Bulletin

Six sunspot groups were reported by Catania today, and non of them was particularly active. Strongest flare among five C-class flares reported during last 24 hours flare was C3.6 flare, peaking at 10:55 UT on July 15. The flare originated from the Catania sunspot group 30 (NOAA AR 1791). We expect C-class flares and possibly, but not probably, also M-class flares. The interplanetary magnetic field magnitude is about 6 nT, and the solar wind speed is 400 km/s. The extended low-latitude coronal hole in the northern hemisphere is passing the central meridian. The arrival of the fast solar wind at the Earth is expected on July 18. The arrival of the CME from July 13, although not probable, is expected early on July 18. We expect quiet to unsettled geomagnetic conditions during following 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 050, gebaseerd op 20 stations.
