Dear Collaborators,
The target region NOAA 12790 was the source of a C7.4 flare (at 12/07/15:46 UT) and also two ~B6 flares in the past 24 hours. The C7.4 flare was associated with an Earth-directed halo CME. 12790 remains its alpha/H-type configuration and continues to show mixed polarities in its intermediate portion. B-class flares are expected with a chance of an isolated C-class event in the following 24 hours.
The position of NOAA 12790 on December 8 at 04:30 UT is:
S22W18 (280", -365")
