Bulletin

Two C-class flare sin past 24h. NOAA AR 1906 produced a C1.4 flare peaking at 00:41 UT, the other one was seen from behind the west limb. More C-class flares can be expected. A partial halo CME was seen by LASCO-C2 at 15:13 UT on November 27, related to a filament eruption in the northern hemisphere. This eruption is mostly directed to the north, but a glancing blow to the Earth is possible. The calculated speed is 540 km/s, giving a probable arrival on November 30 around 17:00 UT. Solar wind speed is very low (260 km/s) with magnetic field around 5nT. Geomagnetic conditions have been quiet and are expected to remain so.

Today's estimated international sunspot number (ISN): 073, based on 07 stations.
