S. Leonini, G. Guerrini, P. Rosi, L.M. Tinjaca Ramirez and M. Conti (Siena, Italy) report follow-up photometry of iPTF13ebh on a stack of Rs filter 15 x 10sec. images taken on 2013 November 16.776 UT at Montarrenti Observatory (part of Italian Supernovae Search Project). Mag. Rs = 17.08 +/-0.13 (USNO-B1) Astrometry: RA 02 22 00.10 +/- 0.16; DECL. +33 16 13.2 +/- 0.13. Telescope/Detector: RC 0.53m f/8.7 + U47.

2013 11 26.869

This transient was observed on 2013 11 26.869 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 15.2 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 59.99s; 13.8" (J2000.0, mean residuals of 0.2" on both axes).

2013 11 26.9066

This object was observed by Federica Luppi and Luca Buzzi from Schiaparelli Observatory, Varese, Italy. In a stack of images totalling 3 minutes of unfiltered exposure time, the object has position end figures 59s.98, 13".1 and magnitude 15.1.
