Dear Collaborators,
Solar activity has been at a low level since the last message. The largest event of the period was a C3.2 flare at 19:58 UT yesterday, produced by NOAA 14317 which just rotated onto the visible disk. 14317 also produced five C1-C2 flares. It was designated as a beta/D-type configuration and has the largest sunspot area. Today the target will switch to this region. Yesterday's target NOAA 14312 only produced a C2.7 flare and retains an alpha/H-type configuration. Further C-class activities are expected in the next 24 hours.
The approximate position of NOAA 14317 on December 21 at 08:00 UT is: N13E69 (-930", 200")
