2013 08 14.584

Discovered by Koichi Itagaki, Yamagata, Japan, using 0.18-m reflector + unfiltered CCD. This Nova was confirmed on the frames taken on August 14.750 UT using 0.60-m f/5.7 reflector + unfiltered CCD after discovery. Then CCD magnitude is 6.3. Also nothing is visible at this location on his past frames (limiting mag.= 13.0) taken on 2013 August 13.565 UT.

D. Denisenko, V. Lipunov, E. Gorbovskoy (SAI MSU), A. Parkhomenko, A. Tlatov, D. Dormidontov, V. Senik (Kislovodsk Solar Station of Pulkovo Observatory) report on behalf of the MASTER robotic telescopes network: we have obtained confirmation image of PNV J20233073+2046041 with MASTER-Kislovodsk telescope (double 0.40-m f/2.5 reflector + 4kx4k CCD) on 2013 Aug. 14.826 UT. The object appears saturated on 60-sec exposure. The magnitude (unfiltered with the red zero point) measured by robot is 7.7m. Comparison of MASTER-Kislovodsk images obtained on 2013 May 13.998 (with the variable at 17.1m, limit 18.9) and on Aug. 14.826 (m_lim=18.7) is posted at http://master.sai.msu.ru/static/OT/NovaDel2013-MASTER.jpg (6'x6' FOV). We also note that the Nova is identical to the blue star USNO-B1.0 1107-0509795 (R.A.=20h23m30s.713, Decl.=+20o46'03".97, B1=17.20, R1=17.45, B2=17.39, R2=17.74) and ultraviolet source GALEX J202330.7+204603 (NUV=17.88+/-0.04). Color-combined (BRIR) DSS finder chart is uploaded to http://master.sai.msu.ru/static/OT/J202330+204604-BRIR5x5.jpg (5'x5' FOV).

Visual magnitude estimate by Patrick Schmeer, Bischmisheim, Germany: 2013 Aug 14.829 UT 6.0. Sequence: V magnitudes, Instrument: 20x80 binoculars




2013 08 14.8942

This transient was observed by Gianluca Masi, Patrick Schmeer and Francesca Nocentini, remotely using the 17" robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. Unfiltered images show the source at mag. 6.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 30.68s; 03.7" (J2000.0, mean residuals of 0.2" on both axes)




2013 08 14.8432

We performed some follow-up of this object through a 0.43-m f/6.8 astrograph + CCD from MPC Code I89 (Nerpio, Spain) and through a 0.25-m f/6.3 Schmidt-Cassegrain + CCD from MPC code C82 (Sorrento, Italy). On our images taken on August 14.8, 2013 from MPC I89 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude 6.8 at coordinates: R.A. = 20 23 30.72, Decl.= +20 46 03.4 (equinox 2000.0; UCAC-3 catalogue reference stars). On our images taken on August 14.8, 2013 from MPC C82 we can confirm the presence of an optical counterpart with unfiltered CCD magnitude 6.9 and R-Filtered magnitude 6.1 at coordinates: R.A. = 20 23 30.68, Decl.= +20 46 03.7 (equinox 2000.0; CMC-14 catalogue reference stars).
