have missed while the monitor was down.

Solar Activity Update - CME Impact + M1.8 Flare


   At 13:40 UTC March 15th a geomagnetic sudden impulse was detected indicating that the CME we were expecting today has arrived. This CME was produced in association with a M7.9 solar flare from Sunspot Region 1429 on March 13, 2012. Solar winds reaching as high as 770.5 km/s and a proton density as high as 4.7 p/cc have been picked up at the ACE satellite. With the high wind speed and the Bz tilted south (-) this CME impact is stiring up a G1-Kp5 geomagnetic storm at this time.

Strong M7.9 Flare from Region 1429 - March 13, 2012


   A strong LDE Solar Flare of M7.9 peaking at 17:41 UTC has occurred around Sunspot Region 1429. There has been a slow drop in the Xray flux, indicating that there was a CME produced in association with this flare.
Update: there was a CME produced in association with this flare, see below for details.

Check back often for further updates and alerts on this event.
All updates will be added to the bottom of this report.


   Region 1429 on 60o - 70o longitude right now. With this CME that was produced today from 1429, this degree of longitude could cause a connection between the CME and Earth. Read all about this 60o west longitude connection here
http://science.nasa.gov/science-news/science-at-nasa/2005/10jun_newstorm/

   Here was can see there was a sharp rise in the proton flux immediately following the M7.9 Flare. This is another indication of a CME produced in association with this flare event




     The UMA proton flux forecaster model shown here to the left indicates that Earth is currently magnetically connected to Sunspot Region 1429, and that a SEP event is in progress.  This system is able to predict the onset and intensity of the first hours of well connected Solar Proton (SEP) events.  This forecaster identifies if there is a magnetic connection between the associated flare and the Earth, by correlating X-ray and differential proton data at 1 AU.

CME Arrival from March 10th M8.4 Solar Flare

   The CME associated with the March 10, 2012 M8.4 solar flare has arrived. At 08:54 UTC ACE detected the shock of the incoming CME. The SWPC originally forcasted the arrival time of this CME March 12th around 1800 UTC.  At this time the CME impact is stirring up a  G2 (moderate) geomagnetic storm. Conditions are expected to continue through today as the bulk of the CME passed Earth as the bulk of the CME passes Earth.  Solar wind speeds have been recorded as high as 774.8 km/sec and Density as high as 51.9 protons/cm

Update 18:14 UTC March 12, 2012:
There seams to be a fair amount of confusion floating around about the last 2 CME arrivals. Are they the two we have been expecting? Why are they not arriving when forecasted to arrive? Are we still expecting the CME associated with the March 10, 2012 M8.4 flare? We have put together the following in an attempt to help make the answers to these questions a bit more clear.

We are confident that on March 11, 2012 we saw the arrival of the 1st expected CME produced on March 9, 2012 in association with the M6.3 solar flare.
We are also confidant we are now seeing the arrival of the CME produced on March 10, 2012 in association with the M8.4 solar flare.
We base this on the ejection time & ejection speed of both CME's, as well as the Goddard Space Weather Lab CME arrival forecast that is posted directly after the events.

The March 9th M6.3 Flare + CME:
-estimated ejection speed of 750 km/s
-expected arrival time for the CME is on March 11, 2012 around 06:49UTC (+ or - 7hrs.)
-time we saw arrival - March 11 2012, at 11:59 UTC
http://mysolaralerts.blogspot.com/2012/03/cme-arrival-from-march-9th-m63-solar.html
(5hrs after the estimated arrival time,  there was a +/- of 7hrs on this CME arrival. This CME arrived within the expected arrival window)

-Spaceweather report on this CME arrival:
"CME IMPACT (MORE TO COME): An interplanetary shock wave buffeted Earth's magnetic field on March 11th at 11:59 UT. It was probably the first of two CMEs expected to arrive today."
http://spaceweather.com/archive.php?view=1&day=11&month=03&year=2012


The March 10th M8.4 Flare + CME:
-estimated ejection speed between 1200 - 1400 km/s.
-expected arrival time for the CME is on March 12, 2012 around 18:00UTC (+ or - 6hrs.)
-time we saw arrival - March 12 2012, at 08:54 UTC
http://mysolaralerts.blogspot.com/2012/03/cme-arrival-from-march-10th-m83-solar.html
(9hrs before the estimated arrival time, there was a +/- of 7hrs on this CME arrival. This CME arrived 2hrs before the expected arrival window)

-Spaceweather report on this CME arrival:
"WEEKEND SOLAR FLARE: Sunspot AR1429 is still erupting this weekend. On Saturday, March 10th, it produced a powerful M8-class flare that almost crossed the threshold into X-territory."
"In addition, the explosion propelled yet another CME toward Earth. According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the cloud will hit our planet's magnetosphere on March 12th at 1803 UT (+/- 7 hr), possibly sparking a new round of geomagnetic storms."
http://spaceweather.com/archive.php?view=1&day=11&month=03&year=2012
GEOMAGNETIC STORM UNDERWAY: A moderate G2-class geomagnetic storm is underway following the arrival of a CME on March 12th at ~0930 UT.
http://spaceweather.com/archive.php?view=1&day=12&month=03&year=2012


Update 18:09 UTC March 12, 2012:
Solar winds are remaining in the 700km/sec range. With the Bz remaining in the positive range this is keeping the Kp index at a Kp6 (a G2 geomagnetic storm). If the Bz turns south into a negative range with the solar winds remaining at over the 700km/sec range, a G3 storm could be produced. We will keep monitoring this situation and report any significant changes.

M8.4 LDE Solar Flare at Sunspot Region 1429 - March 10, 2012


   A strong M8.4 LDE solar flare has occurred at sunspot region 1429. The M8.4 flare peaked at 17:27 UTC and remained at that range until 17:44 UTC when we started to see a very slow drop. There was a bright CME (Coronal Mass Ejection) produced in association with this M8.4 flare.
This CME is Earth directed. According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the cloud will hit our planet's magnetosphere on March 12th at 1803 UT (+/- 7 hr)


The latest updates as well as alerts and warnings will be posted directly below so be sure to check back often.

   This M8.4 LDE flare occurred just under 2 hours after we saw a C8.0 flare peaking at 15:52 UTC from sunspot region 1430. There was also a CME seen produced in association with this C8.0 flare.This makes 2 CME's that were ejected today in Earths direction. More on this to come. Check back soon



  
   The Earth directed bright CME (Coronal Mass Ejection) that was associated with today's M8.4 flare as seen today on STEREO A



Update 22:11 UTC March 10, 2012:
From SWPC:
Analysis of Solar Active Regions and Activity from  09/2100Z
to 10/2100Z:  Solar activity was high.  Region 1430 (N21W42) produced
a C8 flare at 10/1552Z and Region 1429 (N18W26) produced a long
duration M8 flare at 10/1744Z with an associated Tenflare (459 sfu)
and a Type IV radio sweep.  Both flares had associated CMEs.  The
first CME appeared in SOHO/LASCO C2 imagery at 10/1624Z with
the majority of the ejecta off the NW limb.  The second CME,
associated with the M8 flare, first appeared in C2 imagery at
10/1800Z.  Further analysis will be done as imagery becomes
available, however initial analysis indicated the event produced a
full-halo CME with an estimated plane-of-sky speed between 1200 -
1400 km/s.  Region 1429 remained a large Ekc spot class with a
Beta-Gamma-Delta magnetic class.  A new region appeared on the ENE
limb near Region 1432 (N16E52).  Close proximity to the limb made a
detailed analysis of this new region difficult.

Update 22:11 UTC March 10, 2012:
From Spaceweather
WEEKEND SOLAR FLARE: Sunspot AR1429 is still erupting this weekend. On Saturday, March 10th, it produced a powerful M8-class flare that almost crossed the threshold into X-territory. In New Mexico, amateur radio astronomer Thomas Ashcraft recorded a series of shortwave bursts emanating from the blast site: audio. Also, the explosion propelled yet another CME toward Earth: forecast track. The cloud is expected to hit our planet's magnetosphere on March 12th around 1800 UT. A CME from an earlier explosion will arrive much sooner, however. Continue reading.....
INCOMING CME: A CME from sunspot AR1429 is nearing Earth. According to analysts at the Goddard Space Weather Lab, the cloud will arrive on March 11th at 0649 UT (+/- 7 hr). NOAA forecasters say the odds of a strong geomagnetic storm at that time is 50%

Update 20:02 UTC March 10, 2012:
*The M8.4 flare that started at 17:22 UTC today has now fallen to the C9 range @ 20:02 UTC, 2hrs 40min after it began.

M6.3 Flare + Earth Directed CME - March 9, 2012


   Sunspot Region 1429 has produced a  M6.3 solar flare at 03:22 UTC March 9, 2012. There was a Earth directed CME produced in association with this flare event. With a estimated ejection speed of  750 km/s the expected arrival time for the CME is on March 11, 2012 around 06:49UTC (+ or - 6hrs.)
We will update the details of this expected CME as more data becomes available.
Today there remains a strong chance for continued major flaring. NOAA has a 40% chance of an X-class solar flare today from sunspot region 1429.

Be sure to check back often for further updates on this event.
All updates will be added to the bottom of this report



   Here we can see the Earth directed CME as it appears on STEREO B

From NASA:
Event Issue Date: 2012-03-09 16:39:27.0 GMT

Arival Time Confidence Level: ± 6 hours
Disturbance Duration: 10 hours
Disturbance Duration Confidence Level: ± 8 hours
Magnetopause Standoff Distance: 5.2 Re


   From solen:
Region 11429 [N17E03] lost penumbral area with the main penumbra fragmenting into smaller penumbrae. The region still has several magnetic delta structures and could produce further major flares. The region was the source of a long duration major M6.3 event peaking at 03:53 UTC on March 9. STEREO-B indicates that another full halo CME was produced by this event.
One magnetic delta structure was gone in region 11429 after the LDE and the center of the region is becoming quite open. Several new ARs had spots at 10:00 UTC, see the most recent high resolution CHARMAP. S1517 was located at S23E33, S1518 at S26E23 while S1519 was at N06W25. AR 11431 has developed slowly today, and there is spot development in the southern part of region 1428 as well.

From SDIC:
Due to the position of the CME source region close to the solar central meridian, we expect a nearly central encounter of the resulting ICME, which will probably be a magnetic cloud with leading southward field. A strong geomagnetic storm (K = 7 or higher) is probable.

March 7th CME arrives after X 5.4 Solar Flare


   On March 7, 2012 Sunspot Region 1429 unleashed a X5.4 Solar Flare, Long Duration Event (LDE).  This X5.4 Solar Flare was associated with a type II and a type IV radio burst as well as a full halo, Coronal Mass Ejection (CME).  According to NASA the CME had an estimated plane of sky speed of 2200 km/s. The Interplanetary Shock of this CME arrived at the ACE spacecraft at 10:45 UTC signaling its immediate approach to Earth. 
We will be monitoring  the situation today as NOAA has forcast strong to severe geomagnetic storming while this CME interacts with Earth's magnetosphere.

The latest updates as well as alerts and warnings will be posted directly below so be sure to check back often.

Solar Radiation Storm in Progress

    Updated @ 17:24 UT March 7, 2012

     A SEP event is underway. We have become magnetically conected to Sunspot Region 1429.  At the time of this original post the 10MeV Integral Flux has exceeded 100pfu.
 NOAA Scale: S2 - Moderate
Potential Impacts: Radiation - Passengers and crew in high latitude, high altitude flights may experience small, increased radiation exposures.
Spacecraft - Infrequent single-event upsets to satellites are possible.
Radio - Small effects on polar HF (high frequency) propagation resulting in fades at lower frequencies.. Additional flaring from region 1429 will rapidly increase this proton flux.  When our "foot point" location, the area that we are magnetically conected to the Sun at becomes located at or very near an active region the connection allows Solar Energetic Particles such as protons and electrons to travel an extremely fast and direct path to Earth during a Solar Flare from that region. These Solar Energetic Particles travel at approximately 80% the speed of light and start bombarding the Ionosphere, within a few hours of a Solar Flare.  Additionally, during these events, CME driven shocks contribute to accelerating these particles. This Event was precipitated by the X 5.4 flare released early March 7, 2012 at  00:40 UT from Sunspot Region 1429.

    Here we can see the proximity of Earths "Foot Point" location to Sunspot Region 1429  just prior to the X 5.4 Solar Flare. Given this interplanetary magnetic field (IMF) connection between Sunspot Region 1429 and the Earth, very energetic solar protons have began saturating the Ionosphere. A more delayed effect may result with the CME that was produced with this X flare.  Since the radial propagation speed is expecded to be < 1000km/s with the arrival of the associated CME expected tomorrow March 8, the high solar wind speed accompanying the shock , plus high plasma number densities with a strong southward IMF, we can expect a sudden storm commencement or (SSC).  These geomagnetic storms generally produce large magnetic disturbances due to ring current enhancements.

X5.4 Major Solar Flare from Region 1429 - March 7, 2012


   Updated 03:28 UTC March 7 2012 :

A major X5.4 solar flare has just occured at 00:24 UTC March 7, 2012 followed by a  X1.3 solar flare occurring at 01:14 UTC. 
The X5.4 & X1.3 flares came from sunspot region 1429. This event produced a R3 radio blackout.
Sunspot region 1429 is Earth directed and here was a large dence CME produced with this X class event.
The estimated arrival time of this CME is at between 05:00 and 11:00 UTC March 8th

Update March 9 2012 @ 15:49 UTC:
The CME associated with this event has arrived.

Update on the solar flares:
just issued from NOAA

2012-03-07 01:03   Strong Solar Eruption; Earth-Directed CME Likely
An R3 (Strong) Radio Blackout is now in progress, beginning about 7:00 p.m. EST today. The site of the eruption, previously active Region 1429, is now near center disk, so there's  high-potential of an earth-directed CME. In addition, expect the imminent beginning of a Solar Radiation Storm. Analysis now occurring on both fronts
http://www.swpc.noaa.gov/

the Xray flux was slowly dropping after the X5.4 solar flare, it dropped to around the X1.0 level, and is right now on a slow rise back up

currently at a X1.3
this is seen happening a lot of the time when there is a CME produced with the associated solar flare


Here we see this X flare on sdo EVE

Chances for Strong Flares Increase - March 5, 2012


   Updated 19:31 UTC March 5, 2012 :

Sunspot region 1429 has just has two M flares only minutes apart. A M2.1 flare at 19:16 UTC and a M1.8 flare at 19:30 UTC.

Solar activity has picked up quite a bit since March started.
The X-rays from sunspot region 1429 have been very active today.
Flares produced today, March 5th from region 1429 :
 X1.1 C2.3, C5.8, C1.2, C5.4, C7.8, C9.8, C6.8, M2.1 and a M1.8

The background X-ray flux has not dropping below the C1 range since we had the X1.1 flare today at 04:29 UTC


- Today we have chances for M & X flares from 1429 and chances for M flares from 1428

  NOAA has this to say-
Big sunspot 1429 poses a threat for X-class solar flares
with today:
-a 60% chance for M flares
-a 15% chance for X flares
http://www.swpc.noaa.gov/forecast.html

based on +/- componants within the sunspots
1429 chance for flares right now
-54% chance for M
-50% chance for X
http://spaceweather.inf.brad.ac.uk/monitor.html

We are also seeing a slight rise in Flare chances for southern regions 1428 in the southeastern area, and an unnamed region in the southwestern area

We will be staying on top of today's activity 
Keep checking back for updated information!

From solen:
Minor update added at 17:30 UTC: Region 11429 appears to be preparing for another major flare. The magnetic delta structure shows no signs of weakening, on the contrary, umbrae near the inversion line are bigger and more numerous.
Region 11428 is developing as well and could produce a minor M class flare:
http://www.solen.info/solar/

If regions 1429 and 1428 flare at the same time, this is increase the Xray flare level


A closer look at sunspot region 1429

A solar wind stream flowing from CH505 (minor coronal hole) could reach Earth on March 5-6. A solar wind stream flowing from CH506 (coronal hole) could reach Earth on March 8-9
  SEP flux at energies above 10 MeV started to rise since around 00:00 UT today (probably resulting from the CME associated with yesterday's M2.0 flare). Crossing the threshold of an SEP event is probable in the coming hours. Protons from both CMEs are delayed due to the eastern position of the CME source region. http://www.sidc.oma.be/index.php

Updated CME Information :

STRONG SOLAR ACTIVITY: When the CME from today's X-flare arrives, a geomagnetic storm might already be in progress. An earlier CME is en route and nearing our planet. According to analysts at the Goddard Space Weather Lab, the cloud, which was produced by an M2-class eruption from sunspot AR1429 on March 4th, could deliver a glancing blow to Earth's magnetic field on March 6th at 04:30 UT (+/- 7 hr).

From NOAA:
IA.  Analysis of Solar Active Regions and Activity from  03/2100Z
to 04/2100Z:  Solar activity was moderate.  A long duration M2/1N
flare was observed at 04/1052Z from Region 1429 (N18E55).
Associated with the event was a 750 sfu Tenflare, Type IV Radio
Sweep, and a CME first visible in STEREO B COR 2 Imagery at 04/1210Z
(estimated speed of 840 km/s).  This region is classified as a Dkc
spot group with a Beta-Gamma-Delta magnetic configuration.  Further
analysis of the CME will be necessary as imagery becomes available,
however there appears to be a partial Earth-directed component.  A
glancing blow is possible from this event.

M2.0 LDE Flare from Sunspot 1429


   Updated 07:49 UTC March 5th, 2012 :

Today we had a long duration M2.0 Solar flare that peaked at 10:45 UTC. The source was new large active sunspot region 1429, located at the north east limb. This LDE flare lasted for around 7 hrs. Peaking at 10:45 UTC and finaly dropping to the C1 flare level at around 17:46 UTC.
This event was also associated with a 46min long Radio burst inbounded (Tenflare).

There was a CME produced with this event. Because this CME was ejected on the Eastern limb, it is likely that most of the CME is directed away from earth. However, there was a partial Earth directed portion of this wide CME.
There was also a CME was caused by a filament in the northern region that became unstable on  and was ejected from the solar surface. 

CME Update March 5, 2012:
According to analysts at the Goddard Space Weather Lab, the CME from todays event could deliver a glancing blow to Earth's magnetic field on March 6th at 04:30 UT

More updates to come on todays M2.0 solar flare + CME

Issued from the NOAA Space Weather PRediction Center:
IA.  Analysis of Solar Active Regions and Activity from  03/2100Z
to 04/2100Z:  Solar activity was moderate.  A long duration M2/1N
flare was observed at 04/1052Z from Region 1429 (N18E55).

What is a Tenflare?
 Tenflare: A tenflare is associated with optical and x-ray flares. Solar flares emit radiation over a very wide range of frequencies. One of the more significant frequencies observed is the 10.7 cm wavelength band (2695 MHz). When a solar flare erupts, "noise" from the flare is received over this very wide range of frequencies.
When the noise received on the 10.7 cm wavelength band surpasses 100% of the background noise level during a solar flare, a Tenflare is said to be in progress. The more intense solar flares are associated with tenflares. Almost all major flares are associated with tenflares
http://www.sci.fi/~fmbb/astro/glossar1.htm

From Spaceweather.com
BIG SUNSPOT: A sunspot almost four times as wide as Earth itself is rotating onto the solar disk.
Earth-effects could become stronger as the sunspot turns toward our planet in the days ahead. NOAA forecasters estimate a 55% chance of additional M-class flares and a 5% chance of an X-flare during the next 24 hours
