Scientific paper

We will discuss some results based on our imaging and photometric observations of Comet 103P/Hartley 2. Photometry was obtained during the 1991, 1997, and 2010 apparitions. These data reveal a strong secular decrease in production rates from 1991 to 2010 and a strong pre-/post-perihelion asymmetry in 2010. Imaging was obtained over 39 nights from 2010 July through 2011 January and analyses of the data are ongoing. We will discuss the CN coma morphology and make intercomparisons between gas species (CN, OH, C2, and C3), investigate the appearance and behavior of a possible dust jet, and refine the pole solution by combining the published results of multiple authors.
