Long duration C1 flare+Prominence lift off

http://cesar.kso.ac.at/main/last_Ha.php

Still three regions visible.
Largest region so far: 1575 which is a EHO Beta-Gamma type group at 260 millionths in size, which is slightly down from the previous day.
Region 1577 increased from 20 to 100 millionths and is a DAI Beta type group.

 

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.

Large Filament lift off southeast

Update 23:30 UTC:

The filament lift off we see here on the image to the left was maybe a result of a channel eruption

Right after that filament lift off we could see a rly nice explosion (ejecta) also seen on Stereo Ahead EUVI imagery
http://stereo.gsfc.nasa.gov/browse/2012/04/19/behind_20120419_euvi_195_512.mpg

The CME looks really bright. Due to the location of the source (southwest) a direct hit will be probably unlikely. But a portion of it could strife us
 http://stereo.gsfc.nasa.gov/browse/2012/04/19/behind_20120419_cor2_512.mpg

 

Region 1455 says Good bye

We have a new 7.0 C-Class Solar flare as you can see here on the GOES X-ray Flux chart.








We can confirm the location of this event. Its around the old Region 1455 which rotated off the limb yesterday.

We noticed some ejection on SDO AIA 304 Imagery but due to the location it will probably not geo effective




   Region 1463 get official numbered and is now a  DSO type group at 40 millionths in size
All regions increased in size yesterday, region 1459 increased by 110 millions and region 1460 increased by 120 millionths
Most of interest Region 1463. It shows up  several small magnetic delta structures in the central part of the region. So a M Flare from this Region is possible

Near M Flare (C8.9) from an unnumbered region

A near M flare a C 8.9 just took place. Peaking at 12:39 UTC.
http://www.lmsal.com/solarsoft/last_events/gev_20120418_1232.html

We can confirm the location of this event.
It a new region which emerged in the last couple hours. The region is close to the new numbered region 1462

A CME can be possible but we have to check more data

Update 17:50 UTC:
The new spot which is still growing in the southwest quadrant (near Region 1462). Fires up every single hour Mid to High Level C-Class flares
Looks harmonic as we can see on the GOES X-ray Flux Chart




We can see now on Stereo Ahead C2 Imagery
The C 8.9 flare was inbounded with a CME.
It looks not that large but its geo-effective as well

Stay tuned

New CME from northwest filament eruption

We have a new CME as seen on Stereo Images

CME apears to be earth directed

More investigation on this is needed
apears to be earth directed








Latest SDO AIA 304 shows us the source:

Source of this CME is a filament eruption in the northwest

M 1.7 Solar flare and Partial halo CME

UPDATE 04/17/2012 16:00 UTC

A few C-class flares and an M-class flare were observed during the past 24 hours. We expect active conditions with C-class and M-class flares possible. An M1.7 flare was observed by GOES on April 16, peaking at 17:40 UT. The flare originated from an active region (Catania 03; old Sunspot 1442/43) which appeared now on the east limb. The accompanying CME propagated with the speed of about 1300 km/s.

Reporting to Solen.info:

A partial halo CME was observed after the M1 event in region S1592. There's a chance of a flank CME impact on April 19

 http://www.solen.info/solar/

   Region 1459 increased at a more rapid pace to a FHI group at 260 millionths, making it the largest visible sunspot group

New region S1592 [N12E80](associated to the M1 event) rotated into view at the northeast limb and will be soon numbered 1461. nFurther C class and a slight chance of an M class flare are possible over the coming days

Video shows you the increasing Region 1459:

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
 http://www.swpc.noaa.gov/rt_plots/xray_1m.html

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

Region 1402 says "bye" but not without flaring

   We have C5.8 and a C7.9 solar flare from sunspot region 1402, one right after another.

*The first flare was a C5.8 that peaked at 00:36 UTC Jan 26th.

The background Xray level slowly dropped to C1.7, then went on the rise again at 01:40 UTC.

*The second flare was a C7.9 that peaked at 01:49 UTC Jan 26.

   Sunspot regions 1401 and 1402 are now on the Northwest limb and will soon rotate off the western limb out of a Earth facing view. But not without a last "Good bye"! We will have to wait around 20 days for these two very active regions to rotate back in Earths direction

 We also noticed some ejection on SDO

Long Duration (LDE) C Flare, CME , New Sunspot

    Hi Everyone,

In the last hours Solar activity was nearly quiet. However we have a long duration C Flare (Still in pogress).

    LMSAL shows it actually as Region 1393 but watch yourself:

New Site Features!

Hello Everyone :)
A short note here before we get to all the new site features.
We have been wanting to do this blog for you for a long time now. It will be a work in progress, but one that we will enjoy doing. We are super excited to finally have it up and running!
We will be working hard on providing you up to the minute solar news before you can find it anywhere else on the net. Because of this we will not be spending much time in promoting the site,
so any help in sharing the site link would be greatly appreciated :) ,
so here we go...

Region1395 flares, Sunspot Update

    Sunspot Regions 1392 and 1394 decayed and disappeared yesterday. Region 1393 is now on the north-west limb and retained its Beta-Gamma magnetic configuration.Region 1391  lost it and returned to a Beta magnetic configuration.

We notived only 3 solar flares yesterday however this morning we had 3. Two of them took place at Region 1393 and one (we can see that in the image) at Region 1395

Weak effects from CH492 could cause a few unsettled intervals on January 12-13.

Solar Activity Update - Jan 11th 2012 - 00:37 UTC

    We have another Flare again at Sunspot Region 1393. A  C2.2 flare peaks at 00:11 UT

       Latest SDO AIA 304 Helioviewer:

Sunspot Activity Update for Jan. 10th 2012

  
    We noticed some significant Solar change over the last time. Sunspot Region 1391 increased in magnetically complex to a  Beta-Gamma type group. Region 1393 grows again a bit in size, from 250 to 520 millionths but lost a little penumbral area and displayed so far no significant changes otherwise. Region 1389 was quiet and rotates to the southwest limb and will be soon out of view.

    Solar activity was quiet so far. We had a C 1.0 from Region 1393 and a small B 7.1 possible from 1391.  The coronal hole (CH492) in the southern hemisphere is still in Earth facing position. There is a new in the northern hemisphere(CH493). This could rotate into an Earth facing position on January 12. In cause of the Earth facing position from CH492 weak effects from CH492; unsettled intervals on January 12-13 are expected.

Sunspot 1395 Faring , and another farside event

Solar Update   22:30 UT

For now we didnt noticed any CME of this event.

Latest SDO AIA 304 CLOSE UP:

New sunspot says hello with a nice flare

Region 1395 knows how to say "hello"

A  C2.6 peaks at 20:16 UT

It seems to be from Sunspot Region 1395 but as we observed the result was maybe from a Region which is closely behind SunspotRegion 1395.

New Sunspot, Prominence & Flare

   We talked about this yesterday  in the early morning^^

The new Sunspot Region which rotates into view from the east limb gets numbered as 1395 and looks quiet so far

   Sunspot Region 1393 continues to grow and increased in size 100 to 250 millionths, its now a DKI type group

Solar Activity Update for Jan 8th 2012 - 22:38 UT

   Hi,
Solar activity is still quiet. We had some small C Class Flares most of them from Region 1393.

But also 1389 was flaring a bit and will soon rotate from the visible disc.

http://www.lmsal.com/solarsoft/last_events/

Region 1393 grows again a bit and the Region next to it, Region 1392 disappeared
