Bulletin

Catania sunspot group 45 (NOAA AR region 2776) that just rotated over the East solar limb to the visible side of the Sun, was the source of several low B-class flares, the only reported flaring activity during last 24 hours. Occasional B-class flares can be expected in the coming hours while C-class flares are possible but not very probable. The available coronagraph data do not show any possibly Earth directed CMEs. The proton flux levels remain at the background values.

Earth is still inside the slow solar wind with the speed of 260 km/s, while the interplanetary magnetic field magnitude is about 3 nT. The geomagnetic conditions are quiet, and we expect them to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 013, based on 14 stations.
