We report on narrowband CN imaging of Comet 103P/Hartley 2 obtained at Lowell Observatory on 39 nights from 2010 July until 2011 January . We observed two features , one generally to the north and the other generally to the south . The CN morphology varied during the apparition : no morphology was seen in July ; in August and September the northern feature dominated and appeared as a mostly face-on spiral ; in October , November , and December the northern and southern features were roughly equal in brightness and looked like more side-on corkscrews ; in January the southern feature was dominant but the morphology was indistinct due to very low signal . The morphology changed smoothly during each night and similar morphology was seen from night to night . However , the morphology did not exactly repeat each rotation cycle , suggesting that there is a small non-principal axis rotation . Based on the repetition of the morphology , we find evidence that the fundamental rotation period was increasing : 16.7 hr from August 13–17 , 17.2 hr from September 10–13 , 18.2 hr from October 12–19 , and 18.7 hr from October 31–November 7 . We conducted Monte Carlo jet modeling to constrain the pole orientation and locations of the active regions based on the observed morphology . Our preliminary , self-consistent pole solution has an obliquity of 10 ^ { \circ } relative to the comet ’ s orbital plane ( i.e. , it is centered near RA = 257 ^ { \circ } and Dec= + 67 ^ { \circ } with an uncertainty around this position of about 15 ^ { \circ } ) and has two mid-latitude sources , one in each hemisphere .
