Bulletin

A handful of C flares have occurred over the last 24 hours originating from the Catania groups 42, 43, 47 (NOAA AR 2055, 2056, 2058 respectively) in the eastern hemisphere. The strongest one from Catania group 47 (NOAA AR 2058) peaking at 4:43 at C6.4 level. Some C level flaring activity is expected to continue with chances for M level flares. Between about 2 UT and 5 UT solar wind speed has increased from around 360 km/s to around 410 km/s. It has meanwhile fluctuated in the 380 km/s to 440 km/s range. Total magnetic field has increased over the period with maxima around 8.5 nT, but is presently slightly lower again around 7.5nT. Bz has been variable in the -7.8nT to +7.8nT range. These increased solar wind parameters are expected to persist for a further day under the influence of a coronal hole high speed stream. Geomagnetic conditions have been mostly unsettled but have reached active levels after midnight (both local K Dourbes and NOAA Kp reached 4). Geomagnetic conditions are expected to remain unsettled with possible active periods under the influence of the high speed stream.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 096, basierend auf 08 Stationen.
