Bulletin

Eruptive conditions should persist for the solar activity over the next 48 hours, with C class flares likely from NOAA AR 1817 and 1818, and a slight risk for an isolated M class event from both regions. Active geomagnetic conditions were observed at local levels (Dourbes) during the past 24 hours. Active to minor storm periods were observed at planetary levels. We expect unsettled to active conditions to persist for the next 24 hours and then return to mostly quiet conditions by Aug. 17- Aug. 18. ACE measurements show disturbed Bz and high solar wind speed (around 800 km/s) in relation with the northern coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 067, gebaseerd op 20 stations.
