Bulletin

Solar X-ray flux remained below B level throughout the period. There are no active regions on disk and chances for flaring at C level are very low.

No Earth directed Coronal Mass Ejections (CME's) have been observed in coronagraph data.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to remain so in the next 24 hours. The greater than 2 MeV electron flux has fallen quite suddenly and is currently below the 10^3 pfu event threshold. The electron flux is likely to reach over the threshold during the day but is overall recovering to background conditions over the next days.

Solar wind was in the slow regime but was marked by a transient magnetic feature. While Solar wind speed was in an overall decaying trend in the 380-320 km/s range, the magnetic field increased to over 10nT with periods of consistent orientation of the Bz. First negative (down to -9nT) and then positive later in the period. Solar wind conditions are expected to return to nominal.

Geomagnetic conditions reached active levels (NOAA Kp 4) while remaining unsettled locally (local K Dourbes 1-3). Geomagnetic conditions can first still reach unsettled levels, but should return to nominal quiet conditions.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 21 Stationen.
