Bulletin

Solar activity has been very low over the past 24 hours. Background X-ray flux was around the B2 level, with an occasional B flare (the strongest peaking at B5.9 level at 18:48 UT). Catania sunspot group 20 (NOAA AR 2019) showed no significant growth that would require increasing it's C flaring probability, while the new sunspot group 22 (NOAA unnumbered) does raise the full disc C flare potential. We nevertheless presently maintain the all quiet alert. No significant CME's were observed. Solar wind values became slightly enhanced around UT midnight, fluctuating since then in the 300-360 km/s range. The onset of that period was accompanied by a local maximum of the total magnetic field of over 8 nT, but it has declined continuously since then to around 4 nT presently. Bz was variable within that range. Geomagnetic conditions were quiet with local K Dourbes and NOAA Kp in the 1-2 range. Nominal solar wind conditions and associated quiet geomagnetic conditions are expected over the next days.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 030, gebaseerd op 15 stations.
