Bulletin

During last 24 hours only one C-class flare was reported. The C1.5 flare that peaked at 03:49 UT this morning, originated from the NOAA AR 2770. No obvious on-disc signatures of the possibly associated CME were observed. More will be reported when coronagraph data become available. NOAA AR 2770 has still beta configuration of its photospheric magnetic field, and might be the source of B-class or isolated C-class flares in the coming hours. During last 24 hours there were no Earth directed CMEs and the solar protons remained at the background level.

The solar wind speed is presently about 420 km/s, and the interplanetary magnetic field magnitude is 4 nT. The geomagnetic conditions are quiet, and we expect them to stay so in the coming hours.

Today's estimated international sunspot number (ISN): 011, based on 21 stations.
