 Solar flares
are seen as bright regions in images observed by AIA onboard SDO.
The intense electromagnetic radiation causes low frequency and HF communication problems.
|
|  X-ray flux
X class X-ray solar flares are strong flares.
|
|  Coronal mass ejections ("CMEs")
are seen as large plasma clouds in coronagraph images observed by LASCO onboard SOHO.
The small white circle shows the size of the solar disk.
The energetic protons accelerated by CMEs create "snow" on the images.
Proton storms are associated with radiation hazards to astronautes, satellite and navigation problems.
Fast Earth directed CMEs can also cause problem for electrical systems.
|
|  Proton flux
A proton event occurs when 10 protons/cm2-s-sr at >= 10 MeV stay for at least 15 min.
|
|
Geomagnetic storms
occur when the Kp indexet is greater och equal to 5.
Strong geomagnetic storms can cause problems for electrical systems.
The green bar shows our forecast based on real-time ACE data (Bz, n, V).
