  We present an analysis of Kitt Peak National Observatory and Lowell
Observatory observations of comet 103P/Hartley 2 obtained from August through
December 2010. The results are then compared with contemporaneous observations
made by the EPOXI spacecraft. Each ground-based dataset has previously been
investigated individually; the combined dataset has complementary coverage that
reduces the time between observing runs and allows us to determine additional
apparent periods at intermediate times. We compare CN coma morphology between
ground-based datasets, making nine new measurements of apparent periods. The
first five are consistent with the roughly linearly increasing apparent period
during the apparition found by previous authors. The final four suggest that
the change in apparent period slowed or stopped by late November. We also
measure an inner coma lightcurve in both CN and R-band ground-based images,
finding a single-peaked lightcurve which repeats in phase with the coma
morphology. The apparent period from the lightcurve had significantly larger
uncertainties than from the coma morphology, but varied over the apparition in
a similar manner. Our ground-based lightcurve aligns with the published EPOXI
lightcurve, indicating that the lightcurve represents changing activity rather
than viewing geometry of structures in the coma. The EPOXI lightcurve can best
be phased by a triple-peaked period near 54-55 hr that increases from October
to November. This phasing reveals that the spacing between maxima is not
constant, and that the overall lightcurve shape evolves from one triple-peaked
cycle to the next. These behaviors suggest that much of the scatter in apparent
periods derived from ground-based datasets acquired at similar epochs are
likely due to limited sampling of the data.
