PERIODIC COMET WISEMAN-SKIFF (1993u) Suspected weak images of this comet on CCD frames obtained by B. Schmidt with the Multiple-Mirror Telescope at Mt. Hopkins on Feb. 2 (measured by G. V. Williams and Schmidt) are confirmed with an independent recovery by J. V. Scotti in Spacewatch images obtained by T. Gehrels at Kitt Peak on Dec. 16 (low altitude, twilight, rather poor seeing), after which Scotti found the comet on a single frame obtained on Dec. 10. 1993 UT R.A.
