The SIDC is part of the Royal Observatory of Belgium and a partner in the Solar Terrestrial Center of Excellence (STCE).

INFO FROM SIDC - RWC BELGIUM 2020 Sep 25 12:30UTC

The x-ray flux has remained at the A level in the past 24 hours, no flares
observed, the situation is not expected to change for the next 24 hours. 

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 at nominal levels in the next 24 hours. The
greater than 2 MeV electron flux passed slightly the 10^3 pfu threshold at
15:30 UT on 24 September, at 21:35 UT it came back to nominal levels but
stayed very close to the limit. At 10:30 UT today it went above the
threshold again, these flux enhancements are expected to remain present for
the next 48 hours.

Solar wind speed near Earth as registered by DSCOVR ranged between 450 and
530 km/s in the past 24 hours. The Interplanetary Magnetic Field is
directed away from the Sun (positive). It had a magnitude between 3 and 6
nT. Bz reached -6 nT.
 
Geomagnetic conditions have ranged from 0 to 4 both locally and at
planetary levels. The Earth is still inside the relatively fast solar wind
from a coronal hole. The solar wind speed may still go up in the next 48
hours, since the shape of the coronal hole is irregular. Mostly unsettled
to active conditions expected (with possible isolated minor storm
periods).
