Following the posting on the Central Bureau's Transient Object Confirmation Page about a possible transient (PNV J18562170-0852300) in Sct we performed some follow-up remotely through Gras network near Mayhill, NM using a 0.25-m, f/3.4 reflector + CCD. We can't confirm this transient. We searched an area with a radius of 15' around the reported discovery coordinates J2000 Position: 18 56 21.70 -08 52 30.0. Limiting magnitude: 15.0 (unfiltered). by Ernesto Guido, Giovanni Sostero and Nick Howes.

Nothing is visible at the above location on three frames (Fov 60.5' x 40.8' ) taken on around 2012 Apr. 13.34666UT (limit mag.= 17.0), remotely using the iTelescope T5 0.25-m f/3.4 astrograph + unfiltered CCD (SBIG ST-10XME) at near Mayhill, NM, U.S.A. (H06). Observer T. Yusa, Osaki, Japan. Link to my image; http://space.geocities.jp/yusastar77/supernova/PNinSct_120413.htm
