Dear Dr. Kato,

    My CCD images show star at position alpha = 21h 03m 33s.7, 
delta = +29d 54' 9".4 which is 2" east and 18" north of the nucleus of
NGC 7013. CCD photometry: V = 15.23 +/- 0.05. This is not a new star.
Star is at Quick-V Northern Syrvey plate at same position.

                                                 sincerelly  D. Hanzl

RE:	possible supernova in ngc 7013


Steve,

While processing an image of ngc 7103 taken on Aug 1st at 1:36:45 AM loca=
l
California time, I believe I may have found a supernova.

Details of NGC 7013 in Cygnus:
RA =3D 21:03.6
DEC =3D +29:54
Mag 11.3
Size 4.8 x 1.4 arc min
I have a 20 minute exposure taken with a ST-8 and AO-7 adaptive =

optics on a Meade LX200 10" at F/6.3

Suspect supernova:

Mag: ~14
size: ??
located: Seperation =3D 18.82 Arc Secs,Position Angle =3D 186.70 =

degrees from the core. (Note: This is is only method Mr. Mulchin =

had to determine the suspect offset).

I have no way at the time to verify with a second image
(fogged in).

I have checked the POSS plates and find nothing there.
I also found an image or NGC 7013 from Enrico Prosperi taken =

08/31/97 with a HI-SIS22 camera and the supernova is not there.

How do I get confirmation on this? What is the next step?

Thanks
