Dear Collaborators,

Solar activity has been at high levels for the past 24 hours. The largest event since the last message was an X1.0 flare at 01/10/22:39 UT produced by the northeast limb region mentioned in the last message, now numbered as NOAA 13186. 13186 also produced three low M-class flares (M1.4, M2.4, and M3.1) and six C-class flares. Today the Major Flare Watch region will switch to NOAA 13186 that has been classified as a beta-delta/D-type configuration. Yesterday's target NOAA 13184 (S13E48) produced an M5.6 flare at 01/11/01:49 UT and also an M1.2 plus two C-class flares. This region has been designated as a beta-delta/ E-type region. In addition, NOAA 13181 produced an M1.3 flare and was designated as a beta-gamma/E-type region. Further M-class (including above M5) flares are expected from various regions in the next 24-48 hours.

The position of NOAA 13186 on January 11 at 08:30 UT

N25E60 (-766", 443")
