Dear Collaborators,
Solar activity on the visible side of the disk has been very low since the last message. However, an M4.5 flare was observed from behind the Southeast limb (at the latitude ~26 deg.) at 23:08 UT yesterday(4/18) associated with a significant CME. The source region of this flare is not visible from us yet.
The largest event on the disk in the past 24 hours was a C2.7 flare at 21:48 UT yesterday from NOAA 14064. This region grew significantly in size to 350 millionths and shows sunspot motion in the area of trailing (negative) sunspots. While on the contrary, the target region, NOAA 14062, did not show flare activity during the past 24 hours.
Today, we will switch the default target to NOAA 14064, on the trailing sunspot area mentioned in the above. Additional C class events are expected.
The position of the target in NOAA 14064 on 19-April-2025 at 15:00 UT is: N09E40 (-608", 226").
