Supernovae

The links at the left take you  to web pages that  document the brightness of various supernovae that  I  was able to capture data for. The graphs depict the brightness of the supernova over time as well as how it's intensity in visible light compares to that  of our sun if the two were at the same distance from us.   

The measurements were taken in the visible light without any color filters except a Baader UHC-s filter using an Orion SSP V2 on a SN8 at 5 minute exposure dark subtracted and flat applied .

If you  are interested in how to convert ADU ( Analog Digital Units) values to  a Magnitude value, check out this link http://www.warren-wilson.edu/~physics/Contemp-Astronomy/starmag/starmag.html. You  will need the ADU and Magnitude numbers for a reference star  in the same field as the primary object as well as the ADU value of the object in question.  I use Nebulosity to get the ADU figures.

A listing of Supernovae brighter than 17 Mag. can be found at this site
