Bulletin

Catania sunspot groups 70 and 72 (NOAA ARs 1660 and 1661 respectively), as well as yet unnumbered sunspot group that emerged close to the east limb yesterday evening, have a potential to produce a C-class flare. Three flares stronger than B5 were produced in Catania sunspot groups 70 and 72 during the last 24 hours. A C-class flare is therefore possible. The Earth is currently inside a fast (around 500 km/s) solar wind flow with elevated (around 10 nT) interplanetary magnetic field magnitude. Active geomagnetic conditions (K = 4) were reported by NOAA and IZMIRAN, and unsettled conditions (K = 3) were reported by Dourbes. More intervals of active geomagnetic conditions are possible, especially after the arrival of the ICME-driven shock that is expected late today - early tomorrow.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 042, gebaseerd op 07 stations.
