NASA's new flagship space telescope, the James Webb Space Telescope (JWST), will soon transmit its first official science images. These photos will be published on July 12th.

Excited about this, I noticed that I have not yet uploaded my Christmas Day observation to the sky watcher.

On Christmas day, there were two of us Unistellar network observers who detected this, the undersigned and Indian Himansu Mathur.

I was positively surprised when I received data from the Seti Institute about the observation of Christmas Day in the spring. JWST and the rocket stage are clearly visible.

I added a few pictures of the combined data from different days and the overall picture.

I couldn't find the exact time of my observation in my notes, but the clouds stuck in my mind when they stopped my observation.
