About this image

These are images of the JWST spacecraft (2021-130A) and the Ariane upper stage (2021-130B) taken last night. They are currently around 2 deg apart on the sky. JWST is much brighter tonight and the huge sunshield was being deployed. The magnitude was 14.3 at a range of 687,000 km. I think that the sunshield was half out when this image was taken but this implies a magnitude of around 16 or so at L2.

Have you submitted astrometry of the Ariane? How bright was it?

We would like as good an orbit as possible so it has a good chance of being recovered in 2047 on its next close approach.

Most anyone with a camera can reach 16 mag if they could be bothered. I've seen images showing 19th-magnitude Cepheids in M31 which were taken with a 80mm refractor.
