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. In the past 24 hours, solar wind speed observed by DSCOVR varied between about 630 and 770 km/s, under the influence of a high speed stream associated with a negative coronal hole. The magnitude of the Interplanetary Magnetic Field (IMF) gradually rose from about 6 to 9 nT and gradually decreased again to current levels of about 5 nT. No extended periods of negative Bz were registered. Quiet to active conditions (K Dourbes between 2 and 4; NOAA Kp between 3 and 4) were registered in the past 24 hours. Active conditions (K Dourbes = 4) are possible on November 13, 14 and 15, with a slight chance for minor storm conditions (K Dourbes = 5).

Today's estimated international sunspot number (ISN): 038, based on 10 stations.
