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.
