PNV J17292916+0054043

PNV J17292916+0054043   2014 05 22.778 *  17 29 29.16 +00 54 04.3  12.1 U             Oph       9 0

2014 05 22.778

Discovered by H. Nishimura, Shizuoka-ken, Japan, who confirmed this star on four frames taken May 22.778 UT using 200-mm f/3.2 lens + a Digital camera, also who writes nothing is visible at this location on a frame taken on May 21.578 UT using same patrol camera.

Photometry: B= 12.3, V= 12.7, Rc= 13.0, position end figures 29s.47, 04".3, remotely using a T17 0.43-m f/6.8 astrograph + CCD at the iTelescopeNET, SSO, Australia. Observer T. Yusa, Osaki, Japan. Image was posterd at URL http://space.geocities.jp/yusastar77/supernova/PNinOph_1400523.htm

I took conformation images of this PSN with 0.70m Astrograph (F/6.6) + FLI PL-09000 CCD camera at Siding Spring Observatory site of iTelescope.NET, remotely. Photometric results are V=12.37, R_c=12.38, I_c=12.35. This color might be indicate that this PSN are dwarf nova or other peculiar variables. Position end figures are 29.49 and 04.30.

Mag.= 12.8, position end figures 29s.50, 04".3 (refer to UCAC4 catalog) observed by T. Noguchi, Chiba-ken, Japan, on a 10-s frame (limit mag.= 15.5) with 0.23-m f/6.3 Schmidt-Cassegrain + unfiltered CCD. See an image posted at http://park8.wakwak.com/~ngc/images/PNVinOph_20140523.jpg.

F.Castellani, R.Belligoli, C.Marangoni, from Monte Baldo Observatory (Ferrara di Monte Baldo,Verona,Italy), report photometric results of this PNV by nine images taken remotely with Planewave 20" (0.51m) CDK (f/4.4) + FLI PL-09000 CCD camera at Siding Spring Observatory site of iTelescope.NET on 20140523.697: VJ=12.509 (err=0.002); RJ=12.343 (err=0.002); IJ=12.173 (err=0.007). These photometric measurements might be indicate that this PNV should be a dwarf nova or other peculiar variables.

Mag. B= 12.41, V= 12.43, Rc= 12.29, Ic= 12.14 observed by K. Yoshimoto, Yamaguchi, Japan, from a four stacked 60-s B frame and four stacked 30-s V, Rc, Ic frame using 0.16-m f/6.3 reflector + CCD + Johnson-Cousins filter, who writes star shows blue color. Magnitude refer to Landolt catalog. An V-filtered image posted at http://orange.zero.jp/k-yoshimoto/PNV-J17292916+0054043.jpg

S.Moretti, A.Maitan, S. Tomaselli and V. Tinella have taken a low res. spectra (24.4 A/px)of this PSN with 0.42m Newton telescope (F/5.2) + Moravian G2 1600 CCD camera equipped with 100 line/mm grism at Bastia Obs. (ARAR - Bastia Ravenna - Italy - MPC 197). No bright emission line in visible and the coninuum is blue

2014 05 23.6

K. Ayani, Bisei Astronomical Observatory (BAO), Ibara, Okayama, Japan, obtained a low-resolution spectrogram (range 400-800 nm; resolution 0.5 nm at H-alpha) of this possible nova on May 23.6 UT with the BAO 1-m telescope. The spectrum shows narrow emission lines of H-alpha, H-beta, and He II 468.6, superposed on a blue continuum. The spectrum resembles that of a dwarf nova. Our spectrum is posted at http://www.bao.city.ibara.okayama.jp/astro/2014/pnv/PNV_J17292916+0054043_May23.png.
