Bin Wang(Shaoxing, Zhejiang, China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 16.7) on a 40-s survey image (limiting mag about 19.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Sep.02.89655 UT. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ). The new object approximately located at R.A. =08h 58m 52s.52 Decl.=+41°35'00".1(equinox 2000.0). Which is about 25.9" east and 11.7" north of the center of the PGC 25224. Nothing is visible at this position on archival images taken on Oct. 21(limiting mag 19.0 )or on the DSS from Dec. 08,1989(limiting mag about 19.8).

2013 11 01.989

This transient was observed on 2013 11 01.989 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. 16.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 52.48s; 34':59.9"" (J2000.0, mean residuals of 0.2" on both axes).

This possible supernova in UGC 4700 was detected with 5 x 5 min images using a clear filter Photometry: Mag 17.72 +/- 0.49 C (V for ref) Astrometry: RA 08 58 52.50 Dec +41 35 00.2 These data were collected by Joseph Brimacombe, Coral Towers Observatory,Cairns, Australia.
