Dear Collaborators,

The target region NOAA 12871 was the source of about ten B-class flares as well as two C-class flares (C1.0 and C1.7, with the latter one at 09/25/19:11 UT) in the past 24 hours. 12871 retains its beta/D-type configuration. It shows flux cancellation and also flux emergence in its northern part. Further B- and also C-class activities are expected with a light chance of an isolated low M-class flare in the next 24 hours.

The position of NOAA 12871 on September 26 at 03:30 UT is:

S28W15 (219", -546")
