NOAA AR 2773 has one sunspot and simple alpha magnetic field configuration. This was enough to produce a C1.0 flare, peaking at 00:38 UT. Mostly B-class flares can be expected for the next 24 hours, with C-class flares remaining possible.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay so in the next 24 hours. The greater than 2 MeV electron flux was above the threshold until 21:50 UT on 25 September, when it came back to nominal levels. More enhancements can be expected in the next 48 hours.

Solar wind speed near Earth as registered by DSCOVR ranged between 450 and 560 km/s in the past 24 hours. The Interplanetary Magnetic Field is directed away from the Sun (positive), but it was mostly toward the Sun (negative) during 25 September. It had a magnitude between 3 and 8 nT. Bz reached -5 nT.

Geomagnetic conditions have reached minor storm conditions both locally and at planetary levels (KDourbes = 5 and Kp = 5). The Earth is still inside the fast solar wind from the low latitudinal extension of the northern polar coronal hole. The solar wind speed may still go up in the next 48 hours, causing more storm periods.
