Bulletin

The solar flaring activity is very low with only B-class flares reported in the last 48 hours. As there are no complex active regions observed on the visible side of the solar disc, we expect such a low level of flaring activity to continue in the coming hours. During last 24 hours there were no potentially Earth-directed CMEs detected in the available coronagraph observations.

The greater than 10 MeV proton flux remained at the background levels, and the greater than 2 MeV electron flux was under the 1000 pfu threshold during last several days. The 24h electron fluence is at moderate to normal level, and we expect it will remain so in the coming hours.

The solar wind speed has decreased and it is presently about the 415 km/s. The interplanetary magnetic field magnitude is about 7 nT. During last 24 hours the geomagnetic conditions were mostly unsettled. We can expect unsettled to quiet geomagnetic conditions to persist in the coming hours.

Today's estimated international sunspot number (ISN): 067, based on 10 stations.
