Abstract

We present ground-based optical observations of the 2009 September and 2010 January transits of HD 80606b. Based on three partial light curves of the 2009 September event, we derive a midtransit time of T_c [HJD] = 2455099.196 ± 0.026, which is about 1σ away from the previously predicted time. We observed the 2010 January event from nine different locations, with most phases of the transit being observed by at least three different teams. We determine a midtransit time of Tc [HJD] = 2455210.6502 ± 0.0064, which is within 1.3σ of the time derived from a Spitzer observation of the same event.

We thank John Caldwell, Steve Odewahn (McDonald Observatory, TX, USA), James Otto, Ohad Shemmer (Monroe Observatory, TX, USA), and Anthony Ayiomamitis (Hellenic Astronomical Union, Greece) for their attempt to observe HD 80606 during the Jan10 event, although they were unable to do so due to bad weather. This paper uses observations obtained with facilities of the Las Cumbres Observatory Global Telescope. The MONET network is funded by the Alfried Krupp von Bohlen und Halbach-Stiftung. RHO observations were supported by the University of Florida and the College of Liberal Arts and Sciences. K.D.C. is supported by an NSF Graduate Research Fellowship. This material is based upon work supported by the National Science Foundation under grant No. 0707203. This work is partially based on observations made with the Gran Telescopio Canarias (GTC), installed in the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias, on the island of La Palma. The GTC is a joint initiative of Spain (led by the Instituto de Astrofísica de Canarias), the University of Florida and Mexico, including the Instituto de Astronomía de la Universidad Nacional Autónoma de México (IA-UNAM) and Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE). K.D.C., H.J.D., and E.B.F. gratefully acknowledge the observing staff at the GTC and give a special thanks to René Rutten, José Miguel González, Jordi Cepa Nogué, and Daniel Reverte for helping us plan and conduct the GTC observations successfully.
