Bulletin

Solar activity was very low. The largest flare of the period were a B9.7 flare from around the East limb peaking at 01:09UT and a B5. The most prominent region NOAA AR 2505 showed signs of decay. Solar activity is expected to be quiet with a possibility for an isolated C flare. No Earth directed CMEs were recorded in coronagaph data. Earth was in slow solar wind conditions with velocity in the 340-390 km/s range and total magnetic field dropping back to nominal levels of 3-5 nT. The magnetic field Bz was variable and the phi angle mainly in the negative sector. Geomagnetic conditions were quiet (local K Dourbes and NOAA Kp between 0 and 2). Nominal solar wind conditions with associated quiet geomagnetic conditions are expected to continue. The possible influence of a weak high speed stream from the extensions of the Northern polar coronal hole may, from tomorrow onwards, slightly increase solar wind conditions leading to quiet to unsettled geomagnetic conditions.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 038, basierend auf 17 Stationen.
