I049742 from Potential Comet Confirmation Page at the Minor Planet Center. Each frame is a stack of 20x2 min images stacked on the motion vector of this new object. In the fifth frame it is clear of background stars and clearly shows a teardrop shaped coma and short tail about 17 arc sec long oriented at about PA 303. Images by D. T. Durig and P. S. Hearn at the Cordell-Lorenz Observatory, The University of the South, Sewanee, Tennessee, USA. OBS CODE 850.
Images may be used if photo-credit is given and you notify me of their use at ddurig@sewanee.edu
