Just a minor correction:  Project Phoenix observed some stars as far
about 200 light years away.

Applying such a limit would be more of a PR exercise than good

given the low detectability of most leaked signals.  However I

believe

all targetted searches limit themselves to around 100 light years, so
are working at that sort of order of magnitude of range.  The general
aim is to cover all plausible stars that are close to us.

The SETI Institute's

Project Phoenix is the main targetted radio frequency

search.

As the SETI Institute people and other professionals that frequent
USENET are normally monitoring only sci.astro.seti of that and this
group, I have cross-posted the reply.

distance from earth (taking in to account return signal
time.) Just on the off chance someone out there is listening.
