During last 24 hours solar flaring activity was at the B-class level, with the source regions of the flares in the Catania sunspot groups 2 and 3 (NOAA ARs 2829 and 2830, respectively). We expect such a low level of flaring activity to continue in the coming hours. There were no Earth directed CMEs observed during last 24 hours and the proton flux levels remained at background values.
The greater than 2MeV electron flux was bellow the 1000 pfu threshold in the past 24 hours and is expected to remain so during the next 24 hours. The 24h electron fluence was at normal levels and it is expected to stay so in the coming 24 hours.
The solar wind speed is presently 370 km/s and the interplanetary magnetic field magnitude is about 8 nT. The in situ observations indicate possible arrival of the solar wind originating from the negative polarity coronal hole, seemingly the extension of the southern polar coronal hole. It will be more clear when longer interval of the in situ data becomes available. The geomagnetic conditions are presently quiet to unsettled and we expect them to stay so in the coming hours.
Today's estimated international sunspot number (ISN): 051, based on 24 stations.
