2013 09 14.921

This transient was observed on 2013 09 14.921 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show a source at mag. 18.4 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 35.15s 30.2" (J2000.0, mean residuals of 0.15" on both axes).

2013 09 24.5336

This object was observed by P. Miller, P. Roche, A. Tripp, R. Miles, R. Holmes, S. Foglia, L. Buzzi, T. Vorobjov and T. Lister with the 2.0-m f/10 Faulkes Telescope North at Haleakala, HI. A single, R-Bessell filtered, 120-seconds image shows the PSN with position end figures 35s.14, 30".2, and R-mag 17.7.
