Solar activity was very low. No C flares were observed in the past 24 hours. Solar activity is expected to remain very low (no C flaring) for the next 24 hours. Solar wind speed measured by DSCOVR rose gradually from about 390 to about 720 km/s after the arrival of a coronal hole high speed stream around 0h UT on September 20. Meanwhile the magnitude of the Interplanetary Magnetic Field increased from about 10 nT to a maximum of about 21 nT around 20:30 UT on September 19, and decreased again to current values around 5 nT. Bz was predominantly positive, but was mainly below -5 nT between 23h and 1h UT. Quiet to unsettled geomagnetic conditions (K Dourbes < 4) prevailed on September 19. K Dourbes values reached up to 4 and Kp values up to 5 during the first half of September 20. There is a chance for minor storm levels (K Dourbes = 5) on September 20 under the influence of the coronal hole high speed stream. Quiet to unsettled levels are expected on September 21 and 22, with a chance for active levels (K Dourbes = 4) on September 21 as the influence of the high speed stream wanes.
