Solar activity was at very low levels. There were no numbered sunspots on the solar disc and no significant flares were detected in the last 24 hours. The flaring activity is expected to remain low in the next 24 hours.

No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours and is expected to remain so in the next 24 hours. The greater than 2MeV electron flux remained under the 1000 pfu threshold and is expected to remain so in the next 48 hours. The 24h electron fluence was at normal levels and is expected to remain so in the next 48 hours.

Over the past 24 hours the solar wind conditions (ACE and DSCOVR) were enhanced under the ongoing influence of a HSS related to a patchy positive polarity coronal hole. The total magnetic field varied between 2.4 nT an 7.5 nT, while the Bz component oscillated between -7.3 nT and 6.1 nT. The phi angle remained predominantly in the positive sector. The solar wind speed started around 400 km/s and sporadically increased to 518 km/s.

The geomagnetic conditions over the past 24 hours were predominantly quiet with an isolated 3-hour long period of globally and locally unsettled conditions. Quiet to unsettled conditions are expected for the next 24 hours. Isolated active periods remain possible as the influence of the coronal hole HSS wanes.
