    I find no Iridium, but within +-3 minutes and +-20 degrees, using Rob's
    SkyMap, I find 20 satellites not moving N or E. Some are very faint or
    slow. The most likely one is Jason 1, culminating in ENE at 80 degrees
    20:14:43 UTC-4.
    
    It intersected the line Vega-Deneb close to midway, at an angle of 80
    degrees, counting clockwise from Deneb.

    I have no personal experience with Jason 1, and have not searched at
    http://www.satobs.org/seesat/seesatindex.html for other comments.
