SUMMARY EXPLAINED
SUMMARY (Latest update 2013-05-25 16:35 CET)
Solar Activity Now
  • Solar cycle activity level below and on the solar surface is (near low max ).
  • Solar activity regions ( no ) and a CME ( no ) on the far side of the Sun are seen.
  • Solar activity regions on eastern limb are seen: ( no ).
  • Solar surface magnetic activity on Earthside is ( medium ).
  • Solar activity in the corona, (Earth-directed Coronal Mass Ejections; Major Solar Flares (last 24hr); Equatorial Coronal Holes):
    ( no; no; yes).
Effects of Solar Activity: (Now; Past 24hrs)
  • Proton storms, and herewith radiation hazards to astronautes, satellite problems,
    and navigation system problems: ( no; yes).
  • Radio blackouts, and herewith low frequency and HF communication problems: ( no; no ).
Forecasts of Effects of Solar Wind and Interplanetary Coronal Mass Ejections
  • Geomagnetic storms, (Kp >= 5 or Dst < -50 nT) and herewith problems for electrical systems such as power grid systems and gas piplines: (Forecasts of 3-hourly Kp-index and one-hourly Dst-index ).
  • Geomagnetically induced currents for one station in Southern Sweden: (30-minute forecasts of GIC).

Solar wind
Fast solar wind and large negative Bz value cause geomagnetic storms. The plot shows the deviation from the expected means of the three components (X, Y and Z) of the geomagnetic field
