Bulletin

NOAA AR 1907 and 1908 were responsible for the C-flaring activity today November 29 and yesterday, November 28. We expect more C-flares. NOAA AR 1909 is also in the running for C-flaring activity. Solar wind speed is below 300 km/s. The slow wind carries an average total interplanetary magnetic field (IMF) below 10nT. The earth entered another sector causing unsettled geomagnetic conditions on the planetary level (Kp=3). Further we expect quiet geomagnetic conditions for the rest of the UT day. Tomorrow, November 30, a glancing blow of the filament eruption of November 27 is possible.

Today's estimated international sunspot number (ISN): 074, based on 05 stations.
