Supernova 2002bo in NGC 3190

This page is devoted to information on Supernova 2002bo in NGC 3190 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 updates and links web pages.

sn02bo_i.jpg Discovered independantly by Paulo Cacella (Brasilia) and Yoji Hirose (Japan). A nice type Ia found in Leo, near the Virgo cluster, and easy shot. This appears to be a reddened sub-luminous type Ia supernova, found early. NGC 3189 is the southwestern side of NGC 3190. Bot NGC numbers are part of the same galaxy. NGC 3190 is the favored designation. We have a DSS Photometry reference image made by Odd Trondal.  Icon generated from the Pollux Observatory image.

sn02cv_i.jpg A group of Italian astronomers at Campo Imperatore Observatory were observing 2002bo when they discovered 2002cv, on the other side of the same galaxy. Two supernova in the same galaxy at the same time is a rare event! 2002cv is very unusual as it is only visible in IR. This is most likely due to it being behind a dust lane.
