Bulletin

A B2 flare peaking at 23:05UT was most likely associated with an eruptive event from NOAA 2603 from behind the northwest solar limb. The related CME was not earth-directed. NOAA 2604 (Catania 50) is decaying, while old active region NOAA 2599 is rounding the southeast limb, currently as a spotless faculae area. No earth-directed coronal mass ejections (CMEs) were observed.

Quiet flaring conditions are expected to continue, with a small chance on an isolated C-class flare.

Earth remained under the influence of the high speed stream (HSS) from the huge coronal hole (CH). Solar wind speed ranged from 550 to 670 km/s (DSCOVR), and is currently hovering around 550 km/s (ACE). Bz oscillated mostly between -6 and +6 nT. The interplanetary magnetic field (IMF) was directed away from the Sun (positive). Kp ranged from unsettled to active conditions, while K Dourbes ranged from quiet to unsettled conditions.

The geo-environment is expected to remain under the gradually weakening influence of the CH HSS. Quiet to active conditions are expected.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 013, basierend auf 19 Stationen.
