Zonneactiviteit

Samenvatting afgelopen 24h

Solar activity was very low. New Region 2814 (S24E17, Bxo/beta) was numbered and was inactive. A CME was observed off the East limb associated with an eruptive prominence. Analysis determined the CME was not Earth-directed. No other CMEs of significance were observed.

Voorspelling

Solar activity is expected to be very low over 12-14 Apr.

Energetische deeltjes

Samenvatting afgelopen 24h

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

Voorspelling

The greater than 2 MeV electron flux is expected to be normal to moderate over 12-14 Apr and the greater than 10 MeV proton flux is expected to persist at background levels throughout the forecast period.

Zonnewind

Samenvatting afgelopen 24h

Solar wind parameters were at background levels. Wind speeds averaged ~350 km/s. Total field strength values were between 1-7 nT, and Bz was between +4/-5 nT. The phi angle was negative.

Voorspelling

Solar wind parameters are expected to become slightly enhanced on 14 Apr due to positive polarity CH HSS influence.

Geospace

Samenvatting afgelopen 24h

The geomagnetic field was quiet.

Voorspelling

The geomagnetic field is expected to be mostly quiet on 12-13 Apr. Quiet to unsettled conditions are expected on 14 Apr due to positive polarity CH HSS influence.
