Zonneactiviteit

Samenvatting afgelopen 24h
The visible disk remained spotless and solar activity remained very low. No Earth-directed CMEs were observed in coronagraph imagery available at this time.
Voorspelling
No active regions are expected to return or emerge during the forecast period, keeping solar activity at very low levels.

Energetische deeltjes

Samenvatting afgelopen 24h
Flux at geosynchronous orbit of electrons greater than 2 MeV remained at normal to moderate levels. Flux of 10 MeV protons at geosynchronous orbit remained at background levels.
Voorspelling
Flux at geosynchronous orbit of electrons greater than 2 MeV is expected to remain at normal to moderate levels. Flux of 10 MeV protons at geosynchronous orbit is expected to remain at background levels.

Zonnewind

Samenvatting afgelopen 24h
The solar wind field, measured at L1, remained quiescent. Wind speed averaged near 380 km/s and phi was in a predominantly negative orientation. Total field strength was less than 10 nT, while the Bz component dipped to -6 nT during the period, but was generally positive.
Voorspelling
The solar wind environment is expected to be at nominal levels on 16-18 Jan. Isolated weak enhancements on 16-17 Jan could occur as sporadic, weak connections to the negative polarity coronal holes in the southern hemisphere are possible.

Geospace

Samenvatting afgelopen 24h
The geomagnetic field reached unsettled levels for the first period (00-03 UTC), but was mostly quiet thereafter.
Voorspelling
The geomagnetic field is expected to remain at quiet to unsettled levels for the forecast period (16-18 Jan).
