We confirm the pre-discovery detection of the possible nova on a 13x120s dithered stacked CCD image obtained with the Open University PIRATE Planewave CDK17 0.43m Dall-Kirkham f/6.7 telescope at the Observatorio Astronomico de Mallorca (Costitx, Spain), using an SBIG STX 16803 CCD Camera (with a Kodak 4k x 4k chip with 9 microns sq. pixels) and Baader clear filter. The object is detected with R=17.9+-0.3 mag at RA = 00:43:24.17, Dec = +41:19:23.5 (J2000, accuracy 0.4 arcsec). Nothing is detected at this position on a 13x120s dithered stacked CCD image obtained with the same instrument on 2012-02-16.784 UT, with an upper limit of about 18.5 mag. M.
