Hi all,

The launch of ZUMA has been postponed to 17 November (16 November local time in
California) between 00:55 - 03:37 UT.

Based on Ted's recent elset estimates for the original launch date here:

http://www.satobs.org/seesat/Nov-2017/0055.html

...I provide the following orbit estimates, for various launch times, for the
three orbit variants given by Ted.


For a 319 x 412 km orbit (based on USA 276):
