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. An expected high speed stream from a negative coronal hole arrived at the Earth around 3h UT on November 12, with solar wind speed observed by DSCOVR gradually rising from about 440 km/s to about 650 km/s. In the past 24 hours, the magnitude of the Interplanetary Magnetic Field (IMF) gradually rose from about 10 to 16 nT and gradually decreased again to current levels of about 8 nT. No extended periods of negative Bz were registered. Quiet to unsettled conditions (K Dourbes between 1 and 3; NOAA Kp between 2 and 4) were registered in the past 24 hours. Active to minor storm conditions (K Dourbes = 4 to 5) are possible on November 12 and 13, with a slight chance for moderate storm conditions (K Dourbes = 6). Active conditions (K Dourbes = 4) are possible on November 14, with a slight chance for minor storm conditions (K Dourbes = 5).

Today's estimated international sunspot number (ISN): 012, based on 19 stations.
