Dear Collaborators,
Solar activity continues at a very low level. The largest event in the past 24 hours was a C4.1 flare at 09/18/03:33 UT produced by NOAA 13828 (S13E57, alpha/H-type). 13828 also produced another two low C-class flares. The target region NOAA 13825 was the source of two low C-class flares (C2.4 and C1.6) in the period, which retains a beta-gamma/E-type configuration. At this time, we are ending the Major Flare Watch campaign. Further C-class activities are expected with a small chance of an M-class flare in the next 24 hours.
The position of NOAA 13825 on September 18 at 07:30 UT is:
S15E02 (-32", -361")
