Bulletin

The background X-ray radiation is situated in the top B-level (B7). The strongest solar flare was a C3.6 flare originating from Catania sunspot region 80 (NOAA AR 1917). The probability for C-flares is around 70%, M-flares around 20%, the chances for an X-flare are low. The >10MeV proton flux measured by GOES had a small bump, but remained below the event threshold (10 pfu) and is now back at background level. The origin of this enhancement currently is unclear. No Earth directed CMEs were observed in coronagraphic data. We are currently inside a slow solar wind stream with a solar wind speed of 400 km/s, as observed by ACE. The interplanetary magnetic field currently is weak with a magnitude of about 5 nT. Geomagnetic conditions are quiet (K<3) to unsettled (K=3) and are expected to remain so.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 080, gebaseerd op 11 stations.
