Dear Colleagues,
Solar activity has increased to a medium level since the last message. The largest event was an M4.9 event at 2:00 UT today(2/23) from NOAA 14001 approaching the West limb. This region produced 2 C8 class flares yesterday and another M class flare today (M1.6 at 11:47 UT) but will complete the limb passage today.
The target region, NOAA 14000 developed mix polarity in the following sunspots and now classified as a beta-gamma-delta type. However, it is kind of dormant with respect to flare activity with no flare record in the past 24 hours. On the other hand, NOAA 13998 underwent significant flux emergence with its size increased from 220 to 280 millionths during the past 24 hours. This region is producing more than 10 C class flares and an M1.0 at 09:54 UT today, showing rapid sunspot movements. Today we will observe NOAA 13998 at the region of new sunspots for the next 24 hours.
The position of the target in NOAA 13998 on 23-February-2025 at 16:30 UT is:
S12W23 , ( 371", -102" ).
