Solar activity

24 h Summary
Solar activity was very low. Region 2727 (N01W29, Bxo/beta) exhibited slow decay throughout this period and no Earth-directed CMEs were observed in available coronagraph imagery.
Forecast
Solar activity is expected to continue at very low levels throughout the forecast period (17-19 Nov).

Energetic Particles

24 h Summary
The greater than 2 MeV electron flux reached high levels with a peak flux of 1,220 pfu observed at 16/1835 UTC. The greater than 10 MeV proton flux was steady at background levels.
Forecast
The greater than 2 MeV electron flux is expected to reach high levels each of the next three days (17-19 Nov) and the greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Solar Wind

24 h Summary
Solar wind parameters were at background levels throughout the period under a nominal solar wind regime.
Forecast
A weak solar wind enhancement is likely on 18-19 Nov due to the influence of a negative polarity CH HSS.

Geospace

24 h Summary
The geomagnetic field was quiet under a nominal solar wind regime.
Forecast
Quiet conditions are expected to prevail on 17 Nov with quiet to unsettled levels likely on 18-19 Nov in response to negative polarity CH HSS influence.
Current data suggest that it is not possible to see aurora now at middle latitudes
