Bulletin

Solar activity decreased even more, there was not C-class flares reported during last 24 hours. For out of nine numbered sunspot groups on the solar disc have beta configuration of its photospehric magnetic field, therefore the C-class flares are still possible. The solar wind speed is about 420 km/s, and the interplanetary magnetic field magnitude is about 3 nT. The geomagnetic conditions are at the moment quiet. We expect quiet to possibly active geomagnetic conditions in the following 48 hours due to the arrival of a fast flow (associated with the low-latitude coronal hole in the northern hemisphere) and the CME associated with the prominence eruption from September 19.

Today's estimated international sunspot number (ISN): 050, based on 05 stations.
