Paolo Campaner report the discovery of a PSN in NGC5406 (mag. about +18.2) on two unfiltered CCD images taken on 2015 February 18.0542 UT at the Ponte di Piave Observatory - Italy in the course of the Italian Supernovae Search Project. Telescope: Reflector D=0.40m f/5.5 Exposure 55sec. No known variables stars or minor planets.




2015 02 19.06003

This transient was observed on 2015 02 19.06003 by G. Masi, remotely using the 17"-f/6.8 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. 18.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 21.29; 49.4 (J2000.0, mean residuals of 0.2" on both axes).




2015 02 18.079

This transient was observed on 015 02 18.07960 by M.Caimmi - C92 Valdicerro Observatory - Loreto (AN) Italy using 0.24-m f/6.5 SCT - CCD Atik 314L. Stack of 15 unfiltered b2x2 frames x 30 sec unguided exposures, show the source at 18.9 mag. End figures for astrometry were AR. 21.27s DEC. 50.0" position was measured from reference stars UCAC-4 catalogue. The image of this observation is available http://www.oav.name/public/PSN_J14002117+3854517_20150218,079.jpg




2015 02 19.0542

Confirm this transient observed on 2015 02 19.05423 by M.Caimmi - C92 Valdicerro Observatory - Loreto (AN) Italy using 0.24-m f/6.5 SCT - CCD Atik 314L. Stack of 15 unfiltered b2x2 frames x 30 sec unguided exposures, show the source at 18.7 mag. End figures for astrometry were AR. 21.28s DEC. 49.8" position was measured from reference stars UCAC-4 catalogue. The image of this observation is available http://www.oav.name/public/PSN_J14002117+3854517_20150219,0542.jpg




2015 02 18.079
