Bulletin

There are currently no sunspots groups on the visible hemisphere of the Sun. 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 varied between about 300 and 330 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between about 1 and 5 nT. Quiet geomagnetic conditions (K Dourbes between 0 and 2; NOAA Kp between 0 and 1) were registered in the past 24 hours. Quiet to active levels (K Dourbes < 5) are possible on March 20, 21 and 22, with a chance for minor geomagnetic storm intervals (K Dourbes = 5), due to the expected arrival of a high speed stream from a positive equatorial coronal hole in the second half of March 20.

Today's estimated international sunspot number (ISN): 000, based on 10 stations.
