2013 10 31.0951

This possible supernova was observed on 2013 10 31.095 using a 0.41-m reflector and ST9XE CCD. The unfiltered image showed the object at mag 17.6 (UCAC-3 R mag reference stars) and position end figures= 24s.53 and 32".0 Doug Rich, Hampden, Maine, U.S.A.



2013 10 30.1791

Details from discoverers: G. N. Gray (age 10) of Greenwood, NS, Canada and D. J. Lane of Stillwater Lake, NS, Canada report their discovery of an apparent supernova (mag about 18.0) on an unfiltered image taken with a 0.36-m f/5.5 Schmidt-Cassegrain telescope+CCD taken on 2013 Oct 30.1791 UT. Its presence was confirmed by the discoverers at 2013 Oct 31.001 UT and by Doug Rich, Hampden, ME, USA at 2013 Oct 31.095 UT. The apparent SN is located at R.A.= 18h3m24s.59, Decl = +70o13'30.6" (equinox 2000.0), which is about 3" east and 7" north of the nucleus of PGC 61330. Nothing is visible at this location on images taken many occasions in the past two years (all limiting mag fainter than 18). Nothing is present on Digitized Palomar Sky Survey images.



2013 10 31.720

This transient was observed on 2013 10 31.720 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 17.4 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 24.49s 31.3" (J2000.0, mean residualsoof 0.2" on both axes).



2013 10 31.9053

SN to be confirmed in PGC 61330 detected with 3 x 3 min images (exp 9 min). Astrometry: RA 18 03 24.12 Dec +70 13 26.4 (ref stars UCAC2) Photometry: 17.00CR +/-0.02 (USNO A2R Ref stars 163R, 170R, 172R, 173R). Measure on unfiltered image. Observer and measurer: Xavier Bros, ANYSLLUM OBSERVATORY, Ager, Spain. T-350mm f4.6. Link to image and further information: http://www.anysllum.com/PSN_PGC61330.jpg



2013 11 02.116

This possible supernova in PGC 61330 was detected with 3 x 15 min images using a clear filter Photometry: Mag 18.81 +/- 0.67 C (V for ref) Astrometry: RA 18 03 24.58 Dec +70 13 30.9 These data were collected remotely by Joseph Brimacombe, Cairns, Australia.

2013 11 05.9868

Revised astrometry/photometry on this possible supernova observed on 2013 11 05.9868 - 05.9888 averaging 5 images taken with a 0.41-m reflector and ST9XE CCD. The unfiltered images showed the object at mag 17.1 (USNO-B 1.0 R mag reference stars) and position end figures= 24s.52 and 31".5 Doug Rich, Hampden, Maine,U.S.A.
