Schwartz. SN 2003O is located at R.A. = 3h38m09s.13, Decl. = +40o58'38".0 (equinox 2000.0), which is about 9".8 west and 21".0 south of the center of UGC 2798. The new object is not visible on the red/blue Palomar Sky Survey digital images or on CCD frames taken by Rich on 2002 Sept. 1.20 and Oct. 15.28 (limiting mag 18.0).
The confirmation image was taken by Michael Schwartz with the 32 inch Tenagra II telescope located in southern Arizona.
- The discovery image was taken with a 10″ LX200 and ST9XE camera.
- The discovery image is “noisy” due to the presence of a full moon on the night it was taken.
