Bulletin

During last 24 hours there were no C-class or larger flares reported. The strongest flare reported was B 1.4 flare (peaked at 09:39 UT this morning). In the coming hours we can expect isolated low B-class flares, originating from the active region presently situated at the East solar limb and rotating to the visible side of the Sun, or occasional fast emerging and decaying active regions. The 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 inside the slow solar wind with the speed of 290 km/s, and the interplanetary magnetic field magnitude is about 4 nT. The geomagnetic conditions are quiet for already more than 5 days and we expect them to remain so in the coming hours.

Today's estimated international sunspot number (ISN): 006, based on 16 stations.
