Bulletin

NOAA ARs 2087 and 2089 have beta-gamma configuration of their photospheric magnetic field. The strongest flare of the past 24 hours was the C4.0 flare peaking at 03:31 UT today in the NOAA AR 2087. The flare was associated with coronal dimmings and a post-eruptive arcade observed by SDO/AIA, and also probably with a narrow CME first seen in the SOHO/LASCO C2 field of view at 07:48 UT. The CME is not expected to arrive at the Earth. We expect further flaring activity on the C-level, in particular from NOAA ARs 2087 and 2093, with an M-class flare being possible but not very likely. An interplanetary sector boundary was crossed around 17:00 UT yesterday. The interplanetary magnetic field (IMF) magnitude increased up to 10 nT, but it did not exhibit prolonged intervals of strongly negative north-south component Bz. The geomagnetic conditions were quiet to unsettled. The Earth is currently inside a slow (around 400 km/s) solar wind flow with slightly elevated (around 6 nT) IMF magnitude. The geomagnetic conditions are quiet and are expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 085, gebaseerd op 14 stations.
