Note: The red rays are from MARS which is just out of frame to the upper right.

A possible supernova of magnitude about R = 13 was discovered by J. Skvarc on four 60 s CCD images taken with a 0.60-m f/3.3 Cichocki telescope from the Crni Vrh Observatory. The object  is 60" W and 115" S from the center of M95.

The (J2000) coordinates reported for the object are
R.A. = 10h43m53s.72, Decl. = +11d40'17".7

     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.
