Bulletin

NOAA 2487 produced the only C-class flare of the period, a C1.4 peaking at 13:51UT. The event lasted for 57 minutes (x-ray) and was associated with a relatively narrow coronal mass ejection (CME) that was not directed to Earth. The nearby 20 degrees long north-south oriented filament remained stable. NOAA 2486 was decaying. No earth-directed CMEs were observed.

There remains a chance on an isolated C-class flare. . The earth environment remained under the influence of the high speed stream of the southern polar coronal hole (CH). Solar wind started and ended the period with a speed of around 500 km/s, meanwhile reaching a maximum speed of about 550 km/s early on 22 January (02UT-05UT). Bz undulated between -7 nT and + 6 nT, while the interplanetary magnetic field was directed towards the Sun. Mostly active geomagnetic conditions were recorded, with locally (Dourbes) minor storming during the 22-23UT interval. The extension of a northern polar CH around +25 degrees latitude is transiting the central meridian.

Mostly quiet to unsettled geomagnetic conditions are expected, with a chance on an active episode.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 060, gebaseerd op 11 stations.
