Bulletin

Solar activity is very low with only one B-class flare reported during last 24 hours. Catania sunspot group 73 (NOAA AR 2007) has rotated behind the west solar limb and there are presently no numbered active regions on the visible side of the solar disc. We expect low solar activity to continue in the coming hours with very low probability of flaring, even on the B-class level. Coronagraph images do not show signatures of the Earth directed CMEs, and the solar protons remained at the background level.

The solar wind speed is presently about 370 km/s and the interplanetary magnetic field magnitude is 3 nT. The increase of the solar wind speed (up to 460 km/s), interplanetary magnetic field (up to 10 nT) and temperature, simultaneously with decrease of density observed during last 24 hours are probably associated with the equatorial coronal hole, which reached central meridian in the morning of February 26. 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 24 stations.
