Bulletin

There are presently no numbered active regions observed on the visible side of the Sun (NOAA AR 2750 just rotated behind the west solar limb). The solar flaring activity is accordingly very low, with no reported flares during last 24 hours. We expect such a low level of the solar flaring activity to continue in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.

The solar wind speed is presently 310 km/s and the interplanetary magnetic field magnitude is about 4 nT. The arrival of the fast solar wind associated with the patchy equatorial, negative polarity coronal hole is still expected later today. The geomagnetic conditions are presently quiet and we expect quiet to unsettled geomagnetic conditions in the coming hours.

Today's estimated international sunspot number (ISN): 000, based on 22 stations.
