This is a highly condensed video of the majority of the penumbral lunar eclipse that started late in the evening Nov 29, 2020 - https://youtu.be/G8ouTXypHLA.  Sweeping clouds throughout the evening made for challenging observing but the darkening with time is clearly seen.  Also, the film picked up the transit of a tumbling object which is examined in more detail around the four minute mark in the video.  If you have any ideas how to identify this object I'd love to hear them.

 

The video was shot with a C6 SCT/x0.63 focal reducer/533MC camera on an AVX mount.  The Sharpcap image was captured in OBS Studio where brightness and contrast correction was undertaken before the feed was both streamed and saved.  What you will view is a speeded up version of this real-time feed cropped for better presentation.

 

The real-time feed was one of two feeds provided by the San Diego Astronomy Association to timeanddate.com for their live coverage of the event.  The full-length video produced by timeanddate.com is available here - https://youtu.be/_NjREh2WE2c.

The size, shape, and speed of your unidentified transiting object is consistent with a balloon.  Interestingly, there was a balloon identified during a penumbral eclipse in 2017, and in this case it was able to be positively identified as part of the Google Loon project.  Link below.

In your case, the balloon is not quite so symmetrical, although if you search for other balloons that have been identified, many take on an oblate appearance depending on the particulars of the balloon, the conditions, and the perspective angle.  With some investigative work, it may be possible to identify this object if it was a balloon, but only if it happens to be one that is tracked by flight radar systems, such as the case in 2017.

That is certainly a possibility - we continue to try and identify the object without success.  I got excited when I saw the news reports relating to 2020 SO (Surveyor 2 Centaur rocket booster launched on 20 September 1966) and while the timing looks possible the transit speed seemed way to quick.  So I reached out to the NASA media contact, and they forwarded the video to CNEOS (Center for Near Earth Object Studies).  So, perhaps they will help identify it.
