Bulletin

Solar activity was low to moderate with the most prominent region on disk Catania group 62 (NOAA region 2443) producing several high level C class flares as well as an M flare (peak 17:52UT). Flux emergence was recorded in the trailing part of Catania group 59 (NOAA 2442) and East of Catania group 60 (NOAA 2441). Catania Group 62 (NOAA 2443) maintains its complex beta-gamma-delta configuration and displays further development. More M class flares can be expected from this region. No Earth directed CME's were recorded. The proton fluxes have recovered near background levels. Solar wind conditions were nominal. Solar wind speed was in the 330-380 km/s range with the total magnetic field mainly in the 5-8 nT range but with peaks to 9 and 10 nT. Bz was variable with a peak down to -7.5 nT. The magnetic field phi angle was stable in the negative sector. Geomagnetic conditions were quiet to unsettled (local K Dourbes 0-3, NOAA Kp 1-3). Solar wind conditions are expected to remain nominal over the first 24 hours but to increase afterwards with the expected arrival of a recurrent equatorial coronal hole high speed stream. In the previous rotation the coronal hole caused solar wind speeds of over 800 km/s and associated major geomagnetic storms. A similar level of activity can be expected during this passage.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 090, basierend auf 19 Stationen.
