The Sun is the only star we can watch in detail — and it is worth watching, because it is not quiet. Filaments lift off, flares spike the X-ray flux in minutes, sunspot groups rotate into view and occasionally produce eruptions that reach Earth a day or two later. This page is a live window: current solar imagery plus the measurements that tell you what the Sun is doing right now.
What do the live solar images show?
The imagery comes from NASA’s Solar Dynamics Observatory, which photographs the Sun in several wavelengths every few seconds. Different wavelengths isolate different layers: the visible surface with sunspots, the chromosphere where filaments live, the corona at millions of degrees where loops and eruptions show. The board cycles the current frames so you see activity across layers, not a single flat image.
What does the X-ray flux graph mean?
GOES satellites measure the Sun’s X-ray output continuously — that is how flares are actually detected and classified. The classes run A, B, C, M, X, each letter ten times stronger than the last. A jump on the graph means a flare is happening at that moment; an M or X flare near the disk’s center is the kind that can matter for radio and, if it launches material our way, for geomagnetic conditions in a day or two.
How does this connect to auroras?
This page is the cause; the space-weather board is the effect. An eruption visible in the corona imagery, an X-flare spike, then — if the material is Earth-directed — elevated solar wind and a climbing Kp index a day later. Watching the Sun directly gives you the longest possible lead time.
Do you need any equipment to use it?
None. That is the point — professional solar telescopes and X-ray detectors, distilled into one page that loads on a phone.
