| b-v = Unknown SN 2010lt is a supernova located in the galaxy UGC 3378 in Camelopardalis. It was discovered by amateur astronomers Kathryn Aurora Gray, her father Paul Gray, of Fredericton, New Brunswick, Canada and David J. Lane of Stillwater Lake, Nova Scotia, Canada. Upon discovery, Kathryn Aurora Gray became the youngest person to ever discover a supernova, being 10 years old when she did so. The previous record was held by the 14-year-old Caroline Moore.

Discovery

The images were taken at Lane's Abbey Ridge Observatory on 31 December 2010 with a Celestron C14 0.36-meter f/5.5 telescope, and the supernova was spotted by them on 2 January 2011.

Discoverers

David J. Lane: SN 2010lt is Lane's fourth discovery of a supernova. The previous were SN 1995F, SN 2005B and SN 2005ea. All were discovered with Paul Gray.
Paul Gray: SN 2010lt is his seventh discovery of a supernova.
Kathryn Aurora Gray: her first discovery.

Description

SN 2010lt is about 20" west and 10" north of the galaxy center. It is a sub-luminous (1991bg-like) type Ia supernova and was discovered when near maximum light. The supernova could not be detected (detection limit approximately 18.5 of apparent magnitude) at its current position on images taken between October 2005 and March 2006.
