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.

 

Solar Activity Update - Jan 28, 2012

  
   Update 20:52 UTC Jan 28, 2012 :

We are currently having a S2 Solar radiation Storm that was brought on by yesterdays X1.7 solar flare that peaked at 18:33 UTC Jan 27, 2012.

Solar Storm In Effect - CME Arrived (Updated)

    Update:  Jan 22nd 23:41 UTC
  At this time we are having a G1 Geomagnetic storm.
Geomagnetic conditions are ongoing
So far, conditions peaked between 10:00-12:00 UTC today. Solar winds topped out at speeds over 450km/sec. Density reached  65.6 protons/cm3

Current Solar Conditions:
Wind Speed: 447.9 km/sec
Density: 19.8  protons/cm3
Solar Storm Level - G1 - Minor
Kp Level is now at-  Kp5

High & Mid Latitude Aurora Watch in Effect

CME IMPACT: A coronal mass ejection (CME) hit Earth's magnetic field at 0617 UT on Jan. 22nd. At first the impact did not appear to be a strong one: the solar wind speed barely lifted itself to ~400 km/s when the CME passed by. Now, however, in the wake of the CME, a dense and increasingly geoeffective solar wind stream is blowing around Earth, setting the stage for possible auroras on the night of Jan. 22nd

Solar Activity Update Jan. 16th 2012 - CME With LED Flare

    This is a solar activity update to the LED (long duration event) flare that took place around sunspot region 1402 in the early hours of Jan 16th 2012. This LDE flare lasted about 4 hours, starting at 02:36:00 and ended at 06:46:00 with a peak at around 04:44:00. there was a CME that was produced with this LDE flare as we can see here on STEREO B.

What Happens in a Solar Flare? Sunspot Update - A CME Took Place

    Solar activity increased a bit yesterday. Today its quiet so far but with the active regions on the disc
  we expect more flares during the next days.

    We noticed a CME today on Stereo images. This CME was not earth direced. It will not effect us in any way. Source was a eruption on the farside.

Sunspots Get Numbered

    We talked about yesterday the new numerous Sunpots on the disc get numbered .

Regions 1399 and 1400 emerged onto the solar disc. Regions 1401 and 1402 rotated over the north-east limb. As we all know this are the ones which produced the latest bigger Flares.

Region 1401 yesterday: C4.1 at 12:09, M1.4 at 13:18, C2.8 at 18:40, C2.1 at 21:54, C1.1 at 23:25 UTC. 1401 seems to be the more active one. 1402 above is the bigger one in size. All other groups shows up some changing in size and structure.
Region 1395 decayed slowly and was quiet. Region 1396 became less complex during the day although there is still weak olarity intermixing (flared yesterday morning C 2.1 03:35 UTC). Region 1397 decayed slowly and was quiet. Region 1398 lost penumbral area and gained a few spots. Region 1399 rotated into view at the southeast limb on January 13 and got an SWPC number the next day. This region flared before it rotated on the disc(noticed that on stereo). Region 1400 emerged in the southeast quadrant on January 13 and was assigned an SWPC number the next day.

M1.4 Solar Flare Today From Incoming Region

                                                         

    We have another long duration event. The flare from the active incoming Region on the east limb is still in pogress as you can see and reached now a M flare!

             

We have a M 1.4  today peaking at 13:18 UT from the actice incoming Region on the east limb

   This flare ended up topping out at a M1.4

   

USAF/NOAA Report, New Sunspots numbered

 

   UPDATE-22:35 UT - USAF/NOAA Report of Solar and Geophysical Activity 13 January 2012

Solar activity has been at low levels for the past 24 hours. A filament channel eruption was observed around 12/2130Z in the northern hemisphere around Region 1396 (N26E18). In connection with this event, a CME was observed in LASCO C2 imagery at 12/2136Z.

 

Solar Update Jan. 13th 2012 - New Sunspot + Prominence

 
    The new Sunspot to the east (close to 1395) gets numbered over night as Sunspot Region 1396.

We noticed some changes at Region 1391. There was a quick development in the southern part of the leading spot section. We can also see that the magnetic structure formed as well. Reporting Soleninfo  a chance of  M flare is given from this region.

Region 1395 decayed a bit and produced a C 1.5 at 00:58 UT. Another flare comes from that incoming region which produced the  long duration flare yesterday. A new Region emerged to the southeast.

Prominence Lift Off on the North Limb, CME

UPDATE 23:30 UT

What a day. After this long duration event we notice a pretty new one.

We have a large filament lift off  to the north limb

This produced a CME as we can see on STEREO:

Solar Flare Update - Jan. 12, 2012

   Solar Update 13:50 UTC

We had another climb in the Flux chart. This time it peaks at 13:23UT as a 

C3.3 Flare

   Located at Sunspot Region 1393

LMSAL changed also the Region ( long duration flare )1393 to N30E87 : http://www.lmsal.com/solarsoft/last_events/gev_20120112_0754.html

   We have a Vid of the latest CME and the long duration C Flare. This confirms the possible Location just behind 1395. And the latest Sunspot Update
