Zhijian Xu(Nanjing,Jiangsu,China) and Xing Gao (Urumqi,Xinjiang,China), report the discovery of a possible supernova (mag approximately 16.3) on one 40-s survey image (limiting mag about 18.0) taken by Xing Gao in Xingming Observation Sky Survey(C42) around Oct.11.93917 UT. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ). The new object approximately located at R.A.=08h 11m 16s.45 Decl.=+25°10'47".4(equinox 2000.0). Which is about 6.0" east and 1.7" north of the center of the NGC 2536. Nothing is visible at this position on archival images taken on Mar.04(limiting mag 18.5),Mar.31(limiting mag 18.4), or on the DSS from Jan.10,1989(limiting mag about 19.9).

Follow-up of this object was observed with 5 x 60s images using an unfiltered Photometry: C2014 10 12.92994 08 11 16.47 +25 10 47.3 16.1 V. Follow-up image posted at URL http://njzhijian.lamost.org/Supernova/PSNJ08111645+2510474-1012.jpg. C42,Xingming Observatory,Mt. Nanshan. Observers Z.Xu,X.Gao,Measurers Z.Xu 0.36-m f/6.9 Schmidt-Cassegrain telescope and CCD.



2014 10 18.040

This transient was observed on 2014 10 18.04014 by G. Masi and P. Catalano, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 180-seconds exposures, unfiltered, show the source at mag. 16.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 16.46; 47.1 (J2000.0, mean residuals of 0.2" on both axes).
