Bulletin

Solar activity is low, and there were no C-class flares reported today. The only sunspot group observed on the visible side of the solar disc during last several days, NOAA AR 2728 (not numbered by Catania) has almost completely decayed. We do not expect C-class flares or larger in the following days. No Earth directed CMEs were observed during last 24 hours, and the solar protons remained at the background level.

The solar wind speed increased somewhat today and it presently amounts about 370 km/s. The interplanetary magnetic field magnitude is about 6 nT. Large equatorial coronal hole has reached central meridian this morning, and the associated fast solar wind is expected to arrive to the Earth on November 30 or early on December 01. The geomagnetic conditions are presently quiet, and we can expect quiet to unsettled geomagnetic conditions in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 14 stations.
