PSN J07370423+6535509   2014 11 02.0555*  07 37 04.23 +65 35 50.9  18.2 U   80E  18S  N2403      1 2


2014 11 02.0555

Paolo Campaner report the discovery of an apparent transient (unfiltered magnitude = 18.2) on images (limiting magnitude 19.0) obtained on November 02.0555 UT with a 0.4m telescope + CCD Atik 428ex at Ponte di Piave - Italy, in the course of the Italian Supernovae Search Project. The new object is located at A.R. = 07h37m50s.90, Decl. = +65°35'50".9 at 80" East and 18" South of the centre of Galaxy NGC2403.



2014 11 13.8215

Paolo Campaner report the confirmation (unfiltered magnitude = 18.5) on images (limiting magnitude 19.0) obtained on November 13.8215 UT with a 0.4m telescope + CCD Atik 428ex at Ponte di Piave - Italy, in the course of the Italian Supernovae Search Project. The new object is probably a LVB and not a PSN, considering the near distance of Galaxy NGC2403.

Paolo Campaner report a new brightness increase of LBV in NGC2403 (=SNHunt255) (=V22) at unfiltered magnitude +18.4 on several images (limiting magnitude +19.0) obtained on December 11.0771 UT with a 0.4m telescope + CCD Atik 428ex at Ponte di Piave - Italy, in the course of the Italian Supernovae Search Project.

2015 12 14.85685

This transient was observed on 2015 12 14.85685 by Andrea Mantero from C77 - Bernezzo Observatory using 0.25-m f/4 reflector - CCD Atik 314L Scale 1,33"/pixel. Stack of 12 unfiltered b1x1 frames x 240 sec guiding exposures, show the source at 18.7 Mag.(limiting magnitude 19.5) end figures for astrometry were AR. 07,37 04.25 s DEC. +65,35 46.8" position measured from reference stars UCAC-4 catalogue. https://www.flickr.com/photos/andreagalaxy/23136461624/in/dateposted-public/
