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 gradually decreased over the period from 460 to around 360 km/s (ACE). The Bz varied between -3 and +2 nT. During the first half of the period the interplanetary magnetic field was predominantly directed away from the Sun (positive sector) but switched to be mostly in the negative sector from 00:00 UT July 18 . Quiet to unsettled geomagnetic conditions were observed, with the Kp index (NOAA) ranging between 0-2 and the local K index (Dourbes) ranging between 0-3 over the past 24 hours.

Quiet geomagnetic conditions are expected with possible isolated unsettled intervals.
