Solar Monitoring
Monitor the Sun with live solar imagery, radio blackout guidance, and short-range solar flare forecast data from NOAA SWPC. This page helps you track active regions, D-region absorption, and flare probabilities that can shape wider space weather conditions.
GOES SUVI
Real-time solar images from the Solar Ultraviolet Imager aboard NOAA's GOES satellites. Each wavelength reveals different layers and temperatures of the Sun's atmosphere.

GOES SUVI images are “quicklook” products — the latest available frame from the satellite, not a processed archive. Each wavelength channel shows different temperatures: 131Å highlights hot flare plasma (~10 million K), while 195Å reveals coronal loops and structures (~1.5 million K).
D-RAP is an operational product showing current radio absorption conditions. During a solar flare, increased X-ray flux ionizes the D-layer of the ionosphere, absorbing HF (3–30 MHz) radio waves passing through it.
Flare forecast probabilities are from the latest SWPC issuance, projected across three days. C-class flares are common and minor; M-class can cause brief radio blackouts; X-class are rare and can cause planet-wide disruptions.
