PERIODIC COMET HARRINGTON (1994g) This comet has been recovered by J. Scotti with the Spacewatch tele-

scope at Kitt Peak in strong moonlight, the comet images being diffuse and showing a 10′′ coma. The following positions indicate a correction of ΔT = −0.02 day to the prediction on MPC 18258 (ephemeris on MPC 23251):

SUPERNOVA 1994M IN NGC 4493 P. Wild, Astronomical Institute, University of Berne, reports his dis-

covery at Zimmerwald on Apr. 29.9 UT (confirmed on May 2.9) of a supernova (V ∼ 16) located at α = 12^{h}28^{m}35^{s}.1, δ = +0^{o}52′54′′ (equinox 1950.0), which is 3′′ east and 28′′ south of the nucleus of NGC 4493.
