COMMENT: 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.
TODAY'S ESTIMATED ISN : 120, BASED ON 17 STATIONS.
