Rochester Scientist Discovers New Comet

Cerro Tololo

A University of Rochester scientist has discovered a new comet – the first to be discovered by an astronomer associated with the University of Rochester or the Rochester area in over a century, his colleagues believe. David Cameron, a visiting scientist in Eric Mamajek’s research group in the Department of Physics and Astronomy, recently discovered a new short-period comet named Comet P/2015 PD229 (ISON-Cameron). Cameron discovered the comet last August while analyzing images taken in May 2015 by Mamajek with the Dark Energy Camera (DECam) on the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory in Chile.
