Bulletin

There are currently ten numbered sunspot groups visible on the solar disc, majority of them having beta configuration of their photospheric magnetic field. The solar activity remains low with no C-class flares reported during the last 24 hours. The strongest reported flare was B4.7 flare which peaked at 10:56 UT on March 5. The flare originated from the Catania sunspot group 27 (NOAA 2506) currently situated at the West solar limb. We might expect isolated C-class flares (probability is about 35 %) in the coming hours. No Earth directed CMEs were observed in the last 24 hours.

The solar wind speed and the interplanetary magnetic field magnitude did not show significant change in last 24 hours, and their average values are still about 380 km/s and 5 nT, respectively. The arrival of the fast solar wind associated with the small equatorial coronal hole which reached the central meridian in the morning of March 2, might be expected at the Earth today. The geomagnetic conditions are currently quiet, we expect quiet to unsettled geomagnetic conditions in the coming hours.

Today's estimated international sunspot number (ISN): 075, based on 06 stations.
