C. Y. Peng, University of Arizona; R. R. Treffers, M. Modjaz, and A. V. Filippenko, University of California at Berkeley; and M. W. Richmond, Rochester Institute of Technology, report that SN 1997dc (cf. IAUC 6715-6717) is visible in prediscovery CCD images obtained as part of the Lick Observatory Supernova Search (cf. IAUC 6627) on July 26 and Aug. 1 and 5 UT. It might be present on July 21, as well. The object was in all cases fainter than the threshold for automatic detection.
