Regarding Observation 2359809 …
Puzzled by this one! Look at the polar plot!
I believe this kind of thing occurs when there has been a TLE update between when the observation was scheduled, and when the observation occurred.
There are situations where the TLEs for a particular sat can get quite a few days out of date before they are updated by Space-Track, resulting in this kind of issue.
Looks like it is rapidly de-orbiting, according to its twitter feed.
Thanks for noting 1-KUNS-PF is de-orbiting, I’ve changed its status to re-entered in DB.
