PSN J18285823+2254106   2015 05 12.042 *  18 28 58.23 +22 54 10.6  16.3 U    9W   5S  N6641     2 1



2015 05 12.042

PSN detected by Fabio Briganti (ISSP) in the course of the CROSS Program in two different images taken with the Majoni telescope (SC 0,28 m) of the Col Drusciè Observatory. The PSN was confirmed by other two images taken: one on May 12.938 by Alessandro Dimai with the same telescope (SC 0,28 m) and one by Massimo Caimmi on May 12.889 with a SC 0,24m

correction offset: 8" East and 3" Sud.




2015 05 14.93034

This transient was observed on 2015 05 14.93034 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. 16.7 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 58.24; 08.4 (J2000.0, mean residuals of 0.1" on both axes).




2015 05 13.738

This possible supernova in NGC 6641 was detected with 4 x 10 min images using a clear filter Photometry: Mag 17.51 +/- 0.28 C (R/B for ref; 2MASS) Astrometry: RA 18 28 58.29 Dec +22 54 08.1 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

2015 05 12.88944

M.Caimmi from C92 - Valdicerro Observatory, Loreto - Italy (ISSP) confirm the PSN on image obtained on 2015 05 12.88944 with a 0.24m Schmidt-Cassegrain + Atik 314L CCD camera. The object position measured A.R.=18h28m58s.16 Decl.=+22°54'08".2 astrometry with respect to UCAC-4.
