Discoverd by K. Itagaki, Yamagata, Japan, on an unfiltered CCD frame using 0.50-m f/6.8 reflector at Takanezawa station, Tochigi-ken. PSN was confirmed on the following five frames taken after the discovery. Nothing is visible at this location on his past frames and verifying was done on a frame (limiting mag.= 19.5) taken on 2008 April 5.596 UT. Discovery image is put at http://www.k-itagaki.jp/images/4303.jpg.

I took confirmation images of this PSN with 0.5m (f/6.8) Astrograph + FLI PL-11002M CCD at Mayhill, NM, USA of iTelescope.NET, remotely. Photometric results were B=14.36, V=13.65, Rc=13.42 and Ic=13.15. My image is available at http://meineko.sakura.ne.jp/ccd/PSN_J12215757+0428185.jpg Seiichiro Kiyota (Kamagaya, Japan)

We performed some follow-up of this object through a 0.10-m f/5.0 astrograph + CCD from MPC Code H06 (iTelescope, New Mexico). On our images taken on October 30.5, 2014 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude 13.2 and at coordinates: R.A. = 12 21 57.61, Decl.= +04 28 17.8(equinox 2000.0; UCAC-3 catalogue reference stars).

This transient was observed on 2014 10 31.15352 by G. Masi and P. Catalano, 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. 13.0 (R mags for the reference stars from UCAC-4; the PSN is affected by the galaxy's light). We also performed astrometry, getting the following end figures: 57.58; 18.6 (J2000.0, mean residuals of 0.2" on both axes).

This transient was observed on 2014 11 01.19274 by M.Caimmi - C92 Valdicerro Observatory - Loreto (AN) Italy using 0.24-m f/6.5 SCT - CCD Atik 314L. Stack of 19 unfiltered frames of 30 sec exposure (b2x2), show the source at 13.9 mag (presence of dense fog at times, during exposure) End figures for astrometry were AR. 57.58s DEC. 18.4" position was measured from reference stars UCAC-4 catalogue. The image of this observation is available http://www.oav.name/public/PSN_J12215757+0428185_20141101,1927.jpg
