Here is my shot of the Supernova in M100 Sc Spiral Galaxy or NGC4321 in the constellation of Coma Berenices.
It was captured with a 12" Takahashi Mewlon & ST8XE CCD in Nearly Full Moonlight......... so it was a difficult and noisy image to clean up.
This LRGB image is a 51 minute exposure.

M100 is a Mag 10.2 Sc type Spiral Galaxy in Coma Berenices.......it is approximately 7.5' x 6.4 arc minutes in size. Its diameter is estimated to be about 110,000 Light years across. Its distance is approximately 40 Million Light years away.
There are two other galaxies visible in the field of view which are NGC4322 - bottom and NGC4328 - right.
The Supernova 2006X's magnitude is on the rise at 11.5 Mag(?) from its original 17th mag at discovery on 02/04/06, according to IAU circular, but discovers website shows 02/07/06 at 15.3 mag.
Just added this info........
M100 has produced other Supernovae during the past century....SN 1901B, SN 1914A, SN 1959E, SN 1979C,..but SN 2006X has may surpassed the brightness of even 1979C, 11.6 mag.
SN 2006x is still rising and bound to be the brightest Supernova for the year..as well as could be the brightest ever recorded in M100.
To see the Supernova visually you'll need at least a 6" diameter scope and a dark moonless night.
Go check it out!!!
