On 2023-04-15 I observed the JUICE spacecraft and the booster remotely using iTelescope.Net T11 (0.50-m f/6.8 reflector + CCD + f/4.5 focal reducer) in Utah Desert Remote Observatory, USA.

I measured the separation between them: about 19 arcminutes; the brightness of each of them was about +14 mag. This is a stacked image: 13x5 seconds.
