    I was at the Ney Museum site early.  I was scanning the area 
    of Bootes, Corona, Serpens Caput and Hercules in the twilight, 
    trying to get my bearings, when I saw a close pair of 
    southeast-bound satellites in the field of view of my 8x42 
    binoculars.  Below are my unfortunately very rough clicks.  
    Given it was still twilight, with the Sun down only about ten 
    degrees, I was not able to see faint stars.  A few minutes 
    later when I was trying to ID stars, there were cirrus clouds 
    in the way.  The date and times are 16 June 2007.
    
    01  -----  2:18:51.2  leader passing unknown bright star?
    02   4.28  2:18:55.5  very late mark of follower past star?
    03    .25  2:18:55.7  not sure why I clicked here
    04  18.96  2:19:14.7  bright star passage (maybe two deg.)
    05   1.85  2:19:16.5  follower, same star
    06  27.25  2:19:43.8  bright star passage (maybe two deg.)
    07    .82  2:19:44.6  follower, same star (note below)
    08  31.13  2:20:15.7  bright star passage 
    09   2.10  2:20:17.8  follower, same star
    10  86.40  2:21:44.2  star 20 Oph & flare to magnitude zero
    11   2.16  2:21:46.4  follower pass 20 Oph & flare to zero
    12  53.23  2:22:39.6  4 degrees left of Jupiter
    13   1.85  2:22:41.5  follower
    14  41.38  2:23:22.8  6 degrees below Jupiter
    15    .71  2:23:23.6  follower, very belated click, afterthought
    
    The star 20 Oph is RA 16:49:49, Dec -10.8 (2000).  The pair of
    satellites passed below and left of the star, less than .25
    degree from it, direction down and right of course.
    
    Note: I think that click 06 was very late, rather than click 07 
    being early.
    
    For the last two pairs of observations I was facing Jupiter,
    approximately azimuth 140.  I could not see stars there so 
    just tried to estimate passages directly left of and below 
    Jupiter, based on the 8-degree field of view of my binoculars.
    
    I'm embarrassed at the roughness of the data, but the sky was
    bright with some cirrus clouds, and I get somewhat flustered
    about this sort of thing.
    
    A few minutes later I was not able to find the NOSS 2-3 objects.
    
    I came home after the very nice pass of USA 193, which was 
    partly obscured by a band of cirrus.
    
    Oh, aside from when they were flaring, I will guess that the 
    two satellites were +4.5, but they probably were brightening
    as they went from east to southeast, until after they passed
    20 Oph.
    
    Ney Museum site: 30.307N, 97.727W, 150m.
    
    Thanks very much to Mike for the suggestion to look early, and 
    due to some good luck I saw them even though they were earlier 
    than that!
