Bulletin

Solar activity was at very low levels. The Sun remains spotless and no significant flares have been recorded. No Earth directed coronal mass ejections (CMEs) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at very low levels.

The solar wind decreased from 390 to 320 km/s (DSCOVR). Bz varied between -3 and +3 nT. The interplanetary magnetic field was predominantly directed away the Sun (positive sector). Quiet geomagnetic conditions were observed with the Kp index (NOAA) ranging between 0-1.

Quiet geomagnetic are expected on June 23 and 24. Unsettled to active conditions are then expected on June 25 due to the influence of the high speed stream associated with the two negative coronal holes which began to transverse the central meridian on June 21.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 000, basierend auf 17 Stationen.
