Radio Spectroscopy and Radio Observations of Comet ISON and 2P/Encke (July

- December 2013)
ABSTRACT: We propose to observe Comet ISON and Comet Encke in fall 2013. We will attempt to detect each with radar, although the geocentric distance is at the limit of feasibility. We will observe OH lines for each in order to determine the outflow velocity, and water production rates. Comet ISON will be very bright and observable for a long time at Arecibo, and we plan to also look for formaldehyde and methanol at C-band (5 GHz). These observations are coordinated with the GBT and LMT. Outreach Abstract: We are observing comets to learn about icy bodies in the solar system. Comet ISON will be very bright, and we can study the gases produced as the ice melts from the heat of the sun. This comet may be bright enough to see with the naked eye, perhaps even in the daytime. Comet Encke is the comet with the shortest period orbit known, and we will observe it and compare to similar observations made in 2003.
