INFO FROM SIDC – RWC BELGIUM 2014 Nov 24 12:16:19

Five low-level C-class flares were observed over the last 24 hours. The largest was a C4.1 peaking at 11:04UT in NOAA 2217, which was also the source of 3 other C2 flares. One of these peaked on 23 November at 16:14UT and was associated to a non-Earth directed CME, first visible in LASCO at 16:24UT. NOAA 2216 produced the remaining C2 flare. The other regions were quiet, with NOAA 2209 still maintaining a weak delta spot in its trailing portion. More C-class flares are expected, with a chance on an isolated M-class flare. The IMF is directed away from the Sun, with Bz varying between -7 and +4 nT. Solar wind speed varied between 470 and 360 km/s and is currently near 400 km/s. The geomagnetic field was quiet to unsettled (K<3), and is expected to remain so, with an isolated active period possible.
