Bulletin

No C flares were observed in the past 24 hours. There is a chance for C flares in the next 24 hours, especially from new beta region NOAA AR 2621. Solar wind speed is still under the influence of a positive coronal hole high speed stream, and decreased from about 660 to 560 km/s in the past 24 hours as measured by DSCOVR. The magnitude of the Interplanetary Magnetic Field (IMF) varied between about 2 and 6 nT. A gradual decrease in solar wind speed is expected over the next days as the influence of the high speed stream wanes. Quiet to active geomagnetic conditions (K Dourbes between 2 and 4; NOAA Kp between 2 and 4) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on December 27, 28 and 29, with a slight chance for active intervals (K Dourbes = 4) on December 27 and 28.

Today's estimated international sunspot number (ISN): 023, based on 22 stations.
