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. Over the past 24 hours, solar wind speed measured by DSCOVR varied between about 530 and 750 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) ranged between about 1 and 11 nT. Bz was never below -5 nT. Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 3) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on March 24, with a chance for active (K Dourbes = 4) intervals. Quiet to unsettled geomagnetic conditions (K Dourbes < 4) are expected on March 25 and 26.
