This from Angel, WP3GW, via the ARRL PR mailing list:
After the huge success of the first activation, the Arecibo Observatory Radio Club – KP4AO will be on-the-air again this next Sunday November 1st, 2009 to commemorate 46 years of operations of still the single largest radio telescope antenna in the world. Also they will commemorate the 35th anniversary of the Arecibo Message, which was sent on November 16, 1974,in binary code and transmitted to the globular star cluster M13, for if it is received by intelligent life, to let them know about our existence. “We had a such a great response that we had more than 100 hams operating the station in the Control Room taking turns”, said Angel Vazquez – WP3R who works in the Observatory.
The special event will start at 9am-4pm local time (1300 – 2000 UTC) and will be on 20 meters SSB. There will be certificates for those who make contact as well for operators. This is an activity for the whole Amateur Radio Community, so if you are near, or visiting the island you are invited. (Don’t forget your ham license! It’s your free pass). KP4AO will be operated inside the Control Room, and the Visitor Center entrance will be half price.
The Arecibo Observatory, located in the city of Arecibo, Puerto Rico is a radio telescope operated by Cornell University under cooperative agreement with the National Science Foundation (NSF) and works as the National Astronomy and Ionosphere Center (NAIC). From it many studies and discoveries from the cosmos has been made by Nobel-Prize winners,as well made studies of the atmosphere and even used in the SETI program.

Sounds like fun to me. I just wish I could get down there to actually operate the station.
