Bulletin

Solar activity was eruptive with 7 C flares mostly originating from NOAA 1750 (Catania 78) and 1 M1.7 flare from an active region just behind the east limb peaking on May 20th 05:25 UT. There is insufficient data available to determine an associated CME, but chances for arrival on Earth are very low due to its location. Because the active region 1750 on the West limb can still produce M flares, there is a possibility for a proton event. A shock corresponding to the CME of May 17th arrived to the Earth at 22:23 UT on May 19 causing active geomagnetic conditions (K Dourbes = 4). Geomagnetic conditions are currently quiet again and are expected to remain so for the next 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 077, gebaseerd op 08 stations.
