Bulletin

Solar activity was very low. No C flares were observed in the past 24 hours. Solar activity is expected to remain very low (no C flaring) for the next 24 hours. A filament eruption occurred near 25E 15N around 1:00 UT on November 9, with an associated bright CME registered by LASCO C2 around 1:25 UT. The CME is directed towards the NNE and extends from NE to E, with an estimated speed of 933 km/s, obtained by geometrical modelling from LASCO C2, C3 and STEREO COR2 A images. There is a chance for a glancing blow from this CME on November 11. A small shock in the solar wind was registered by DSCOVR at 5:43 UT on November 9. Solar wind speed jumped from about 300 to 330 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) jumped from about 4.5 to 7.5 nT. Proton density jumped from about 12 to 25 particles per cc. This is probably due to the arrival of the November 5 CME. Current solar wind speed is about 340 km/s and current IMF is about 6 nT. Quiet to unsettled geomagnetic conditions (K Dourbes between 0 and 3; NOAA Kp between 0 and 2) were registered in the past 24 hours. Due to the arrival of the CME of November 5, active conditions (K Dourbes = 4) are possible on November 9, with a slight chance for minor storm conditions (K Dourbes = 5). On November 10 and 11, active to moderate storm conditions (K Dourbes between 4 and 6) are possible due to the expected arrival of a negative coronal hole high speed stream.

Today's estimated international sunspot number (ISN): 000, based on 09 stations.
