Bulletin

Flaring activity remained well below the C-class level during the period. NOAA 2603 was stable, with another small sunspot region developing at N09W45. 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 decreased from an initial 700 km/s to its current value just below 600 km/s. Bz varied between -5 and +4 nT, being mostly negative. The interplanetary magnetic field (IMF) was directed away from the Sun (positive). Kp ranged from unsettled conditions to moderate geomagnetic storming, while K Dourbes ranged from quiet conditions to minor storming.

Wind speeds are expected to remain above 500 km/s for probably another day, with periods of sustained negative Bz possible. Hence, quiet to minor storm conditions are expected, with still a small chance on an isolated moderate storming interval.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 026, basierend auf 14 Stationen.
