Bulletin

Flaring activity was yesterday, December 1 and up to this moment today, December 2 limited to the C-level. The probability for C-flares is around 60%, for M-flares around 10% and almost no chance for X-flares. The candidates to populate the flare-club are NOAA AR 1907, 1908 and 1909. Geomagnetic conditions were quiet: K<3. This was due to a positive z-component of the interplanetary magnetic field (IMF). The IMF has although a relatively high value around 10nT. If the z-component turns negative, unsettled conditions are possible. The solar wind speed is decreasing. A coronal hole will approach the central meridian tomorrow.

Today's estimated international sunspot number (ISN): 094, based on 16 stations.
