Bulletin

Flaring activity has been very low, no C-class flares in past 24 h. Two simple active regions on the visible disk, Catania 13 (no NOAA number) and Catania 14 (NOAA 2570). No large flares expected (although C-class flares are possible).

Unsettled geomagnetic conditions were registered in the past 24 h, due to the vanishing effect of a high speed solar wind stream. Solar wind speed is now at 480 km/s with interplanetary magnetic field magnitude of 5 nT. Quiet to unsettled conditions are expected for the next 48 h.

Today's estimated international sunspot number (ISN): 019, based on 17 stations.
