Thanks for the post Keith.  I examined the elset I posted recently
and it was about 30 seconds early.  That coincides with me using a
launch time that was early by 30 seconds.   The elset above is within
about 5 seconds for the upper satellites separation.

Eastern US and Canada will have the first opportunity to see the four
payloads..then western Europe
