The transient is well visible on 30s V-filtered images taken at Hankasalmi observatory, Finland with a 40 cm telescope. Position: R.A.: 20:54:22.60 Dec: +60:17:08.87 (J2000.0). Magnitude: V=11.90 +/ -0.01 (a single Tycho star as the reference star). Time series observations ongoing.

I took confirmation images of this transient object using 0.15-m f/7.3 refractor + SBIG STL-11000M (T16, iTelescope.NET) remotely at Nerpio, Spain. Photometry results were B=12.65, V=11.62, Rc=10.76, Ic=10.02 using TYC 4247-1185-1 as a comparison. Position end figures were 23.75 and 6.91 using UCAC3 as a reference catalog.

Light curve from 2014-03-08 22:00 UT to 2014-03-09 04:00 UTC shows the object first at near constant brightness of V=11.87 then rapidly brightening with rate of 0.1 mag/hr starting at 00:30 UTC. The last measurement at dawn 2014-03-09 03:52 UTC is V=11.55 +/- 0.02.

Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report a discovery of TCP object (mag.= 11.7) in Cep on two 40-s unfiltered CCD frames taken around 2014 Mar. 08.79175 UT ( limiting magnitude=13.7 ), using a 105-mm f/4 camera lens (+SBIG STL6303E camera). We have confirmed immediately the appearance of our discovery this TCP object on five 5-s unfiltered CCD frames taken around 2014 Mar. 08.7987 UT ( limiting magnitude=18.3 ), using a Meade 200R 0.40-m f/9.8 reflector (+SBIG STL1001E camera). (lens magnitude of referred catalogue Hipparcos, others reference catalogue GSC-ACT) Nothing is visible at this location on past survey frames taken on 2014 Mar. 03.8405 UT(limiting mag.= 13.9) but we find same object 12.9 mag 07.780571 UT (limiting mag.=13.8) nor on DSS, USNO-B1.0, We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 23s425, 16'47"12, distance 20"8,magnitudes B2=20.47 R2=19.12 I=18.10

E. Gorbovskoy, V. Lipunov, D. Denisenko (SAI MSU) on behalf of the larger MASTER team report the following upper limits and detection by MASTER-Amur VWF (very-wide field camera, d=72 mm, f/1.4 + 11 Mpix CCD): 2014 Mar. 05.846 UT, <14.3; 06.828, <13.9; 07.823, 13.3+/-0.4. Comparison of Mar. 05, 06 and 07 MASTER-Amur-VWF images is uploaded to http://master.sai.msu.ru/static/OT/NovaCep2014-MASTER-Amur-VWF.jpg
