Solar activity was at very low levels. Active region NOAA 2708 regained some sunspot area, while NOAA 2709 (Catania 81) was stable. 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 remain at very low levels.
Earth remained under the influence of the high speed stream (HSS) from an elongated negative polarity equatorial coronal hole (CH). Solar wind speed varied mostly between 620 and 700 km/s, and was at values near 620 km/s by the end of the period (DSCOVR). Bz varied between -6 and +5 nT. The interplanetary magnetic field was mostly directed towards the Sun. Geomagnetic activity ranged from quiet to active levels.
Quiet to unsettled geomagnetic conditions are expected, with a chance on an isolated active interval.
Today's estimated international sunspot number (ISN): 023, based on 22 stations.
