About ASTVYR

ASTVYR shows the Sun, space weather around Earth, meteors, the planets, and observatories.

A change on the Sun is a shift in brightness between two pictures of the same view. The score says how strong the shift is. It does not name an object.

The Kp index describes how disturbed Earth's magnetic field is. The X-ray reading describes how bright the Sun is in X-rays. Both are ordinary measurements of known activity.

Test pictures used to check the tools are not shown on these pages.
