SN 2006X was a Type Ia supernova about 60 million light-years away[citation needed] in Messier 100, a spiral galaxy in the constellation Coma Berenices. The supernovae was independently discovered in early February 2006 by Shoji Suzuki of Japan and Marco Migliardi of Italy.
SN 2006X is particularly significant because is is a Type Ia supernova. These supernovae are used for measuring distances, so observation of these supernovae in nearby galaxies are needed for calibration. Fortunately, SN 2006X is located in a well-studied galaxy, and it was discovered two weeks before its peak brightness, so it may be extraordinarily useful for understanding supernovae and for calibrating supernovae for distance measurements. It may even be possible to identify the progenitor of the supernovae.
