image 2014J (= PSN J09554214+6940260), CBET 3792 discovered 2014/01/21.810 by Steve J. Fossey
Found in M82 at R.A. = 09h55m42s.14, Decl. = +6940'26".0 (= NGC 3034)
Located 54" west and 21" south of the center of M82 (Discovery image) (K. Itagaki image prediscovery) (LASSST image prediscovery) (Seiichiro Kiyota image) (Ernesto Guido, Nick Howes & Martino Nicolini image (Animation)) (L. Elenin and I. Molotov image) (T. Yusa image) (T. Noguchi image) (MASTER image) (Andrea Mantero image) (Joseph Brimacombe image) (Earl Foster image) (LOSS image) (Joseph Brimacombe image) (Constantine Emmanouilidi image) (Marco Verstraaten image) (Martin Mobberley image)
Mag 10.9:1/22, Type Ia-HV (References: ATEL 5786, ATEL 5789, ATEL 5791, ATEL 5793, vsnet-alert 16810, 16812, 16813, 16814, 16819, AAVSO Alert Notice 495, CBAT TOCP; SN 2008iz, 2004am)


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

         I will keep this graph updated by getting at least one image a night (weather permitting) till it is no longer visible.
 Note: The smaller the magnitude number the brighter the object.

     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  SBIG STF8300C on a SN8 at 5 minute exposure dark subtracted and flat applied.


These images will be updated as I get more data.
