Solar activity is low. The strongest flare, among three C-class flares reported during last 24 hours was a C3.3 flare (peak time at 18:32 UT) on September 19. The flare originated from the NOAA AR 2171 currently situated at the east solar limb. Solar activity is expected to remain low with occasional C-class flares. The solar wind speed is about 500 km/s. In the wake of the passage of the interaction region between the fast and slow solar wind flow the interplanetary magnetic field magnitude has decreased to low values and it currently amounts about 5nT. The geomagnetic conditions are quiet and expected to remain so in the following 48 hours.
Today's estimated international sunspot number (ISN): 045, based on 11 stations.
