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 has gradually increased from about 320 km/s around 21h UT on March 20 to a peak near 570 km/s around 10h UT on March 21, with current values around 520 km/s. In the same period, the magnitude of the Interplanetary Magnetic Field has risen from about 5 nT to a maximum of 18 nT around 7:20 UT on March 21, with current levels around 10 nT. Bz was below -10 nT between about 5:45 and 6:20 UT on March 20, and has fluctuated a lot outside of this interval. The enhanced solar wind conditions are expected to continue on March 21 and 22. Quiet to active geomagnetic conditions (K Dourbes between 1 and 4; NOAA Kp between 0 and 4) were registered in the past 24 hours. Due to the enhanced solar wind conditions by the passage of a high speed stream from a positive coronal hole, quiet to active levels (K Dourbes < 5) are expected on March 21, 22 and 23, with a chance for minor geomagnetic storm intervals (K Dourbes = 5).
