Sorry : PSN J13004114+2759518 , K.Itagaki




2015 05 13.5196

This is a different PSN from PSN J13004114+2759518 (noted above line) which was discovered on 2013 May 5.




2015 05 13.5196

PSN was discovered on an unfiltered CCD frame taken with 0.60-m f/6.7 reflector, which is close located to Galaxy center. See the discovery image (http://www.k-itagaki.jp/images/5-psn.jpg). Nothing is visible at this location on his past frames including a recent frame (limiting mag.= 19.0) taken on 2015 Apr. 21.632 UT.




2015 05 13.92858

Confirmed object at 16.7R at 13 00 32.32 +27 58 41.0 (UCAC-4). Not on DSS. Nick James, ST9XE+C11. Image: http://www.nickdjames.com/supernovae/2015/PSNJ13003230+2758411_20150513_2217_ndj.jpg




2015 05 10.7559

This transient was found on pre-discovery image by Xingming Observation Sky Survey(C42) around 2015 05 10.75598 UT, using an unfiltered CCD ( + Celestron C14 Schmidt-Cassegrain telescope D=356-mm @f/6.9 ), mag. 17.6 V, getting the following end figures: 32.34; 41.3 (J2000.0). Observers Zhijian Xu, Xing Gao. Link to image: http://njzhijian.lamost.org/Supernova/PSN%20J13003230+2758411-C42-0510.jpg




2015 05 14.1257

I took confirmation images of this PSN with 0.43-m f/4.5 CDK astrograph + FLI-PL6303E CCD camera at iTelescope.NET, Mayhill, NM USA remotely. Photometric results were B=16.81, V=16.97 and Ic=17.00. Position end figures are 32.34 and 41.12 in RA and Dec. My image: http://meineko.sakura.ne.jp/ccd/PSN_J13003230+2758411.jpg Seiichiro Kiyota (Kamagaya, Japan)




2015 05 14.92095

This transient was observed on 2015 05 14.92095 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. 120-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: 32.32; 41.2 (J2000.0, mean residuals of 0.1" on both axes).
