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

The solar wind speed varied between 315 and 370 km/s (ACE). The Bz varied between -4 and +3 nT. The interplanetary magnetic field was predominantly directed away from the Sun (positive sector). Quiet to unsettled geomagnetic conditions were observed, with the Kp index (NOAA) ranging between 1-2 and the local K index (Dourbes) ranging between 0-3 over the past 24 hours.

Quiet geomagnetic conditions are expected to continue for July 21 and 22 with unsettled conditions on July 23 due to the influence of the solar wind stream originating from the extension of the southern polar coronal hole, which traversed the central meridian on July 19.
