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.
