Zonneactiviteit

Samenvatting afgelopen 24h
Solar activity was very low. Region 2759 (N27E10, Hrx/alpha) remained stable and inactive. No Earth-directed CMEs were observed in available satellite imagery.
Voorspelling
Solar activity is expected to remain at very low levels on 04-06 Apr.

Energetische deeltjes

Samenvatting afgelopen 24h
The greater than 2 MeV electron flux reached high levels with a peak flux of 1,140 pfu at 03/1650 UTC. The greater than 10 MeV proton flux maintained background levels.
Voorspelling
The greater than 2 MeV electron flux is expected to reach high levels on 04 Apr and moderate levels on Apr 05-06. The greater than 10 MeV proton flux is expected to continue at background levels.

Zonnewind

Samenvatting afgelopen 24h
Solar wind parameters, as measured by the DSCOVR spacecraft, reflected mostly nominal conditions. Total magnetic field strength was at 5-6 nT through most of the day. The Bz component briefly reached as far south as -5 nT. Solar wind speeds fluctuated between ~380-450 km/s. Phi angle was primarily oriented in the negative sector.
Voorspelling
The solar wind field is expected to be near nominal levels on 04 and 06 Apr. A weak enhancement from a positive polarity CH HSS is likely on 05 Apr.

Geospace

Samenvatting afgelopen 24h
The geomagnetic field was at quiet to unsettled levels until 03/2359 UTC, when an isolated active period was observed.
Voorspelling
Isolated active conditions are possible early on 04 Apr due to waning CH HSS influence. Quiet to unsettled conditions are expected on 05 Apr with generally quiet conditions expected on 06 Apr.
