The magnitude equation was recalculated for the bright (8.0 to 10.5 photographic magnitude) stars from Fatchikhin's catalogue. It was found to be: Δmx = -0arcsec.0088±0arcsec.0016, Δmy = +0arcsec.0115±0arcsec.0024 (mean errors). With this value of the magnitude equation corrections of Newcomb's constant of precession were computed for the 768 stars common with the AGK3 catalogue. These are equal to (for 100 years): Δk = -0arcsec.17±0arcsec.10, Δn = +0arcsec.29±0arcsec.20 (probable errors).
