Bulletin
Three C-class flares were observed, all originating from NOAA 2217. The strongest was a C2.8 flare peaking at 18:09UT (24 November). The other five sunspot regions were quiet. No Earth directed CMEs were observed. More C-class flares are expected, with a small chance on an isolated M-class flare. Solar wind was at nominal values, with wind speed mostly between 350 and 400 km/s, and Bz between -6 and +4 nT. The IMF is directed away from the Sun. The geomagnetic field was quiet to unsettled (K<4), and is expected to remain so.
