Bulletin

Eight C-class and one M-class flares were observed in the past period. The activity, including an M2.0 flare peaking at 00:59 UT, was mainly originating from Catania sunspot region 79 (NOAA active region 2360). Also Catania regions 87, 85 and 81 (NOAA AR 2367, 2365 and 2362 respectively) were contributing. More C-class flares are expected, with likely an isolated M-class flare. As Catania region 79 is close to the west limb, we set a warning condition for an enhancement of the proton flux. A filament in the northeast quadrant partly erupted at around 7:00 UT. Current coronagraphic images only indicate a very narrow accompanying CME (first measurement in LASCO/C2 at 7:24 UT) travelling to the north. No Earth-directed CME was observed.

The magnitude of the interplanetary magnetic field (IMF) started at 5 nT, but became more variable from 20 UT on June 13 with values in the range 5-12 nT. The solar wind speed slightly increased from the range of 440-520 km/s to currently 580 km/s. Geomagnetic conditions were quiet (K=2) to unsettled (K=3), with a few time slots this UT morning of active (K=4) levels. A few more time slots of active levels are expected for the next day.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 071, basierend auf 12 Stationen.
