May 4 obs- revision and additions.....

Using newer elset provided by Mike, 22583 running 30 to 40 secs early.

Mag 1.5 and very quick, W to E near Zenith......
Using the old elset I was too early in observing and only saw it
almost eight minutes later as I was setting up the camera for Iridium
24 t.  I did not get a "good" time, only an estimate based on its
passage just north of Castor & Pollux while counting secs to NIST.

Iridium 24 t -max's, brighter at first then dimming successively.
M's from 3.5 to 5.5
