PSN J21534826+1003249   2015 08 20.24  *  21 53 48.26 +10 03 24.9  16.3 U   22E  18N  G22-55-26 D 0



2015 08 21.79215

This transient was observed on 2015 08 21.79215 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. 16.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 48.24; 24.8 (J2000.0, mean residuals of 0.1" on both axes).




2015 08 21.670

This possible supernova in MCG +2-55-26 was detected with 18 x 10 min images using a clear filter Photometry: Mag 16.44 +/- 0.22 C (V for ref; USNOA2) Astrometry: RA 21 53 48.38 Dec +10 03 25.4 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

2015 09 06.9111

Observation of this transient object was made on 2015 09 6.9111 by G. Locatelli at Maritime Alps Observatory (MPC K32) Cuneo, Italy, with a Schmidt-Cassegrain telescope 0.25 m. f/10 + Rc filter. Performed photometry returns a value of 16.025 +/- 0.53 Rc magnitude (reference R mags from NOMAD1). Link to image: https://www.flickr.com/photos/snimages/20579992263/
