A probable nova, designated PNV J09553757+6900146, was discovered in M81 on January 30, 2016 (Hornoch et al. ATEL #8632). No X-ray source is detected at this location in a 20.2 ks Chandra ACIS-I observation performed on February 1, 2016, implying a 3-sigma upper limit of 0.000215 counts/s (0.2-2 keV). Assuming a 3 keV APEC (Smith et al. ApJ 556, L91 2001) and Galactic absorption
of 4e20 cm^{-2} (Dickey & Lockman, 1990, ARAA, 28, 215), translates into a limit of the absorbed luminosity of 2.3e36 erg/s. Assuming a super-soft source blackbody spectrum with the same column translates into a limit of 1.0e38 erg/s.
