Solar activity remained at very low levels. The only active region NOAA 2783 (Hsx/alpha) observed on the solar disk around S23E48 was quiet and did not produce any flaring above B class in the last 24 hours. The solar activity is expected to remain very low with slight changes for a C class flare. No Earth-directed coronal mass ejections (CMEs) were detected in the available coronagraph imagery. A filament has formed on the solar disk to the west from active region NOAA 2783. Its evolution will be monitored.

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 2 MeV electron flux remained under the 1000 pfu threshold and is expected to remain so. The 24h electron fluence was at nominal levels and is expected to remain so for the next 24 hours.

Solar wind speed remained very slow with fluctuating around 300 km/s (ACE and DSCOVR). The total magnetic field was very weak with a maximal strength of 6.3 nT. The Bz component varied between -4 nT and +3 nT. The phi angle remained predominantly in the positive sector.

Geomagnetic activity was globally quiet with locally unsettled conditions since 9 UT this morning. The geomagnetic activity is expected to remain quiet to unsettled within the next 24 hours and unsettled to active conditions after with the possible arrival of an enhanced solar wind stream related to the positive polarity coronal hole CH 97.
