SUPERNOVA 2009jr IN IC 1320
On 2009 October 8 we received an e-mail from Ron Arbour of South 
Wonston, England reporting his detection of a possible supernova in the 
galaxy IC 1320 during searches for the UK Nova/Supernova Patrol. The 
object, of approximately magnitude 15.5-16.0, was recorded on a number 
of unfiltered images (limiting magnitude 18.8) around 2009 Oct 8.8312UT 
using a 0.4-m f/5 Newtonian reflector and Starlight Xpress CCD.

It is located at:
RA 20h 26m 26.03s DEC +02 54' 32.1" (2000)
Offsets from galaxy:   5.1" E   3.4" S

The object was not visible on the Digitised Sky Survey POSS II Blue 
plate (1990-07-19) or the POSS II Red plate (1990-08-19) or listed on 
CBAT's Minor Planet Checker.

In a further message Ron reports that he has obtained a confirmatory 
image on Oct 10.747UT. David Briggs, Havant, England has also obtained 
an image with a 0.60-m f/4.7 Newtonian reflector on Oct 8.925UT showing 
the possible supernova.

The object was designated Supernova 2009jr on CBET 1964 issued today 
(October 11). Congratulations to Ron on the discovery of his 21st 
supernova.
