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 increased further to current values of about 720 km/s. Meanwhile the magnitude of the Interplanetary Magnetic Field has varied between 5 and 14 nT. Bz was below -5 nT between 14:15 and 15:00 UT on March 21, and fluctuated a lot in the rest of the period. Quiet to minor storm conditions (K Dourbes between 2 and 5; NOAA Kp between 3 and 5) were registered in the past 24 hours due to the enhanced solar wind conditions caused by the passage of a high speed stream from a positive coronal hole. The minor geomagnetic storm intervals occurred between 15h and 21h UT. Continued influence from the high speed stream is expected on March 22 and 23, with quiet to active geomagnetic levels (K Dourbes < 5) and a chance for minor geomagnetic storm intervals (K Dourbes = 5). On March 24, active periods (K Dourbes = 4) are possible as waning high speed stream influence is expected.
