Thanks Bjorn,

I just looked at Spot 3 and it was a nice sight.  There appears to be
a 9.1 sec period between the bright flashes with perhaps two dimmer
maxima inbetween. After watching a bit in binocs, I looked visually
but before I could put on my glasses, I saw a flash that MAY have been
magnitude 0. (will not bet on it but it was bright).  That time it was
about az 45, elevation 45 at about 10:25 PM local on & Aug (0425 UT/
8 Aug 97).  Subsequent flashes were dimmer.
