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. Solar wind speed measured by DSCOVR varied between about 290 and 330 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between about 1 and 7 nT. A sector boundary change from + to - was observed around 6:45 UT on November 7, with only slight enhancements of the solar wind speed and magnitude of the IMF. Quiet to unsettled geomagnetic conditions (K Dourbes between 1 and 3; NOAA Kp between 1 and 2) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on November 7 and the first half of November 8. Due to the expected arrival of the CME of November 5, active to moderate storm conditions (K Dourbes between 4 and 6) are possible in the second half of November 8 and on November 9. On November 10, active to moderate storm conditions are possible due to the expected arrival of a negative coronal hole high speed stream.

Today's estimated international sunspot number (ISN): 011, based on 12 stations.
