Zhangwei Jin(Ningbo, Zhejiang, China) and Xing Gao (Urumqi, Xinjiang, China), report the discovery of a possible supernova (mag approximately 16.4) on a 40-s survey image (limiting mag about 19.5)taken by Xing Gao in Xingming ObservationSky Survey(C42) around Mar .24.91344 UT,2013. using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=350-mm @f/6.9 ).the new object approximately located at R.A. =18h 25m 01s.98 Decl.=+27°31'53".7(equinox 2000.0). Which is about 12.6" west and 13.3" south of the center of the NGC6632. Nothing is visible at this position at this position on archival images taken on Mar.20,2013. (limiting mag 19.2) or on the DSS(POSS2/UKSTU Red) from May. 03,1989(limiting mag about 19.8) NET UCAC-3 XM44ZJ C2013 03 24.91344 18 25 01.98 +27 31 53.7 16.4 V C42

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J18250198+2731537 in NGC 6632. Object visible on 3x300sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.45-m f/2.8 telescope + CCD (KAF09000) on Mar. 25.462, 2013. Object located at 18h 25m 02s.00 +/- 0".11, +27d 31' 54".0 +/- 0".1 (UCAC-4) with magnitude 15.7U (mag. limit ~19.7m). Nothing is visible at this position on the POSS and POSSII images.

This possible supernova in NGC 6632 was detected with 3 x 15 min images using an infrared filter Astrometry: RA 18 25 01.98 Dec +27 31 54.0 Photometry: 15.56 +/- 0.05 IR > 700 nm (R for ref) These data were collected remotely by Joseph Brimacombe, Cairns, Australia.

The transient was observed remotely by Gianluca Masi with the 17" unit part of the Virtual Telescope robotic facility in Italy. Several unfiltered, 300-seconds exposures shows it, at mag 16.0 unfiltered (R-mag for the references stars from USNO B1.0 were used).
