Sluneční aktivita

24 h Shrnutí

Solar activity has been at low levels with only minor C-class flaring through the period. Regions near center disk are the largest and most magnetically complex and they have been the most active; Region 4070 (S12E24, Dai/beta-gamma), 4069 (S08W05, Dao/beta), and Region 4064 (N11W18, Eai/beta-gamma). All other regions have been stable. There have been no Earth-directed CMEs during the period.

Předpověď

Solar activity is expected to be moderate with a chance of M-class flares (R1-R2, Minor-Moderate) over 4-26 Apr.

Energetické částice

24 h Shrnutí

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

Předpověď

The greater than 2 MeV electron flux is likely to reach high levels over 24-25 Apr due to HSS influence. The greater than 10 MeV proton flux is expected to continue at background levels.

Solární bouře

24 h Shrnutí

Solar wind parameters continued to be slightly enhanced due to the HSS associated with the positive polarity CH in the southern hemisphere. Total field has been around 5 nT with a variable Bz component of +/-5 nT. Solar wind speeds have been decreasing from around 600 km/s at the start of the UTC day to near 500 km/s. The phi angle has been mostly positive.

Předpověď

Solar wind parameters are expected to continue to be influenced by positive polarity, CH HSS conditions through 25 Apr. Nominal conditions are expected thereafter.

Geoprostor

24 h Shrnutí

The geomagnetic field has been at quiet to unsettled levels.

Předpověď

The geomagnetic field is expected to remain at mostly unsettled levels with active conditions possible through 25 Apr. Quiet conditions are expected thereafter.
