Aktuální sluneční data:

Mezinárodní číslo slunečních skvrn : 023

Sluneční záblesky : C-class flares expected, (probability >=50%)
Geomagnetická situace : Active conditions expected (A>=20 or K=4)
Sluneční protony : Quiet

Komentář : There are 5 visible active regions on the solar disk, but none has produced C-class flares or higher in the past 24 hours. NOAA AR 2929 and 2930, that produced most of the activity in the last days, are rotating over the west limb, and the others are reducing in size and complexity. C-class flares can still be expected in the next 24 hours. No Earth directed CMEs have been observed in the last 24 hours. The greater than 10 MeV proton flux had exceeded the 10 pfu threshold yesterday, but it’s now back to values below the threshold. The greater than 2 MeV electron flux increased slightly above the 1000 pfu alert threshold and is expected to remain close to the threshold during the next 24 hours. The 24h electron fluence was at moderate levels and is expected to remain so in the next 24 hours. The solar wind speed at Earth decreased to about 420 km/s, and the interplanetary magnetic field around 4 nT. Slow solar wind conditions are expected for the next 24 hours. Geomagnetic conditions were quiet (K_Bel 0 - 2 and Kp 1 - 2). The CME from 18 January may arrive to the Earth in the coming 24 hours, increasing geomagnetic conditions to active or even minor storm levels.
