Bulletin

The risk for an isolated M class flare still exists from NOAA ARs 1893 and 1897, but C flares are more likely to occur in the coming 48 hours, from these regions and ARs 1899 and 1900. The past 24 hours were rather low in terms of flaring activity, with only moderate C class flares. We expect quiet geomagnetic conditions to prevail for the next 48 hours. Current interplanetary conditions are quiet.

Today's estimated international sunspot number (ISN): 112, based on 03 stations.
