SETI@home II - Piggyback Observations at Parkes? ------------------------------------------------ SETI@home has been observing continuously at Arecibo for the last 15 months, carrying out a SETI sky survey with a dedicated 21 cm feed, simultaneous with ongoing observations. In 2001 and 2002 we'd like to extend the SETI@home sky survey to the southern hemisphere by collecting data from Parkes, recording data during multibeam HI and pulsar surveys. Tapes would be sent to Berkeley and then distributed via the Internet to roughly one million SETI@home participants who analyze the data with a screen saver program, searching for narrow-band continuous and pulsed signals. The SETI@home data recorder would record a 2.5 MHz band from 13 beams simultaneously utilizing ~4 DLT tape drives. We'd likely tap data off from Southern Serendip; we'd need space for a 19 inch equipment rack, about 1 KW, and a telescope operator or someone who could change tapes every 6 hours or so, and mail us a monthly package of tapes. In all we'd record about 1000 tapes. The survey is nicely orthogonal to the current Southern Serendip sky survey: SETI@home II would cover a small band, centered at 1420 MHz, but with 10 times better sensitivity and 15 octaves of frequency and time resolution. ------------------------------------------------------- Dan Werthimer Space Sciences Laboratory SETI@home chief scientist Grizzly Peak Blvd. MS7450 SERENDIP project director University of Calfornia Berkeley, CA 94720-7450 danw@ssl.berkeley.edu phone: 510-642-6997 http://seti.berkeley.edu fax: 510-643-2624 -------------------------------------------------------
