Bulletin

Over the last 24 hours, only one C-class flare was observed. This C1-flare peaked on 31 May at 07:05UT, and originated from the active region that is about to round the east-northeast limb. There are currently 5 sunspot groups visible. They are all small and magnetically simple. There's a small chance on a C-class flare, in particular from the region near the east-northeast limb. Solar wind speed varied mostly between 320 and 360 km/s. Bz was initially negative with excursions up to -11nT. Around 19:00UT on 30 May, Bz turned positive reaching +10nT, and stayed mostly positive for the remainder of the period. The geomagnetic field was quiet with locally an active episode. A small coronal hole that passed the central meridian on 29 May can influence the geomagnetic field as of 2 June. Geomagnetic conditions are expected to remain quiet, though locally a brief active episode is possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 039, basierend auf 19 Stationen.
