Dear Collaborators,
The largest X-ray event was a B8.3 flare (at 23:32 UT on December 6) since the last message, which was produced by the target region NOAA 12790. NOAA 12791 (beta/B-type) also produced two B-class flares (a B3.5 and a B3.6 on December 7). 12790 has been designated as an alpha/H-type region and in its decay phase. We will watch this region for a further 24 hours. B-class flares are expected in the next 24 hours.
The position of NOAA 12790 on December 7 at 04:30 UT is:
S23W05 (78", -383")
