Visibility I / V
The JWST James Webb Space Telescope is currently stationary at the L2 point, aligning its mirrors, and its apparent motion relative to the stars is distinguished in this animation exposed for 30x90s = 45 minutes. The apparent motion of the JWST with respect to the stars is mainly due to the annual orbit of the Earth (= observer) L2 point in its orbit around the sun, the daily rotation of the Earth (= observer) and the motion of the JWST around the L2 point.
The brightness measured from the JWST image is mag 15.86. It is clearly, up to 1.5 magnitude brighter than the January observations.
The animation also shows the motion of two dim asteroids in the lower right quarter of the image. The upper and slightly brighter of these is the asteroid (50872) 2000 GT10, with a brightness mag of 18.49 measured from its image. The lower is (20883) Gervais, measured brightness mag 19.07.
