The Sun today. Sunspots, flares, and flux.

Live X-ray flux, flare classification, sunspots, CMEs, and SDO imagery in four wavelengths.

The Sun goes through an 11-year cycle of magnetic activity. This page tracks today's solar flares, sunspot regions, and X-ray flux from NOAA SWPC, plus live imagery from NASA's Solar Dynamics Observatory. Flares are graded A → B → C → M → X — each step ten times brighter than the last.

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).

LASCO C2 · Inner Corona
LASCO C2 · Inner Corona
SOHO LASCO C2 coronagraph (1.5–6 R☉). CMEs appear as bright expanding clouds moving outward from the occulted Sun.
LASCO C3 · Outer Corona
LASCO C3 · Outer Corona
SOHO LASCO C3 coronagraph (3.7–30 R☉). Wider field showing CMEs propagating into the heliosphere.
What this means
A CME is a billion-ton burst of magnetized plasma launched from the Sun's corona. Speed drives Earth-impact severity: ≥1000 km/s can trigger strong geomagnetic storms 1–3 days later. "Type" follows DONKI's classification (S → C → O → R, slow to extremely-fast). Halo-like half-angles facing Earth are the highest-risk events.

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.

Loading
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.
