NOAA AR 2773 has lost its sunspot, the Sun is spotless. No flares in the past 24 hours, none expected above the B level.

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 has passed the 10^3 pfu threshold at 03:00 UT, it was also above the threshold five hours starting at 13:30 on 26 September.

Geomagnetic conditions have reached minor storm conditions at planetary levels (Kp = 5) and active conditions locally (KDourbes = 4, but the latest data are missing). The Earth is still inside the fast solar wind from the low latitudinal extension of the northern polar coronal hole. Its influence is fading, mostly unsettled conditions expected for the next 24 hours. In about 48 hours the fast solar wind emanating from a low latitude large area coronal hole (still connected to the northern polar one) will affect the Earth and may cause up to major storm conditions.
