Bulletin

Solar activity has been very low, no C-class flares in past 24 h. All the active regions on the visible solar disk have simple configuration, only C-class flares can be expected. Geomagnetic conditions are quiet and expected to remain so until the arrival of the fast speed stream from a small equatorial coronal hole within 24 h. The solar wind speed is currently at 375 km/s with interplanetary magnetic field intensity of 5 nT.

Today's estimated international sunspot number (ISN): 038, based on 15 stations.
