    A short time ago, I received word from the project that the spacecraft was in the nominal orbit after separation from
    the Zenit launcher.
    Also, I have quickly spot-checked the accuracy of my ephemerides against ones produced using JPL-Horizons, and found
    that mine are pretty close. Well within 0.01 deg cross-track, for a given time. We both used the official SPICE
    trajectory data, so we should be close, but my implementation has some compromises. So, if you have received a custom
    ephemeris from me, you can rely on it.
    Happy hunting!
