Bulletin

Five sunspot groups were reported by NOAA today. The strongest flare of the past 24 hours was the C1.3 flare peaking in the NOAA AR 2497 at 15:22 UT yesterday. This group maintains beta-gamma configuration of its photospheric magnetic field. We expect flaring activity on the C-level. The Earth is currently inside a slow (around 330 km/s) solar wind flow. The interplanetary magnetic field (IMF) magnitude is slightly elevated (around 6 nT). The IMF north-south component Bz is consistently southward since yesterday afternoon, but due to low solar wind speed the geomagnetic conditions are on the quiet to unsettled level. We do not expect the geomagnetic conditions to vary much, except if the solar wind speed will increase, in which case active geomagnetic conditions may be possible.

Today's estimated international sunspot number (ISN): 088, based on 14 stations.
