Bulletin

Solar activity was moderate during the last 24 hours, with several C-class flares occurring in NOAA ARs 1731, 1733 and a yet unnumbered AR at S19E79 (Catania 59). These 3 regions are the main candidates for further C class flares in the next 48 hours, with even a risk for an isolated M flare from NOAA ARs 1731 and 1733. Several CMEs occurred in the last 24 hours, one at 1325 UT on April 28, in the vicinity of Cat. AR 59, behind the limb, one at 2112 UT on the same day, related to a C4.4 flare in NOAA AR 1733, and one on April 29 around 0324 UT, linked to a filament eruption in the vicinity of AR 1732. None of these events appear to be geoeffective. We expect geomagnetic activity to remain at quiet levels for the next 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 094, gebaseerd op 14 stations.
