    Below are the objects I've seen *without* magnification the last two 
    nights from outside the building where I work, on the campus of the 
    University of Texas at Austin (30.286N, 97.739W, 150m), which is in 
    the middle of the city.  (In the winter, given my work schedule, on 
    weeknights I can't get to a better observing site in time to see 
    LEOs.)
    
    Obviously this is not an awfully bright city center, and these were 
    moonless evenings with a very clear sky, so the limiting magnitude 
    may be about +4.0.  But I was on a pedestrian bridge above a street, 
    with streetlights and walkway lights, some passing vehicle lights, 
    the brightly illuminated UT Austin tower, white building walls, 
    etc.,  nearby.  So perhaps they may serve for newcomers to satellite 
    observing as a fair example of what can be seen just for fun from an 
    urban setting on a very good evening.  Given similar conditions, one 
    can show objects like these to family, friends, neighbors, or even
    passers-by.  On each of these evenings, I possibly missed one or two 
    that I might have seen if I had not been paying close attention to 
    another one.  Add a pair of binoculars or observe without 
    magnification from a dark site on a moonless night, and these 
    numbers can be doubled (tripled?) easily.  (Maybe I should get a 
    pair of binoculars to use on campus....)  Monday evening I also saw 
    two meteors (one about +2, one about +3.5) while observing these 
    satellites.  
    
    The observations are in chronological order.  Where I say "with 
    such-and-such", I mean that they were in the sky at the same time, 
    not necessarily that I could see them both at once.

    I hope in a while -- with binoculars, at least -- to see Intelsat 
    512 (16101, 85-087A), a brightly flashing drifting geosynch like
    Superbird A, and possibly another one or two.
