SUPERNOVA 1989L IN NGC 7339
     K. C. Sahu and D. Carter, Observatorio del Roque de los
Muchachos, communicate:  "The 2.5-m Isaac Newton Telescope was used to
obtain spectra of SN 1989L.  Intermediate dispersion spectra (R = 1000)
with a coverage of about 100 nm around the H-beta line were obtained
on June 4.2 and 6.15 UT, and a low resolution spectrum (R = 1000) in
the range 350-750 nm was obtained on June 5.15.  The spectra show
strong P-Cyg profiles of the Balmer lines and suggest that the
supernova is of type II.  The outflow velocity, corresponding to the
difference between the rest wavelength in the galaxy's frame and
the minimum of the absorption dip, is about 5000 km/s."


3C 345
     M. T. Carini and H. R. Miller, Georgia State University; and A.
C. Sadun, Agnes Scott College, write:  "We have observed 3C 345 in
an exceptionally faint state.  The observations were made with the
Lowell Observatory 1.07-m telescope (+ nitrogen-cooled CCD camera).
The magnitude and colors observed on May 18 are:  V = 17.49, B-V
= +0.24, V-R = +0.26, R-I = +0.43.  Additional observations of this
object are encouraged."


PERIODIC COMET DU TOIT-NEUJMIN-DELPORTE (1989l)
     T. Seki, Geisei, Japan, reports his independent recovery

12.6 (C. S. Morris, Lockwood Valley, CA, 0.51-m reflector; 1'.5
tail toward east); 5.16, 12.3 (J. E. Bortle, Stormville, NY,
0.50-m reflector); 9.90, 13.3 (A. Boattini, Piazzano, Italy,
0.40-m reflector).
