Dear Collaborators,
Solar activity has declined to a low level after the X1.9 event
yesterday(12/1). The source region of the X class flare, which is the
target of the current Major Flare Watch campaign, was numbered NOAA
14299, classified as a beta-gamma/D-type, but has been in a dormant
state after the X class event.
The largest event in the past 24 hours was a C4.8 flare at 21:06 UT
yesterday from the middle portion of NOAA 14294. This region maintains
the size over 1400 millionths and a beta-gamma-delta magnetic
configuration, even after the westernmost area of this region was
re-classified as an alpha-type sunspot with a new number, NOAA 14298.
NOAA 14298, 14294 and their eastern adjacent region NOAA 14296 forms
a huge active region group with a total size over 2000 millionths.
More than 10 low-to-mid C class flares were reported from this active region
group, however none of them has not exceeded a high-C level.
Today, we will continue the Major Flare Watch campaign for another 24
hours on NOAA 14299, expecting additional activities including an event
larger than M5.
