From a press release of the SETI Institute, March 30, 2016:
The SETI Institute has inaugurated a greatly expanded hunt for deliberately produced radio signals that would indicate the presence of extraterrestrial intelligence. Over the course of the next two years, it will scrutinize the vicinities of 20,000 so-called red dwarf stars.
Red dwarfs are dimmer and cooler than the Sun, but they make up the bulk of stars in the Galaxy, increasing the odds of finding life there. They are also, on average, billions of years older than stars than Sun-like stars, so have had more time to potentially produce intelligent species.
The two-year search will be conducted at the Allen Telescope Array in the Cascade Mountains of northern California. This grouping of 42 antennas can currently observe three stars simultaneously.
