P. Vreeswijk (University of Amsterdam) and S. Smartt (Institute of Astronomy, Cambridge) report that images taken by Gerry Gilmore and Rosie Wyse on the Isaac Newton Telescope, La Palma on Feb. 2.9 UT have allowed an accurate projection of the position of SN 2002ap on the pre-discovery images reported in IAUC 7816. Within the new errors, the SN is not coincident with the V = 21.2 object reported as a possible progenitor. The difference in position between SN 2002ap and this object is 1.7 +/- 0.3" where the error is dominated by the error in the position of the faint object. There is no object in the pre- discovery images at the SN position, to limiting magnitudes (5-sigma, 2" aperture radius) of U = 20.8, B = 22.1, V = 22.0, and I = 20.8.
