Solar activity was at very low levels. The solar disk remains spotless with no significant flares in the last 24 hours. The solar activity is expected to remain very low. 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 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.

Solar wind speed remained very slow with highest value of 319 km/s (ACE and DSCOVR). The total magnetic field was very weak with a strength of < 4.5 nT. The Bz component varied between -4 nT and +3 nT.

Geomagnetic activity was quiet and is expected to remain so within the next 48. A small positive-polarity coronal hole was observed today close to the central meridian. The high-speed stream from it might induce unsettled to active conditions starting from Nov. 20th.
