Solar activity was at very low levels. There is no sunspots on the visible side of solar disk. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. Integral proton flux for protons with energies above 10 MeV remained at background level. Quiet flaring conditions are expected. The earth environment is currently under the influence of an extension of a positive polar coronal hole. Solar wind speed gradually increased from 310 to 410 km/s (DSCOVR). Total interplanetary magnetic filed (IMF) increased from 2 to 12.5 nT during the past 24 hours. Kp NOAA has reached minor storm levels now, while locally at Dourbes K reached only active levels (06-09UT). During the next time slot at 09-12UT planetary geomagnetic conditions decreased till active levels again. The solar wind speed growth seems to be stabilized now around 420 km/s. WSA-ENLIL model predicts further solar wind speed growth till 500 km/s later today. Growing variations of IMF Bz component observed by DSCOVR, including long intervals of negative values (down to -10 nT) stipulate disturbed geomagnetic conditions to be observed further, most likely till minor storm levels. Isolated episode of moderate geomagnetic storm is also possible.
