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 has increased from about 310 to 400 km/s in the past 24 hours, while the magnitude of the Interplanetary Magnetic Field (IMF) varied between about 3 and 14 nT. This is probably due to the arrival of a high speed stream from a positive equatorial coronal hole. The Bz component is fluctuating heavily and reached a lowest value of about -10 nT for a very short time. Solar wind speed is expected to increase further within the next 24 hours. Late on May 16, a glancing blow from the partial halo CME of May 13 may enhance solar wind conditions further. Quiet to active geomagnetic conditions (K Dourbes between 0 and 4; NOAA Kp between 1 and 4) were registered in the past 24 hours. Due to the arrival of the high speed stream, quiet to active levels (K Dourbes < 5) are possible on May 15, 16 and 17, with a chance for minor geomagnetic storm intervals (K Dourbes = 5).
