Title: A coordinated campaign to observe Comet 2P/Encke around perigee

Abstract: We propose to characterize the nucleus and the activity of comet 2P/Encke. Encke will have a close approach to Earth during its perihelion passage in fall of 2013. This is the only opportunity for a close perigee passage observable from the ground until 2026. Furthermore the observing geometry of the comet between the last close perigee passage in 2003 and 2013 changed significantly, and we will be able to observe the cometary nucleus from a different vantage point. We will be able to compare the two apparitions, deduce the direction of the rotational angular momentum vector, locations of the active area(s), and determine the evolution of the spin state. This proposal is part of a multi-wavelength (visible and IR) and multi-methodology (lightcurves and coma morphology) approach to reach the goals described above. In this proposal we will concentrate on the coma morphology deduced from narrowband comet filters.
