PSN J14354590+2443179   2014 06 05.9800*  14 35 45.90 +24 43 17.9  17.0 U     2E 13S  UGC9396    6 - 



2014 06 05.9600

I confirm the presence of this PSN (mag.+16.8) from several unfiltered images taken by 0.35m. Sch.-Cass. F/5.5 + SXVR H-9 CCD camera; 90sec. exposure; limit mag.+19.0; Giancarlo Cortini (Monte Maggiore Observatory-Predappio-ITALY).




2014 06 05.98

Mirco Villi, Mario Bombardini, Alessandro Benazzi (Urania Lamonia Observatory-Faenza-Italy) report the discovery of a possible supernova in UGC 9396 with a 0,35 mt. Sch.-Cass. f/5.0 + Sbig ST9 CCD camera on several unfiltered images, 60 sec. exp., at mag. 17,0, limit mag. 19,0. The new object is located at RA14h35m45s, DECL +24°43’17” (J2000.0) which is 2” E and 13” S from the galaxy’s centre. Previous images of the galaxy taken on May 23, 2014 show nothing at that position, also in POSS II red and blue plates. No know minor planets are in that area during discovery time.




2014 06 05.9898

This transient was observed on 2014 06 05.9898 by G. Masi, remotely using the 17"-f/6.8 corrected Dall-Kirkham 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. 17.0 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 46.00; 18.3 (J2000.0, mean residuals of 0.2" on both axes).




2014 06 05.91157

Simone Leonini, Siena, Italy, report the pre-discovery by M. Conti, G. Guerrini, P. Rosi, L.M. Tinjaca Ramirez and himself of the PSN in UGC09396 (mag. about +16.28 +/-0.16 – USNO B1) on unfiltered CCD image (limiting mag. about +19.5) taken on 2014 Jun. 05.91157UT at the Montarrenti Observatory in the course of an automatic survey of the Italian Supernovae Search Project. Telescope: RC D=0.53m f/8.7. Detector: U47. Astrometry: R.A. 14h35m45.97s, Decl.+24°43’18.4”- 2000.0. Nothing is visible at the position of the apparent supernova on image taken on 2014 May. 17.97431 (limiting mag about +18.5).

2014 06 06.176

This possible supernova in UGC 9396 was detected with 3 x 10 min images using a clear filter Photometry: Mag 17.22 +/- 0.46 C (V for ref) Astrometry: RA 14 35 45.99 Dec +24 43 18.2 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.

2014 06 07.895

Several low resolution spectra of this transient were obtained on 2014 06 07.895 by G. Masi, remotely using the 14" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 15, 300-seconds images were taken using a 100 lines/mm grating, with a dispersion of 34.5 angstroms/pixel. They were co-added and the resulting image shows Si II absorption around 6350 angstroms, suggesting this is a type Ia supernova.




2014 06 09.301

Follow-up This possible supernova in UGC 9396 was detected with 9 x 10 min images using a clear filter Photometry: Mag 17.18 +/- 0.57 C (V for ref) Astrometry: RA 14 35 46.02 Dec +24 43 18.3 These data were collected remotely by Joseph Brimacombe, Coral Towers Observatory, Cairns, Australia.
