We report the discovery of a new nova candidate in the M81 galaxy on 16x200s stacked R filter CCD images, obtained with the 80 cm Ritchey-Chretien F/9.6 Joan Oro telescope at Observatori Astronomic del Montsec, owned by the Catalan Government and operated by the Institut d'Estudis Espacials de Catalunya, Spain, using a Finger Lakes PL4240-1-BI CCD Camera (with a Class 1 Basic Broadband coated 2k x 2k chip with 13.5 microns sq. pixels).
The new object is clearly detected with a magnitude of R = 19.5±0.3 mag on 2016-06-20.91 UT. Its coordinates are RA = 9h54m53.95s, Dec = +69o02'33.8" (J2000, 1σ accuracy 0.2"). Nothing was found at this position in our preceding observation on 2016-06-07.91 UT, with an upper limit of about R = 20.5, and no object is present within a 4" radius in the VizieR/CDS data base. Astrometry and photometry were calibrated based on the SDSS DR7 photometry catalogue.
Spectroscopic follow-up observations are encouraged.
