    IGS 1B is now really difficult at my latitude ;-(
    On May 7 I had a (predicted) pass through zenith when Sun was at -4.45
    degrees, and couldn't find it, just Venus.
    With SatEvo-computed elset at CalSky for July 22, a pass at the same
    solar altitude will be at 10 degrees in the W !
    (actually that pass would be on Jul.26 - on Jul.22 a 56 deg W pass
    could be with Sun at -3.1 deg)
    A zenithal pass would occur with Sun at -2.5 degrees.
