There were five C flares on the Sun during the past 24 hours, the large majority being released by NOAA AR 11928. The brightest one was a C8.4 flare from NOAA AR 11936 peaking at 17:28 UT on December 23. In the next 48 hours, the probability for C flares is high (around 80%) and for M flares around 40%, mainly from NOAA AR 11928 and 11936. There is a slight chance for an X flare. In the past 24 hours, solar wind speed decreased from around 310 km/s to around 280 km/s and the magnitude of the Interplanetary Magnetic Field varied between 1.5 and 4 nT, as observed by ACE. Current geomagnetic conditions are quiet (K Dourbes between 0 and 2; NOAA Kp between 0 and 1) and are expected to remain so on December 24 and in the first half of December 25. In the second half of December 25, geomagnetic conditions may become active (K Dourbes = 4) due to the arrival of a coronal hole high speed stream with estimated velocity between 450 and 500 km/s. Quiet to active geomagnetic conditions (K Dourbes < 5) are expected on December 26, as the coronal hole high speed stream effects continue.
Today's estimated international sunspot number (ISN): 076, based on 06 stations.
