Bulletin

NOAA AR 2712 showed decay and is now a beta region again, but is has still produced several B flares in the past 24 hours. The brightest flare was a B7.7 flare peaking at 7:55 UT on June 3. The chance for a C flare in the next 24 hours is estimated at 25%, mainly from NOAA AR 2712.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

The solar wind speed as observed by DSCOVR fluctuated between about 570 km/s and 740 km/s, with current values around 700 km/s. The Interplanetary Magnetic Field (IMF) was predominantly directed towards the Sun, and its magnitude varied between about 1 and 8 nT, with current values around 3 nT. There were no extended periods with Bz smaller than -5 nT. Continued enhanced solar wind conditions are expected on June 3.

Quiet to active conditions (K Dourbes between 2 and 4; NOAA Kp between 1 and 4) were registered in the past 24 hours. Active geomagnetic levels (K Dourbes = 4) are possible on June 3 due to the ongoing effects of the high speed stream associated with an equatorial coronal hole, with a chance for minor storm intervals (K Dourbes = 5). On June 4 and 5, a return to quiet to unsettled geomagnetic levels is expected (K Dourbes < 4), with a chance for active intervals (K Dourbes = 4) in the first half of June 4.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 014, basierend auf 20 Stationen.
