[vsnet-alert 16975] Re: PNV J06000985+1426152: possible nova (13.5 mag) in Orion

TOCP update:
D. Denisenko, V. Lipunov and E. Gorbovskoy (SAI MSU) report on behalf of the larger MASTER team: MASTER-Tunka robotic telescope (0.40-m f/2.5 reflector + 4kx4k CCD) observed the position of PNV J06000985+1426152 in survey mode on 2014 Mar. 03.521-03.574 UT, two nights before the discovery by H. Nishimura. The object was not present on the sum of five 60-sec unfiltered exposures to the limiting magnitude 18.5. Following the posting at CBAT TOCP, we have pointed MASTER-Tunka again at this area of sky. On the first 60-sec unfiltered exposure on 2014 Mar. 05.656 UT we confirm the new bright object at the following position: 06 00 10.03 +14 26 12.2. The object is definitely an outburst of the star USNO-B1.0 1044-0081025 with the following coordinates and magnitudes in USNO-B catalogue: 06 00 10.048 +14 26 12.76 B1=19.35 R1=19.88 B2=20.02 R2=20.39 I=17.85. Based on the outburst amplitude it is likely a dwarf nova of SU UMa or WZ Sge type. Comparison of Mar. 03
 and 05 MASTER-Tunka images is posted at http://master.sai.msu.ru/static/OT/J060009+142615-MASTER-Tunka.jpg

R.A. 06h00m09.85s  Decl. +14°26'15.2"  (J2000.0)
13.5 mag (unfiltered CCD) on 2014 March 5.475 UT
"Discovered by H. Nishimura, Kakegawa, Japan, on four 10-s frames (limiting magnitude = 14.5) using 200-mm f/3.2 lens + Digital camera, who writes nothing is visible at this location on his past frames taken on 2014 Jan. 22, 26, Feb. 2 and 11 UT (limit mag.= 14.5) using same patrol camera."
