St. Lawrence astronomers had the opportunity to remotely operate the Arecibo Radio Telescope from Bewkes Hall for the first time on February 5, 2011. The observing run is part of the Arecibo Legacy Fast ALFA (ALFALFA) survey, an on-going blind survey of extragalactic neutral hydrogen (HI). The survey uses the largest single dish radio telescope in the world, the 305-meter (1000-ft.) dish at the Arecibo Observatory, in Arecibo, Puerto Rico. When the survey is completed, ALFALFA will have detected more than 25,000 extragalactic HI line sources out to z~0.06.
