Solar activity was at very low levels. Active region NOAA 2708 is decaying fast and is barely visible. A new sunspot region has rounded the east limb (Catania 81; Location: N06E71), but it is small and -so far- inactive. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels.

Solar activity is expected to be at very low levels, with a slight chance on an isolated C-class flare.

Earth is under the influence of the high speed stream (HSS) from an elongated negative polarity equatorial coronal hole (CH). Solar wind speed varied in a slightly declining band between 700 and 560 km/s (DSCOVR). Bz varied between -8 and +7 nT. The interplanetary magnetic field was mostly directed towards the Sun. Geomagnetic activity was at quiet to unsettled levels, with an isolated active episode recorded by Dourbes during the 15-18UT interval.

Quiet to unsettled geomagnetic conditions are expected, with a chance on an isolated active interval.
