We present the results of optical observations of C/NEAT (2001 T4), taken on 3 dates between October 2001 and September 2002, at the University of Hawaii 2.2 meter telescope. Coma was present for each observation, but the activity level was variable. We present surface brightness profiles, dust production rates and evidence for structure in the coma. There is a radial gradient in coma color, with the outer coma exhibiting the least red colors. The object's V-R and R-I colors indicate that this is one of the reddest objects with a Centaur-type orbit.
