Bulletin

Solar flaring activity reached moderate levels with an M1.2 flare originating from Catania group 46 (NOAA region 2673) peaking at 05:49UT. This region grew very fast over the last 24 hours and has developed significant complexity with mixed polarity in the intermediate spots. Meanwhile, Catania group 47 (NOAA region 2674) seems to have become less active but remains large and with significant flaring potential. Flaring is expected to continue to occur from both regions with especially Catania group 46 contributing to a significant probability for M flaring. Overall we estimate that C flaring will occur over the next 24 hours and that there is a very significant chance for M flares (45%). No Earth directed CMEs have been observed in coronagraph data. Solar Proton flux levels are at background values and are expected to remain so.

Solar wind speed continued a slow overall decline from around 500 km/s to around 470 km/s. Total magnetic field was in the nominal 3-6nT range with Bz variable and the phi angle mostly in the positive sector. Solar wind is expected to further recover to nominal conditions over the next days. Geomagnetic conditions were quiet to active (local K Dourbes 1-3, NOAA Kp 2-4) and are expected to remain quiet to unsettled over the next days.

Dnešní odhadovaný mezinárodní počet slunečních skvrn (ISN): 120, na základě 17 stanic.
