    On 2004 Oct 12 UTC (Monday PM October 11 UTC -5:00) at BCRC 
    (30.315N, 97.866W, 280m) I recorded the following geosats 
    as being visible with 8x42 binoculars (Times are UTC.):

    Some of them aren't very bright (for 8x binocular), say +7.0 
    or maybe fainter, so a really good night is necessary to see 
    those.  Much of the time two or even three are visible at 
    once in the eight degree field of view of the 8x42.  At least 
    some of the ones that flare three hours early and fade out 
    also flare again later at shadow entry.  
    Saw a few Tuesday evening, but it was partly cloudy and the 
    session ended somewhat early.  Wednesday evening was cloudy.  
    The flaring can't last much longer here.
    Coincidentally to the contrail observation, Astro Pic of the
    Day had many contrails over Georgia, Alabama, and northern
    Florida imaged from far above, plus a link to this good 
    contrail resource:
    Obviously the ones that are mistaken for fireballs are short
    contrails with extreme solar illumination, sometimes reddened
    by sunrise or sunset.  The one I saw Monday evening was a
    short one, going nearly straight down in the west, and very
    brightly illuminated.  Some months ago I saw a very bright 
    reddish one.
