What this means

GOES X-ray flux is graded A → B → C → M → X (each step = 10× brighter). A/B = quiet background; C = minor; M = moderate (radio blackouts on Earth's dayside); X = major (strong blackouts, possible CME).

NASA SDO · Live Imagery

Solar Dynamics Observatory — refreshed every ~10 min.

Visible · Sunspots — HMI Continuum — visible-light photosphere showing sunspot groups.

Magnetogram — HMI line-of-sight magnetic field — black/white pairs mark active regions.

Corona · 193 Å — AIA 193 Å — million-degree corona, coronal holes, and flare loops.

Flare · 131 Å — AIA 131 Å — flaring plasma at ~10 million K. Best view of active flares.

What this means

Each wavelength shows the Sun at a different temperature. Visible = photosphere surface; magnetogram = magnetic field; 193 Å = ~1M K corona; 131 Å = ~10M K flaring plasma.

What this means

Region listing reflects the most recent NOAA daily synoptic. Area in millionths of the solar hemisphere; class follows the McIntosh / Mt. Wilson schemes. More spots and complex magnetic class = higher flare probability.
