Hi John,

What you actually saw was not Lacrosse 3 but Lacrosse 3 R/B -- the
rocket body
that put Lacrosse 3 in orbit.  From your location it did indeed have a
close conjunction
with Deneb at 23:11:55 EDT July 21 (3:11:55 UTC, 22 July).  Soon after,
it began to
enter the earth's shadow, and while still in the earth's penumbra,
Cosmos 1190 R/B
(80056B) crossed its path moving SE to NE.  Cosmos 1190 R/B would have
been
noticeably dimmer than Lacrosse 3 R/B, shining at about mag 4.9.  --Rob
