Dear Collaborators,
Solar activity has been at a very low level since the last message. The largest event during the period was a C2.3 flare at 12:23 UT yesterday produced by the target region NOAA 13553. 13553 also produced another two flares (C2.2 and C1.3). It retains a beta/C-type configuration. Today we will continue to watch this region for a further 24 hours. Please note that a newly numbered region NOAA 13559 was designated as a beta/D-type configuration and is showing magnetic flux emergence, which has a potential to produce high C-class flares in the next few days. Further C-class activities are expected from the target region and also from 13559.
The position of NOAA 13553 on January 19 at 08:30 UT is:
N05W02 (34", 168")
