Dear Collaborators,
Solar activity has increased since the last message. The target
region NOAA 12907 was the source of more than ten C-class
flares (the largest one being a C6.0 flare at 12/14/23:44 UT).
12907 has been classified as a Beta-Gamma/D-type region.
NOAA 12906 (S29E21, beta/C-type) also produced a C1.6 flare
as well as a few B-class events. Note that there emerged a new
region with sunspots (around S20E70) near the target region.
If possible, please also include this new region in your field of view,
which shows a rapidly increased current helicity. More C-class
activities are expected with a chance of an M-class flare in the
next 24 hours.
The position of NOAA 12907 on December 15 at 04:30 UT is:
S21E46 (-656", -339")
