115331 Shrylmiles           Discovered 2003 Sept. 29 by D. Healy at Junk Bond Observatory.
Shryl Miles, of Benson, Arizona, has for years devoted herself to keeping the night skies free of light pollution. In 2005 these efforts were rewarded by the unanimous passage of a city-wide light pollution code that will benefit not only Benson, but all residents of and visitors to Cochise County.
