Other Optical SETI Observatories and Web sites:
Date: Thu, 10 Sep 1998 04:10:04 -0700 (PDT) From: Dan Werthimer <danw@ssl.berkeley.edu> Message-Id: <199809101110.EAA23741@albert.ssl.berkeley.edu> To: skingsle@postbox.acs.ohio-state.edu Subject: Re: OSETI X-UIDL: 5533d77ef269478a0a6162a7c6d3b24c Hi Stuart, We just put a crude page on our web site about optical SETI last week - url is seti.ssl.berkeley.edu It's not nearly as sophisticated as your page. Paul is also working on something (see link to his page from ours) and has a better site. I built a pulse detector a couple of years ago using a pair of 0.6 nS rise time PMT's, a pair of GHz bandwidth amps and ECL discriminators and ECL coincidence logic. The system worked fine, but I never had time to make very many observations - I just tested the system out, and then put it away. I'm hoping to set up an observational program here, along the lines of what you've been doing. There are also several people at the SETI Institute working group who are interested in optical (Charlie Townes and I worked to persuade them this was worth looking into). They are writing a report, which will come out in book form, probably at the end of 1999. John Billingham and I have suggested that you would make an excellent reviewer of the section on optical SETI (most of it's radio, but there will be a chapter on optical), and everyone agreed that you would be best. Charlie's address is cht@ssl.berkeley.edu How is your search going? Happy hunting! Best wishes, Dan

We've both put up little web pages, (nothing like yours!!), and they both have links to yours. Ours is at mc.harvard.edu/hgroup.html, and you can get to Dan's through it. The page is far from finished, but it does mention your pioneering interest in several places, besides the link. It might be worth putting links on your excellent website, since I'm sure lots of people go there... Good luck finding THEM! Paul Horowitz
Date: Tue, 15 Sep 1998 To: Paul Horowitz <horowitz@physics.harvard.edu> Subject: Re: optical seti Cc: LKlaes@zoomtel.com Dear Paul, Nice to hear from you. I think this must be our first communication,which is strange considering the 8 years I have been at this game. I have made a quick scan of your OSETI PDF paper and think it looks excellent. As usual, I come out always the most optimistic as to potential ETI EIRPs - thus making it easier for amateurs to detect such signals! I will give your paper a more detailed review after Rosh Hashanah. When I have more time I will probably write some comments about the paper for my web site and put in suitable links. Over the winter I plan to return to my web site and continue the upload of more archival materials. The interest in OSETI from Australians is quite substantial. You are probably aware that I am planning a speaking tour of Australia next July or August. Glad to see that you too think daylight OSETI is possible with professional telescopes. Now I might ask you the question "What took you so long to realize that perhaps dividing the bandwidth into smaller and smaller bins, ala BETA, perhaps was not the best way to go? Regards, Stuart

Hi Stuart, Well, I guess the absence of signals is a powerful incentive to try something different! PS The pdf paper is taken a lot from the stuff I wrote for SI, and I will add a comment to that effect on the website; so maybe you can make that comment if you extract stuff from it...
