Bulletin

The solar activity was quiet over the past 24 hours. The X-ray flux remained below B-class level. The two sunspots (NOAA-AR 2770 and NOAA- AR 2771) have now decayed into pages. The solar activity is expected to remain at low levels.

No Earth directed Coronal Mass Ejections (CMEs) were observed in the available coronagraphic imagery in the last 24 hours.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels for the next 24 hours. The greater than 2 MeV electron flux reached moderate levels over the past 24 hours and is expected to reach up to moderate levels over the next 24 hours.

The Earth continued to be under the influence of the slow solar wind streams with the solar wind speed around 275-320 km/s, the total interplanetary magnetic field below 5 nT, and the Bz magnetic field components fluctuating between -4 nT and +4 nT. The solar wind conditions are expected to remain mostly nominal for the next days.

Geomagnetic conditions were quiet, and quiet conditions are expected for the next following days.

Today's estimated international sunspot number (ISN): 006, based on 17 stations.
