    I believe you saw the russian APT (propellant tank), which indeed is in a
    highly eccentric orbit of about 5h period, near perigee at your latitude at
    about 300 km height.
    Though I didn't yet update my old elset , it fits quite well, but descending
    more to the NNE after 50 deg altitude.
