CME Impact! March 17, 2013

 
   The full halo CME from Friday March 15th has arrived  at Earth early Sunday morning at around 05:30 UTC . The Solar wind and interplanetary magnetic field show a shock signature from this CME now arriving.
At the time the CME came in contact with Earths magnetosphere a geomagnetic disturbance commenced with the Bz fluctuating between minus 20 and plus 15 nanoTeslas.
The Solar wind speed jumped to around 700 km/s and the interplanetary magnetic field Bz component is turbulent around -15 nT.
This brought on a moderate Geomagnetic storm.

   At this time geomagnetic storm level has reached storm levels of G2 (K=6). These conditions are expected to persist well into the early morning hours of tomorrow, Monday March 18.

Aurora may be seen as low as Montana, Michigan, New York, Wisconsin to Washington state, as well as other high latitude regions. To know where Auroras can be seen, look for the Aurora ovation model located in the left hand column of this site.


Any and All updates will be added to the bottom of this report in the spacial 'UPDATE' section. Be sure to check back often through today to find out about any change in conditions.

Long duration C-Class Flare in progress

   We noticed a filament eruption today near Sunspot 1691 - 1690 located in the northern-center area of the solar disk. 

This filament eruption resulted in a 2 hour long LDE C-Class solar flare that occurred starting at 10:17 UTC and ended at 12:25 UTC 
  
We will update this report if we see a Coronal Mass Ejection (CME) associated with this event. 

   UPDATE: There was a  CME (Coronal Mass Ejection) produced in association with todays event as we can see on STEREO B (here to the left). At this time the CME appears to have a mostly northward trajectory. We are still waiting on STEREO A to update so we can better determine if this CME  will be geoeffective. 

 *Continue to check back often for further updates and alerts as today's solar events unfold.

 

Another active Region rotating into view

 

The image to the left from NASA SDO shows regions 1692, 1694 and a new region rotating into view.

New large Region gets numbered as 1692

The animated Image from the SDO shows old sunspot region 1678 as it rotates out of view on the 22rd of February and as it reappears as region 1692 on the 10th of March.

Old Sunspot Region 1678 Returns

   A new active sunspot region is expected to rotate into view during this weekend (March 9-11). This is the well known old sunspot region 1678 making it's return.  In the image to the left we can see also another active region several day's behind it.


   Region 1678 was responsible for the massive CME that occured on the backside of the sun on March 5, 2013 (view that report HERE). Because of the activity sunspot 1678 maintained while on the backside, there has been much anticipation of this sunspot regions return.

Coronal Mass Ejection (CME) Arrives at STEREO

    Maybe you remember the very large solar flare and coronal mass ejection we reported three days ago on March 5. It seems that the Coronal Mass Ejection reached the spacecraft STEREO Behind and the animated image here shows that the Bz component of solar wind remained positive. The time and date can be found in the lower left corner.

That could be one reason why we actually have a time gap on Stereo.

New Sunspot numbered as 1690

  
   We have two sunspot regions which disappeared yesterday while one new region rotated into view over the north-east limb as a single spot HSX Alpha type group at 20 millionths in size and was numbered as region 1690.

 Region 1689 grew from a BXO Beta group at 10 millionths to a DSO Beta type group at 150 millionths in size.

Massive solar flare and CME from old Sunspot 1678

   Old region 1678 which is due to return during this coming weekend produced a MASSIVE solar flare and a spectacular full-halo coronal mass ejection.

   Unfortunately, it is not heading our way because this was a farsided event. But its heading for the STEREO Behind spacecraft.

Minor Geomagnetic Storm

The solar wind continues to increase this morning and is now over 500 km/s. The Bz component of the Interplanetary Magnetic Field (IMF) was tipped sharply south for several hours and a G1 Geomagnetic Storm is currently underway. We expect aurora at very high latitudes!

 Space Weather Alerts and Warnings Timeline

New region 1683 numbered

All three sunspot regions remain visible. The largest region 1682 decreased in size during the last 24 hours. It is now a DAI Beta-gamma type group at 110 millionths in size. New sunspot region 1683 was numbered overnight, it is a HSX Alpha type group at 90 millionths in size. There is now more than one spot visible and a bipolar magnetic configuration.
No C class solar flares took place yesterday, the largest solar flare was a B8 from region 1682. Only C class solar flares are expected today.

Spectacular Prominence Eruption

Early this morning, a prominence located off the southwest limb erupted.

The Sun spewed out a blob of plasma.


Here you get a close up 

As a result of this we notice a outstanding CME on Soho imagery (Soho Lasco C2 here).

Due to the location of this event (southwest limb),
most of the plasma cloud looks to be heading away from Earth.

Full Halo Coronal Mass Ejection (CME)

The STEREO Ahead Spacecraft captured a Full halo Coronal Mass Ejection (CME) this morning. 

The source of this event was a filament eruption inbounded with a solar flare near old region 1678 off the farside of the Sun. 


The Coronal Mass Ejection (CME) will not be geoeffective (farsided event).


Watch the Video down below!

New region rotated into view

Only two small sunspot regions are currently visible. Both are small and quiet so far. However, there is a new region that  rotated into view over the north-east limb. This is a single spot type group and is expected to be quiet. It looks like an 'H' type group with a single (Alpha) magnetic polarity. 'H' type spot groups are usually the last remaining spot of a once multi-spot type group, like the remains of a C or D type group.

Active Sunspot Approaching the North-East Limb

 

  
   There is an active sunspot region approaching the north-east limb that we have been keeping an eye on.

 This  is the return of old Sunspot 1665 that will be rotating into a Earth facing position sometime during this coming weekend.

This sunspot is an active region that has been producing solar flares on the far side of the solar disk over the last couple of days..

We should know by the end of this weekend if this new region will remain active once it rotates into a Earth facing Position or fizzle out.

 

Bright Coronal Mass Ejection (CME) observed

 

A bright coronal mass ejection took place from the north-west limb yesterday.

The majority of the cloud is heading north as we will see on the CME prediction model.

However a glancing blow will be possible on February 22nd.

Finally some solar activity! M 1.9 Solar flare around Region 1675

                                                                                                                                            

  After a long while a M 1.9 solar flare took place. Maxed out at 15:50 UTC.

                                                          

Two new regions numbered and filament lift off

We have two new regions. The first is region 1675, which is a BXO Beta type group at 10 millionths in size. On my thoughts, this region is a larger type group and also in size larger than reported. There may even be a Beta-Gamma developing in the central portion of the group. This region emerged onto the solar disc. The second is region 1676, which is a single spot HAX Alpha type group at 30 millionths in size. This region rotated over the south-east limb. We also have  a couple of other sunspot region which are visible but are not numbered yet.

Meteor hits central russia it wasnt 2012 DA14! It's still up there

Apparently, at about 09:30 local time, a very big meteor burned up over Chelyabinsk, a city in Russia just east of the Ural mountains, and about 1500 kilometers east of Moscow. A pretty big sonic boom from the fireball, which set off car alarms and shattered windows. There are reports of many people injured (by shattered glass blown out by the shock wave).






Here's a video collection of the Ural Meteorit:

A vast collection of internet videos showing "Tuguska Light" (is there an 'official' term by now?) and its aftermath (Photo of the meteorite from the space and the 6-meter wide crater at Lake Chebarkul included) :

CME arrival soon and sunspot update

   One new region was numbered overnight; this was region 1464 which is located just to the north of region 1460, and is a BXO type group at 10 millionths in size.

    Region 1459 decayed in size from a EKC group at 250 millionths, to a DSI at 180 millionths.

Most other groups increased slightly in size.

Numerous C class solar flares took place yesterday, the largest was a C7 peaking at 1126z from region 1455 that rotated out of view 2 days ago.

This region produced a large coronal mass ejection that is not Earth directed.

A C1 solar flare from region 1462 also produced a coronal mass ejection that may have an Earthward component. The geomagnetic field is expected to be quiet to active on April 20.

The CME observed on April 18 could reach Earth on April 21, and cause  active conditions through April 22.

 An Aurora watch will be in effect for the next 72 hours.
