It has been designated as a beta-gamma-delta/D-type configuration with increasing the number of spots significantly. Today the Major Flare Watch campaign continues on this region. Low M-class activities are expected with a chance of a major flare in the next few days.

The position of NOAA 13825 on September 15 at 15:30 UT is:

S18E39 (-572", -381")
