I have observations for Vesta, Metis and Amphitrite and have just noticed that they are marked as unobserved in my observation list and I am sure that I have observed and recorded them. I checked LiveSky and sure enough they are there. It appears that for at least these three objects, their identifiers have been mixed up with some satellites. For example:
Vesta is showing as 2021-022AB
Metis is showing as SHIYAN 6 03 (SY-6 03)
Amphitrite is showing as METOP-C
I am wondering if a mistake has been made in your database whereby the satellites now have the primary key of asteroids?
