We report follow-up photometry in the Sloan g, r, and i bands, 240s per band, of the nova M31N 2017-10a ( = PNV J00423905+4123006) from observations on the night of 29 October 2017 with the Wide Field Camera of the Isaac Newton Telescope*.
The nova was discovered 2017/10/14.039 by Kamil Hornoch, H. Kucakova, and M. Wolf using the 0.65-m telescope at Ondrejov (ATEL # 10849). The spectroscopic confirmation by S. Fabrika et al. (ATEL # 10887) using the Russian BTA telescope shows that this M31 nova belongs to the Fe II class.
The following AB magnitudes, calibrated using the PanSTARRS-1 DR1 catalog, were obtained with the INT WFC:
r = 19.21 +/- 0.08, 2017 Oct. 29.850 UT
i = 18.67 +/- 0.13, 2017 Oct. 29.963 UT
g = 20.01 +/- 0.08, 2017 Oct. 30.059 UT
The astrometric calibration was done using the Gaia DR1 catalog. The nova position on the INT WFC images is R.A. = 00h42m39s.05, Decl. = +41o23'00".5 (equinox J2000.0) and agrees within 0.1 arcsec with the one reported by Kamil Hornoch (ATEL # 10849)
