Dear Collaborators,
Solar activity has grown to a high level. The largest event since the last message was a partially occulted M5.5 flare at 16:52 UT on 11-Apr-2024 from two unnumbered regions behind the east limb. This event was very eruptive and the two limb regions are connected by large trans-equatorial loops. At this point, we are implementing a Major Flare Watch on the limb region in the northeast quadrant. Please also include the southeast one (S18E88) if possible. Further C-class activities are expected with a good chance of another >M5 flare in the next 24 hours.
The approximate position of the target on 12-Apr-2024 at 11:30 UT is:
N17E87 (-950", 300")
