SUPERNOVA 1996W IN NGC 4027
     W. D. Li, Y. L. Qiu, Q. Y. Qiao, J. Ma, and J. Y. Hu, Beijing
Astronomical Observatory (BAO), report the discovery of a supernova
found on CCD images taken on Apr. 10 and 11 with the 0.60-m
reflector during the BAO supernova survey.  SN 1996W (V about 16)
is located 3" west and 40" north of the center of NGC 4027 (R.A. =
11h59m30s.1, Decl. = -19o16'05", equinox 2000.0).  The object is
not present on an image taken on Mar. 1.
     L. Wang, and J. C. Wheeler, University of Texas at Austin and
McDonald Observatory, report:  "SN 1996W was observed on Apr. 12 UT
at the McDonald Observatory 2.1-m telescope (+ Imaging Grism
Instrument).  Inspections of a fully-reduced spectrum (range 424.7-
813.5 nm, resolution 2.0 nm) show that this is a type-II supernova
prior to optical maximum.  Weak but conspicuous H-alpha and H-beta
P-Cyg profiles are superimposed on a very blue continuum.  The
redshift of the host galaxy is about 1300 km/s as derived from
narrow emission lines of the neighboring H II region.  The
expansion velocity of the supernova ejecta is about 14 300 km/s, as
derived from the H-alpha P-Cyg profile.  The He I/Na I 587.6-nm
feature is also present."


SUPERNOVA 1996V IN NGC 3644
     P. Sicoli reports the following precise position of SN 1996V
obtained at Sormano by V. Giuliani and P. Ghezzi with the 0.5-m
reflector (+ CCD) on Apr. 11.939 UT:  R.A. = 11h21m31s.23, Decl. =
+2o48'40".4 (equinox 2000.0).
