Most of the observation during the period from 2018-01-12T9:42 UTC to 2018-01-12T10:45 UTC were performed with wrong TLEs.
We are still investigating what happened but as the same thing happened also in our dev instance and also we didn’t make any change recently on the production network code, we suspect that for a sort period we were getting wrong TLEs from celestrak when we asked for individual satellite TLEs.
