Sonnenaktivität

24h Zusammenfassung

Solar activity was at low levels with mostly Regions 4403 (N15W12, Hsx/alpha) and 4405 (S27E18, Esi/beta-gamma) contributing to low level C-class activity. While Regions 4399 (S16W52, Hsx/alpha), 4401 (N25W57, Hax/alpha), 4402 (N19W41, Hrx/alpha) and 4403 decayed during the day, there was an increase of the magnetic complexity of the Regions 4403 and 4405. There are currently 10 numbered sunspot regions on the disk. One of the largest flares was a C1.5 peaking at 31/0055 UTC from Region 4403, associated with a Type-II burst and a narrow eruption first observed at the coronagraph imagery (LASCO/C2) around 31/0200 UTC. No component of this eruption is expected to impact the near-Earth environment. No Earth-directed CMEs were observed during the period.

Vorhersage

Solar activity is likely to reach moderate levels with R1-R2 (Minor-Moderate) flaring, with slight chance for X-class flares through 03 Apr, due to the complexity and evolution of the active regions currently on the solar disk, particularly Regions 4405 and 4403.

Energiereiche Teilchen

24h Zusammenfassung

Electrons greater than 2 MeV at geosynchronous orbit reached high levels with a peak flux of 1,380 pfu at 31/1600 UTC. The greater than 10 MeV proton flux at geosynchronous orbit remained at background levels during the period.

Vorhersage

The greater than 2 MeV electron flux is likely to be reach high levels on 01-02 Apr and return to moderate to normal levels on 03 Apr. There is a slight chance for the greater than 10 MeV proton flux to exceed S1 (Minor) solar radiation storm levels through 03 Apr due to the X1.4 flare at 30/0319 UTC and anticipated arrival of its associated CME alongside the complexity and evolution of the active regions currently on the solar disk.

Sonnenwind

24h Zusammenfassung

Solar wind parameters were near nominal levels with solar wind speed showing a gradual decline to about 400 km/s by the end of the period, while total interplanetary magnetic field (Bt) remained near 5 nT. The North-South component (Bz) was between +/-5 nT and the phi angle was in the positive (away from the Sun) orientation for most of the period. Transients disturbances were observed in the solar wind parameters around 31/2200 UTC, while suprathermal ions and electron fluxes observed at L1 continued to increase and were likely caused by the anticipated CME from 30 Mar.

Vorhersage

Enhanced solar wind disturbances are likely on 01 Apr due to the passage of the 30 Mar CME. CME-associated solar wind conditions are likely to give way to CH HSS activity on 02-03 Apr.

Geospace

24h Zusammenfassung

The geomagnetic activity has been at quiet to unsettled levels for the past 24 hours.

Vorhersage

The geomagnetic field is likely to reach G2 (Moderate) storming levels on 01 Apr with periods of G1 (minor) storming likely on 02 Apr due to effects from the CME associated with the 30 Mar X1.4 major flare event. Unsettled to active geomagnetic levels are anticipated on 03 Apr due to the waning CME effects associated with a CH HSS conditions.
