PSN J12532935+0209390


Supernova in the NGC4772  Galaxy 






I'd like to thanks Chuck Kimball for providing the initial data and above image on the SN.

image 2012cu (= PSN J12532935+0209390) (= SNhunt136), CBET 3146 discovered 2012/06/14.559 by Koichi Itagaki
Found in NGC 4772 at R.A. = 12h53m29s.35, Decl. = +0209'39".0
Located 3" east and 27" south of the center of NGC 4772 (Discovery image) (SNhunt image) (L. Elenin and I. Molotov image) (Joseph Brimacombe image) (Rafael Benavides image) (Stan Howerton image) (William Wiethoff image)
Mag 15.6:6/18, Type Ia (References: CBAT TOCP, SN 1988E)

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

     I will be  monitoring and calculate its magnitude (dimness) over time. As you  can see by the graph below, from the time I started to monitor it on Aug. 30 2011  it had increased in brightness. Please note that  the smaller the magnitude number the brighter the object is.

     I will keep this graph updated by getting at least one image a night (weather permitting) till it is no longer visible.

     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.

These measurements were taken in the visible light without any color filters using an Orion SSP V2 on a SN8 at 5 minute exposure dark subtracted and flat applied.


These images will be updated as I get more data.
