We report the discovery of faint probable nova located at RA(2000) = 00h41m26.23s, Dec(2000) = +41d43'50", which is 880.4" west and 1661.4" north of the center of M31. The object is visible on the all images, obtained on November 7th, 8th and 9th with the 50/70cm Schmidt telescope at NAO Rozhen, Bulgaria. The available R-magnitudes are:

2013 11 07.780 UT, R = 20.3+/-0.2 (5x300sec co-added)
2013 11 08.805 UT, R = 20.5+/-0.2 (5x300sec co-added)
2013 11 09.815 UT, R = 20.3+/-0.2 (5x300sec co-added)

Furthermore, we report additional R-band photometry for the novae candidates - Nova M31 2013-10d = PNV J00442132+4055220 (ATel # 5475, ATel # 5543), Nova M31 2013-10g = PNV J00432496+4121219 (ATel # 5502, ATel # 5522, ATel # 5543), Nova M31 2013-10h = TCP J00430483+4116306 (ATel # 5528, ATel # 5554) and Nova M31 2013-11a = iPTF13dya (ATel # 5539). The observations are carried out in eight nights at three different observatories:

50/70 cm Schmidt telescope + CCD FLI 16803, NAO Rozhen
35 cm Newton telescope + CCD SBIG 11000M, SAO Plana (ATel # 5558)
70 cm Cassegrain telescope + CCD FLI 16803, ZAH-Landessernwarte, Heidelberg
