Solar activity

24 h Summary

Solar activity remained very low and the visible disk was spotless. No Earth-directed CMEs were observed in available coronagraph imagery.

Forecast

Solar activity is expected to be very low all three days (17-19 Jan).

Energetic Particles

24 h Summary

The greater than 2 MeV electron flux was at normal levels and the greater than 10 MeV proton flux remained at background values.

Forecast

The greater than 2 MeV electron flux is anticipated to continue at normal levels and the greater than 10 MeV proton flux is expected to remain at background levels all three days (17-19 Jan).

Solar Wind

24 h Summary

Solar wind parameters were indicative of a slow, but mildly disturbed environment. Total IMF strength was steady at mainly 4 to 5 nT, before an increase to 7nT after 16/1800 UTC. The Bz component underwent primarily weak deviations until about 16/1800 UTC, when it turned mainly southward. Solar wind speed averaged between 350-400 km/s. The phi angle was predominantly negative.

Forecast

A primarily slow solar wind regime is expected to continue all three days (17-19 Jan).

Geospace

24 h Summary

The geomagnetic field was mostly quiet, with an isolated unsettled period at the end of the day.

Forecast

The geomagnetic field is expected to remain mostly quiet, with possible isolated unsettled periods, all three days (17-19 Jan).
