Bülletään

There are no sunspot regions on the visible hemisphere of the Sun and flaring level is very low. The chance for a C flare in the next 24 hours is estimated at 5%. No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. Solar wind speed measured by DSCOVR was between about 520 and 670 km/s in the past 24 hours, with current values around 570 km/s. The Interplanetary Magnetic Field (IMF) was directed towards the Sun and its magnitude varied between about 2 and 8 nT. Bz was never below -5.5 nT. This enhanced solar wind is indicative of a negative coronal hole high speed stream. Quiet to active geomagnetic conditions (K Dourbes between 2 and 4; NOAA Kp between 2 and 5) were registered in the past 24 hours. Quiet to active levels (K Dourbes < 5) are possible on February 19, 20 and 21 due to the influence of the high speed stream associated with a negative coronal hole, with a chance for minor storm conditions (K Dourbes = 5).
