Zonneactiviteit

Samenvatting afgelopen 24h

Solar activity was at very low levels. Region 2797 (S18E22, Hax/alpha) was stable and inactive. Region 2798 (S16E34, Cao/beta) produced numerous B-class flares, but was otherwise stable. A filament eruption in the SE quadrant, observed between about 20/2000-2100 UTC resulted in a slow-moving CME off the ESE limb, first visible in LASCO C2 imagery at about 20/2124 UTC. Analysis, and subsequent model run output, suggested there was no Earth-directed component.

Voorspelling

Solar activity is expected to remain at very low levels, with a chance for C-class activity, on 22-24 Jan.

Energetische deeltjes

Samenvatting afgelopen 24h

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

Voorspelling

The greater than 2 MeV electron flux is expected to be at normal to moderate levels while the greater than 10 MeV proton flux is expected to persist at background levels.

Zonnewind

Samenvatting afgelopen 24h

Solar wind parameters were at nominal levels. Total magnetic field strength was at or below 5 nT while the Bz component varied between +/-2 nT. Wind speed averaged around 310 km/s. Phi began the period in a negative orientation, but became variable after about 21/1520 UTC.

Voorspelling

A nominal solar wind environment is expected for the next three days (22-24 Jan).

Geospace

Samenvatting afgelopen 24h

The geomagnetic field was quiet.

Voorspelling

Mostly quiet conditions are anticipated through for 22-24 Jan.
