Supernova 2000cx in NGC 524

This page is devoted to information on Supernova 2000cx in NGC 524 Basic information on this SN, including the last reported brightness, on this Supernova can be found on the main page. Information on the original web pages for many of these images can be found on the Supernova links web page.

sn00cx_i.jpg Another discovery from the LOSS team. This one was discovered at magnitude 14.5 and rising, and it quickly became brightest SN, so far, for the year 2000. It sits beyond the visible edge of a Mag 11.3 equatorial galaxy called NGC 524 and is a pretty easy shot. This SN is now known to be of the over luminous type Ia know as the 1991T type. Maximum brightness happened at around July 26, 2000 when it got to mag 13.2. We have a DSS Photometry reference image made by Odd Trondal. Icon created from Nick Suntzeff YALO color image.
