GOES X-Ray Flux
Solar X-ray flux — shows solar flare activity. Dotted line = event threshold.
Solar Wind (ACE/RTSW)
3-day ACE solar wind magnetic field and speed.
Solar Wind (DSCOVR)
DSCOVR solar wind data.
KP Index (Geomagnetic Activity)
Global geomagnetic activity index.
GOES Magnetometer
GOES satellite magnetometer data.
GOES Proton Flux
High energy proton bombardment. Dotted line = Level 1 radiation storm baseline. Each level up = higher storm.
GOES Electron Flux
High energy electron bombardment. Radiation storm levels when Red/Blue curves cross the hashed line.
Aurora Forecast — Northern Hemisphere
NOAA 30-minute aurora forecast, northern hemisphere.
Aurora Forecast — Southern Hemisphere
NOAA 30-minute aurora forecast, southern hemisphere.
Ionospheric Map (Global HF)
Critical frequency of the F2 ionospheric layer.
Storm-Time Corrections
Ionospheric disruptions. Quiet periods = smooth flat lines.
Relativistic Electron Fluence
Forecasted and observed high energy electron bombardment in near-earth space.
