Bulletin

Two C-class flares occurred this morning. A C6.8 flare was observed at 00:56 UT on the east limb near the location where AR 1895 and 1897 are expected to return. AR 1897 produced M-class flares during its previous rotation. A C4.7 flare occurred in AR 1907 on the west limb, peaking at 04:58 UT. This flare was associated with a CME observed in SOHO/LASCO and STEREO-A/COR2 around 06:00 UT after a data gap. This CME is not earth-directed. Geomagnetic conditions are currently at quiet levels (KDourbes = 2). We expect possible unsettled conditions on December 7 due to the arrival of a fast wind stream originating from a coronal hole that passed the central meridian today.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 086, gebaseerd op 08 stations.
