Supernova 2006X in Messier 100
I ran across an announcement yesterday that a supernova had been discovered in Messier 100 in the constellation Coma Bernices on Feb 7th, 2006 by Shouji Suzuki and M. Migliardi. This makes a total of 5 supernova that have been observed in M100. The supernova was at estimated magnitude 15.3 when discovered and is now at magnitude 14.4 according to Migliardi (I’d put it closer to magnitude 15.0 judging from nearby stars on my unstacked images — I’m not an expert however; I’m not sampling with a reference filter; and the Stellacam2 is more sensitive to IR).
Below is the result of stacking 120 images I took last evening just between midnight and 1 am. Equipment used was a Celestron Nexstar11, F3.3 focal reducer, and Stellacam2 video camera. Temperature was 14 degrees, no wind, no clouds, transparency excellent, and turbulence 7/10. Blue text in image shows magnitude for nearby stars from AAVSO chart. Background brightness from the nearly full moon made brightness/contrast adjustments a bit of a challenge.

The older I get, the worse a speller I become as well. Not sure why, deteroriating brain cells I suppose.
I can’t wait to get some dark skies to re-image this again. The NASA SWIFT sites released some images see
