Solar Activity

24 h Summary
Solar activity was very low. The visible disk was spotless. No Earth-directed CMEs were observed in available coronagraph imagery.
Forecast
Solar activity is expected to be at very low levels for the next three days (24-26 Nov).

Energetic Particles

24 h Summary
The greater than 2 MeV electron flux was at moderate to high levels with a peak flux of 4,658 pfu observed at 23/1555 UTC. The greater than 10 MeV proton flux remained at background values.
Forecast
The greater than 2 MeV electron flux is expected to be at moderate to high levels for the next three days (24-26 Nov) due to CH HSS influences. The greater than 10 MeV proton flux is expected to continue at background levels all three days.

Solar Wind

24 h Summary
Solar wind parameters continued to decline towards nominal levels today. Solar wind speed decreased from approximately 485 km/s to near 380 km/s by the periods end. Total field ranged from 1-6 nT while the Bz component was between +3/-4 nT. Phi angle was oriented in a mostly positive (away) solar sector.
Forecast
Solar wind parameters are expected to be at nominal levels over the next three days (24-26 Nov).

Geospace

24 h Summary
The geomagnetic field was at quiet to unsettled levels.
Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on day one (24 Nov). Mostly quiet levels are expected on days two and three (25-26 Nov) under a nominal solar wind environment.
Current data suggest that it is not possible to see aurora now at middle latitudes
