Asteroid 7 iris at opposition mid january 2022.
Currently at peak brightness at magnitude 7.7

Above image consists of 50 individual frames of 1 minute each, stacked together. When doing this al stationary objects (the stars in the image) remain at exactly the same position in each of the 50 images and therefore remain a point source of light. If an object creates a line instead of a point, this object is moving. The line in the image shows the actual movement of the asteroid 7 Iris currenlty visible in the constellation Gemini during a period of 50 minutes.

The included animated GIF shows the actual movement in an animation created from several images each taken 10 minutes apart.
