Skrót wiadomości

Catania group 46 (NOAA active region 2673) continued to dominate solar activity. The largest flare was an M1.1 flare peaking at 13:53UT September 9. This region has currently reached the Western limb. Other regions on disk were stable or in decay while a new region has appeared from over the Eastern limb. As long as Catania group 46 has not fully disappeared over the Western limb, further M flares must be accounted for, with also a chance for an X flare remaining.

Associated to the M1.1 flare a CME was seen in coronagraph images. It is directed Westward and appears to be limited in angular extent and hence will not be influencing Earth.

The >10MeV proton flux has dropped below 1pfu during the period and is further approaching background values. Associated with the activity in Catania sunspot group 46 (NOAA region 2673), chances for renewed increases in proton fluxes remain, but are decreasing.

A positive polarity coronal hole in the northern hemisphere is starting to transit the central meridian and could influence solar wind conditions from September 13 onwards.

Solar wind conditions have been stable with solar wind speed around 550km/s, total magnetic field nominal at 4-5nT and Bz mostly positive. The slightly elevated solar wind speed is expected to persist over the next 24 hours and later decline towards nominal values. Geomagnetic conditions were quiet (local K Dourbes 0-2, NOAA Kp 0-1). Over the next days, quiet to unsettled geomagnetic conditions are expected.
