LDE M Flare in Progress - CME Watch In Effect!

   Out of nowhere! At this time there is a LDE (long duration event) M flare in progress . This M class solar flare event began today, March 15th just before 06:00 UTC and is currently at a M1.2 reading. The source of this LDE M flare is sunspot 1692 that is located in the very northern center of the solar disk..  Long duration events such as we are seeing right now are commonly associated with CME's. Because of this, we will be watching close for any signs of a CME that may be ejected toward Earth as well as what sunspot this event took place around.

Today's M flare event started taking place at the same time SWPC issued an alert that there is a Geomagnetic Sudden Impulse. This indicated that the CME we were expecting for March 15th has now arrived

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.

C Class LDE, CME & Proton Event (NOAA Scale S1)

    On May 26, 2012 at approximately 20:47 UTC, a large backside solar eruption occured off of the far west limb of the solar disk producing a backside asymetrical halo CME observed by SOHO LASCO C/2 and C/3.This CME is not expected to be geoeffective. Along with this eruption, Type II, and Type IV radio emmissions were observed. This event began a 10 MeV proton event (NOAA Scale S1), Solar Radiation Storm, that onset May 27 05:05 UTC, with potential impacts being "Minor impacts on polar HF (high frequency) radio propagation resulting in fades at lower frequencies".

   This Event was followed by a LDE (Long Duration Event), C 3.1 flare from Region 1492, lasting from 04:35 untill 07:00 UTC May 27, 2012. This LDE further elevated the proton count ending with a 10 MeV proton event that peaked at 2012 May 27 10:45 UTC, End Time: 2012 May 27 1235 UTC, Maximum 10MeV Flux: 14 pfu. Along with this LDE C class flare there was a CME eruption observed from SOHO Lasco C/2 and C/3. Although not highly Earth directed, CMEs produced from this region of the solar surface generally provide Earth with a "glancing blow", so we expect to see an uptic in geomanetic activity with its arrival May 29th - 30th.

Sunspot Region 1410 LDE Flare In Progress

   There has been a slow steady rise in the Xray flux over the last few hours starting around 20:30 UTC. This is due to an ongoing flare around sunspot region 1410 located on the far western limb of the solar disk.

Update 00:09 UTC Feb 8, 2012 :
This LDE peaked at C7.3 and  is now on a slow drop, currently at C2.3

We will update on the flare situation as conditions change.
Keep checking back

LDE Flare In Progress

  
   Latest Update - 08:17 UTC
   Jan 26, 2012 :

We have yet another LDE (long duration event) Flare in progress. This flare began around 04:09 UTC and reached a max of C6.4 at 05:49 UTC. This is the third LDE of 2012.

Keep checking back for current updates!

   There was a CME associated with

this LDE flare. Due to the location of 1402 on the far Northwest area of the solar disk, this CME is most likley not Earth directed

 

 

Another LDE M Flare and 2 CME's - Jan 23 2012

Update @ 22:18 UTC Jan 23, 2012:

 

Event Summery:

-The CME's are Earth directed.

-CME speed is 2200 km/s

-Will arrive on Jan 24, 2012 - 1 day after ejection 

-There was a R2 radio Blackout with this M flare

-There was Proton event associated this this event
-Strongest Proton event since 2003
-S3 Solar Radiation Storm is now in progress

Read full report for all details!

*A strong S3 Level radiation storm is still in progress.

This is the strongest proton event since 2003!

 NOAA Correction and New Data Update:
Issued 16:30 UTC Jan 24, 2012
Here we see a plot of the Protons and it shows the secondary increase of 10 MeV protons as the CME arrived.

Earlier, it was stated that the current Solar Radiation Storm was the largest since May 2005, when the 10 MeV protons exceeded over 3000 PFU. This was not correct.
At the time of the earlier post, this current Storm was the biggest since January 2005, when the 10 MeV flux was 5040 pfu. After the arrival of the CME earlier today, the 10 MeV flux again increased and we were at around 6300 pfu. This is now the largest Solar Radiation Storm since October 2003. (The Halloween Storms)

CME arrives as expected.

 
    At approximately 04:01 UTC the CME that accompanied the January 16th LDE C 6.5 flare from Sunspot Region 1402 arrived.  At 04:01 ACE data showed an increase in proton density from 1.6 P/cc to 8.3P/cc and an uptick in the solar wind from 301.1 K/ps to 343.5 K/ps. This is just the first in a wave of CMEs expected over the next couple of days. This CME is only expected to give a glancing blow, as the majority of it will sweep past Earth in a northward direction. We will be anxiously awaiting the arrival of a larger double CME wave that was associated with the M3.2 LDE on thursday the 19th.  The Next CME is expected to arrive Sunday into Monday UTC. Be sure to check back for updates on these developing events.

    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.

Long Duration Flare and CME

At the time of this post we are currently seeing a LDE (long duration event) flare from a new sunspot region located off of the NE limb. New Region 1402 is a large DHO class Sunspot Region with a spot count of 7. This ongoing flare is currently at C 6.4, and the latest Stereo images are showing that a CME is accompanying this event. Pictured below are images from SDO EVE, SOHO, SDO AIA 171 telescope, and Stereo Behind, of this ongoing flare and CME. Images Courtesy of NASA SDO, Stereo, SOHO, and GOES.

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:
