SUPERNOVA IN NGC 3389
     Prof. G. de Vaucouleurs, University of Texas, sends the
following photoelectric observations made by himself and J. E. Solheim
with two-channel pulse counting photometer on 36-inch reflector of
McDonald Observatory.  Field aperture 32"; background corrections
applied.  Main comparison star (A) 260" East of NGC 3389 used as
local standard.  Several comparison stars in the range 12 < B < 16.5
were also measured to assist reduction of photographic observations.
Colors corrected by -0.1 mag. for red-shift and galactic absorption
are consistent with Arp's data for Type II SN 1959 in NGC 7331
(Ap. J., 133, 883, 1961) about 2 weeks past maximum.
