R. Belligoli reports the discovery by Raffaele Belligoli and Flavio Castellani, members of ISSP's collaboration (Italian Supernovae Search Project) of a PSN on the images from Monte Baldo Observatory (Ferrara di Monte Baldo,Verona, Italy), with the 0.4m f.8 Ritchey-Chrétien telescope, in two images taken with a Kodak KAF 1001E CCD unfiltered, obtained on 2013 August. 31.939837 and 31.940278 UT. NGC 2748 coord. RA 09 13 38.88 DEC +76 28 10.8 - MAG 16.0.apparent but not in older images ( on 9th February 2013 as reference and the last image on 27th July 2013).

I confirm the presence of this PSN (mag.+ 15.9) from several unfiltered images taken by 0.35m. Sch.-Cass. F/5.5 + SXVR H-9 CCD camera; 90 sec. exposure; limit mag.+ 19.0; the offset is : 18 arcsec.E; 20 arcsec. S; Giancarlo Cortini (Monte Maggiore Observatory-Predappio-ITALY)

Belligoli e Castellani follow-up photometric measurements of the transient on Bj and Vj from Monte Baldo Observatory (Ferrara di Monte Baldo,Verona,Italy), with the 0.4m f.8 Ritchey-Chrétien telescope, in five images for each filter (Bj-Vj) taken with a Kodak KAF 1001E CCD, according 34 APASS reference stars. PSN J09133888+7628108 risults this night on 20130902.842 mag. 16.409 Bj (Err.0.034), 15.543 Vj (Err. 0.018) and 0.859 BV (Err. 0.034).

Asiago spectroscopic classification: this is a type Ic supernova around maximum light (http://sngroup.oapd.inaf.it)



2013 09 04.14623

This object was observed by Federica Luppi and Luca Buzzi from Schiaparelli Observatory, Varese, Italy. In a stack of images totalling 7 minutes of unfiltered exposure time, the object has position end figures 38s.86, 10".4 and magnitude 15.2.
