Bulletin

Solar flaring activity remains very low without any B-class or C-class flares reported. Since presently there are no active regions observed on the visible side of the Sun, we expect such a low activity to persist in the coming days. There were no Earth directed CMEs reported during last 24 hours and the solar protons remained at the background level.

The solar wind speed is presently about 400 km/s and the interplanetary magnetic field magnitude is about 3 nT. The geomagnetic conditions are presently quiet, and we can expect quiet to unsettled geomagnetic conditions in the coming hours. The geomagnetic conditions could turn to unsettled to active, late on November 30 and December 1 due to expected arrival of the fast solar wind associated with extended equatorial coronal hole.

Today's estimated international sunspot number (ISN): 000, based on 12 stations.
