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 decreased from about 570 to 495 km/s, while the magnitude of the Interplanetary Magnetic Field (IMF) ranged between about 1 and 5 nT. This is indicative of a transition to nominal solar wind conditions after the passage of the high speed stream from a positive coronal hole. Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 0 and 2) were registered in the past 24 hours. Quiet to unsettled geomagnetic conditions (K Dourbes < 4) are expected on March 25 and 26. The arrival of a high speed stream from a large, recurrent coronal hole is expected on March 27. Consequently, active geomagnetic conditions (K Dourbes = 4) are possible, with a chance for minor geomagnetic storm intervals (K Dourbes = 5).
