Abstract:
---------

There are now a large number of space based observatories as well as
several queue-scheduled ground based observatories. As each new
telescope is brought on line, astronomers find more ways to increase
their scientific return through multiwavelength campaigns between the
available observatories.

Observers can and should be involved in the coordination process from
the beginning. They need to be informed about the issues, understand
their true requirements and stay in touch with the involved
observatories, but this is not always sufficient. Starting in 1995 the
schedulers for several missions (HST, XTE, EUVE, ASCA, VLA) began
contacting each other directly to plan campaigns in a way that truly
met the goals of the observers. This was very beneficial because
different observatories have different scheduling constraints and
sometimes different names for the same constraints. An example of a
scheduling challenge is coordinating telescopes in low earth orbit.
Many have very similar orbits and if the goal is to maximize the
overlap time between observatories, this requires comparing the orbits
of the spacecrafts and finding times when the target visibility and
South Atlantic Anomaly passages are approximately in phase. As the
number of tightly coupled observations increases, it would make sense
to investigate automating comparison of viewing opportunities.

New innovations in observatory coordination include trading telescope
time (as Chandra and HST have) so that one observatory can award
coordinated time between two telescopes. The past, current and future
process will be discussed along with feedback from successful
observers and advice to the potential observer.
