Päikese aktiivsus

24 h summaarne

Solar activity was at low levels due to weak C-class flare activity from Regions 4401 (N25W20, Eai/beta), 4404 (N14E39, Hsx/alpha) and 4405 (S27E52, Eao/beta-gamma). New Region 4408 (N09E72, Hsx/alpha) was numbered this period. No significant changes were noticed in the spotted regions. No Earth-directed CMEs were observed in available coronagraph imagery.

Ennustus

Solar activity is expected to be low with a high chance (50%) for M-class flares (R1-R2/Minor-Moderate radio blackouts) through 31 Mar.

Energeetilised osakesed

24 h summaarne

Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1,600 pfu at 28/1900 UTC. The greater than 10 MeV proton flux remained at background levels.

Ennustus

The greater than 2 MeV electron flux is expected to continue to reach high levels through 29 Mar before returning to normal to moderate levels on 30-31 Mar. The greater than 10 MeV proton flux is expected to continue at background levels.

Päikese tuul

24 h summaarne

Solar wind parameters reflected a mostly nominal regime until approximately 28/2020 UTC when a weak enhancement in the IMF began. Total field increased to 7 nT and the Bz component underwent a southward deflection reaching -7 nT. Solar wind speeds were primarily under 400 km/s. Phi was predominantly in a negative solar sector, but became variable post enhancement.

Ennustus

Enhancements from recurrent, positive polarity CH HSS influences are anticipated to begin by late 29 Mar and persist through 30 Mar.

Georuum

24 h summaarne

The geomagnetic field was at quiet to active levels.

Ennustus

Quiet to active levels are expected on 29 Mar. G1 (Minor) geomagnetic storming is likely on 30 Mar due to recurrent positive polarity CH HSS effects. Unsettled to active conditions are then expected to persist into 31 Mar.
