I have just completed calculating times and az/el look angles for =
viewing the ATEx tether after it is deployed on 14 Jan 99.  It's our =
hope that the upper and lower end masses and the tether itself will be =
viewable with binoculars.  You can find the times at =
http://home.att.net/~spetch/Stex

The NRO's Space Technology Satellite (STEX) is the host vehicle for the =
Naval Research Lab's Advanced Tether Experiment (ATEx).  On 14 Jan 99, =
ATEx will deploy and upper end mass on the end of a 6 kilometer tether.  =
Active tether control experiments will commence for about 2 months, =
after which the tether will be jettisoned and remain in orbit.

Don't despair if you don't have any viewing opportunities at your =
location.  The tethered pair will remain in orbit for at least a year.  =
As the orbit's sun angle changes, more opportunities will become =
available. I'll try to update the page as frequently as I can.  If you =
have any requests for look-angles from locations other than those on the =
web page, send the lat/long of your site to spetched@nro.mil, and I'll =
do my best.
