    It was moving to the SSW, the times were when my daughter first spotted it and I stopped observing through binoculars as it was getting towards the horizon (it was somewhat hazy, but clear sky).
    The times are approximate.
    It was moving at a speed relative to a LEO, roughly 750-1000km in altitude. Not as fast as ISS or HST, but about the speed of a Cosmos rocket body in polar orbit or NOSS sats.
    No tracks on Calsky matched up with the bird. Due to the haze, it was hard to gauge the period due in part also to the different magnitudes with which it was appearing.  I went down to Mag 8 on Calsky, with nothing relative to it's location.
    My daughter spotted it with the naked eye, and it was then confirmed by my brother who was with us. It was overhead and to the WSW at about 80 degrees altitude as they spotted it moving SSW at 11:24ET/0324Z last Saturday night/Sunday morning.
    I kept making sure it was not an airplane. No strobes, contrails, changes in direction, etc.
    It passed between Cygnus and Pegasus.
    I appreciate the effort.
