Simone Leonini, Siena, Italy, report the discovery by S. Leonini, G. Guerrini, M. Conti, P. Rosi and L.M. Tinjaca Ramirez of an apparent supernova in NGC5837(mag. about +16.56CR +/-0.16 – USNO B1 catalogue) on two unfiltered CCD images (limiting mag. about +19.0) taken on 2014 March 09.99272 UT at the Montarrenti Observatory (IAU code C88)in the course of an automatic survey of the Italian Supernovae Search Project. Telescope/camera: RC 0.53m f/8.7 + U47. Astrometry: R.A. 15h04m40.09s +/-0.23”, Decl.+12degrees37arcmin54.0arcsec. +/-0.20”. No stellar source is visible at the position in our past images including one dated 2014 Mar 03 (limiting mag. about +17.0) and one dated 2014 Feb 24 (limiting mag. about +18.7). No known minor planets are marked in that position for the time of our observation.

2014 03 13.008

This transient was observed on 2014 03 13.008 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 corrected Dall-Kirkham robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 16.7 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 40.08; 54.0 (J2000.0, mean residuals of 0.2" on both axes).

This object was observed by Federica Luppi and Luca Buzzi from Schiaparelli Observatory, Varese, Italy. In a stack of images totalling 8 minutes of unfiltered exposure time, the object has position end figures 40s.08, 54".2 and magnitude 17.7.

2014 03 17.368

This possible supernova in NGC 5837 was detected with 9 x 10 min images using a red filter Photometry: Mag 17.06 +/- 0.17 R (R for ref) Astrometry: RA 15 04 40.11 Dec +12 37 53.7 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.
