Bulletin

In the past 24 hours, no C flares were observed. Very low solar activity (no C flares) is expected in the next 24 hours. Solar wind speed measured by DSCOVR decreased from about 700 to 660 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between about 3 and 7 nT. Quiet to active geomagnetic conditions (K Dourbes between 2 and 4; NOAA Kp between 3 and 4) were registered in the past 24 hours. Active levels (K Dourbes = 4) are possible on May 21 and 22, with a chance for minor storm intervals (K Dourbes = 5). Quiet to unsettled conditions are expected on May 23, with a chance for active intervals.

Today's estimated international sunspot number (ISN): 031, based on 22 stations.
