Abstract

We present results from two radio and two optical SETI programs at the University of California, Berkeley: The SERENDIP IV sky survey searches for narrow band radio signals at the 305 meter Arecibo Observatory in Puerto Rico. The program uses a 168 million channel spectrum analyser, running in 'piggyback' mode, using a dedicated receiver to take data 24 hours a day, year round. SETIhome is Berkeley's most recent SETI project. SETIhome uses desktop computers of over a million volunteers to analyse 40 Terabytes of data from Arecibo Observatory. SETIhome is the largest supercomputer on the planet, currently averaging 20 Teraflops. The SEVENDIP optical program searches for nS timescale pulses at visible wavelengths. The target list includes nearby F,G,K and M stars, plus a few globular cluster and galaxies. The pulse search utilizes Berkeley's 30 inch automated telescope at Leuschner Observatory. Another Berkeley optical SETI program searches for narrow band coherent signals in high resolution stellar spectra taken by Marcy and his colleagues as part of their on-going search for planets at Lick, Keck, and the Anglo-Australian observatories.
