Bulletin

Very quiet solar conditions are expected for the next 48 hours. Geomagnetic activity is expected to be unsettled for the next 24 hours, with possibly isolated periods of active conditions. We had, in the past 24 hours, active conditions at planetary levels, due to the effect of a coronal hole. Current conditions are quiet.

Today's estimated international sunspot number (ISN): 029, based on 12 stations.
