Bülletään

Solar activity was at very low levels. There is no sunspots on the visible side of solar disk. Narrow and slow coronal mass ejections (CMEs) observed in coronagraphic imagery are not geoeffective. Integral proton flux for protons with energies above 10 MeV decreased from around 0.8 pfu till nominal 0.3 pfu over the past 24 hours. Quiet flaring conditions are expected to continue. The earth environment is currently under the influence of a positive polar coronal hole. Solar wind speed increased from 430 to 580 km/s (DSCOVR) over the past 24 hours and is expected to grow more. Total interplanetary magnetic filed is below 11 nT, while Bz component was varying between -10 and 9 nT over the past 24 hours, being mainly negative. The geomagnetic field is ranged from active to minor storm levels during the past 24 hours (Planetary NOAA Kp: 4-5; local K index at Dourbes: 2-5). Active to moderate geomagnetic conditions are expected to continue for next three days.
