Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report a discovery of TCP (mag.= 11.7) in Aql on two 40-s unfiltered CCD frames taken around 2014 Feb. 21.8564 UT ( limiting magnitude=13.2 ), using a 105-mm f/4 camera lens (+SBIG STL6303E camera). We have confirmed immediately the appearance of our discovery this PN on five 3-s unfiltered CCD frames taken around 2014 Feb 21.8695 UT ( limiting magnitude=18.0 ), 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 two past survey frames taken on 2013 Dec 07.392 UT(limiting mag.= 13.1) and 2014 Feb. 15.866 UT (limiting mag.= 13.1) nor on USNO-B1.0, We have checked in Minor Planets. nearest star in USNO B1.0 has position end figures 15s952, 41"60, distance 6".8, magnitudes B2=16.52 R2=14.50 I=13.67

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) can't confirm an OT candidate - TCP J19001574+0132356. Object not visible on 3x15sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.4-m f/3 telescope + CCD (KAF09000) on Feb. 22.4897, 2014. No new objects in the FOV 35'x35', down to mag. limit ~16.0R.

I took conformation images of this transient object following to CBET TOCP report with 0.5m Astrograph+FLI ProLine PL11002M CCD camera in V, Rc, Ic (T11, iTelescope.NET) at Mayhill, NM, USA, remotely. But I also can not identify any new object. I compared my images with DSS images with Aladin at Simbad. (Seiichiro Kiyota, Kamagaya, Chiba, Japan)

We can't confirm this transient on images taken remotely from H06 (New Mexico, Mayhill). No new objects down to magnitude ~16 (FOV 49.0' x 32.7'). Moreover looks like comet C/2012 X1 (LINEAR) was located just at the position announced in the discovery report. Regards, Ernesto Guido, Nick Howes & Martino Nicolini
