How about old OCs?
Hank — (archived)

Have you considered looking at old open clusters as a means of maximizing your chances of picking up a signal? I suggest you peruse the abstract at

http://adsabs.harvard.edu/abs/2003Ap&SS.284.1087D

an article which is cited in Tartar/Turnbull II.

The only two professional monographs I know of which treat this topic
are the R & C De La Fuente Marcos "Seti in Star Clusters: A
Theoretical Approach" (Astrophysics and Space Science 284: 1087-1096,
2003) and the M. Turnbull/J. Tartar "Target Selection for SETI II:
Tycho-2 Dwarfs, Old Open Clusters, and the Nearest 100 Stars" (ApJ
Supplement Series, 149:423-436, 2003 Dec).

I also wrote a popular treatment of this strategy in 1995 ("The Seti Potential of Open Star Clusters"; SETIQuest Vol I no 4) where I list 32 open clusters with ages exceeding a billion years as possible targets.

Also, what frequencies do you listen to?
