Bulletin

NOAA active region 2205 produced another M flare (M2.3) peaking at 15:32 UT as well as another handful of C flares. The CME corresponding to yesterdays filament eruption is confirmed to be non Earth directed. Flaring at M level is expected to continue from region 2205, while old region 2192 is about to rotate back onto the disc. With NOAA AR rotating onto the western hemisphere chances for a proton event are increasing. Solar wind total magnetic field experienced a jump around 1:30 UT, increasing suddenly from around 10 nT to around 24 nT. Bz was mostly positive after the jump but had peaks to below -8nT and there was an extended period of -8nT yesterday late before the shock. Solar wind speed increased from levels around 440 km/s to levels around 480 km/s with peaks over 550 km/s. Also density and temperature saw a slight increase. This thus marks the earlier than expected arrival of the November 7 CME. Total magnetic field has meanwhile decreased again to levels near 13 nT. Geomagnetic conditions were quiet to unsettled, reaching active levels with the shock arrival. Fluctuating solar wind conditions may last for the remainder of the day with possible periods of active geomagnetic conditions.
