Zhijian Xu(Nanjing,Jiangsu,China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 18.0) on a 40-s survey image (limiting mag about 18.5) taken by Xing Gao in Xingming Observation Sky Survey(C42) around Aug.01.66671 UT.using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The new object approximately located at R.A.=14h 10m 50s.17 Decl.=+55°25'24".0(equinox 2000.0). Which is about 1.6" west and 14.9" south of the center of the host galaxy. Nothing is visible at this position on archival images taken on Jun.25(limiting mag 18.0),Jun.24(limiting mag 18.0) or on the DSS from Jun.08,1996(limiting mag about 19.7).

2013 08 01.972

This transient was observed on 2013 08 01.972 by Gianluca Masi and Francesca Nocentini, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show the source at mag. 18.4 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 50.00s; 24.2" (J2000.0, mean residuals of 0.2" on both axes).

2013 08 03.91003

This object was observed by Federica Luppi and Luca Buzzi from Schiaparelli Observatory, Varese, Italy. In a stack of images totalling 9 minutes of unfiltered exposure time, the object has position end figures 50s.00, 24".3 and magnitude 19.0.

2013 08 02.260

This possible supernova in PGC 2501716 was detected with 1 x 10 min images using a luminance filter Photometry: 18.11 +/- 0.10 L (V for ref) Astrometry: RA 14 10 50.05 Dec +55 25 24.6 These data were collected remotely by Joseph Brimacombe, Cairns, Australia.
