- 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 1 sigma 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 T(c) [HJD] = 2455210.6502 +/- 0.0064, which is within 1.3 sigma of the time derived from a Spitzer observation of the same event.
