The observations above are two points from the video I shot. They refer to the
leading bright object in the train.

They were not measured with Tangra (the software I usually use for astrometry on
my video observations) as that got too confused by so many bright objects.
Rather, I stacked a number of frames and measured them manually in AstroRecord.

The points above hence might be less accurate than my data usually are.

Below is a *VERY CAUTIOUS* orbit estimate, based on adjusting my initial search
elset (http://www.satobs.org/seesat/May-2019/0193.html) to the two datapoints,
mainly by finding a matching Mean Motion and inclination:
