COMET TAKAMIZAWA-LEVY (1994f)
Kesao Takamizawa and David H. Levy report their discoveries of
what appears to be the same comet, as follows:
1994 UT R.A. (2000) Decl. m1 Observer
Apr. 14.756 21 24.0 + 4 48 12.5 Takamizawa
15.4 21 23.0 + 5 45 10.5 Levy
K. Takamizawa (Saku-cho, Minami-Saku-gun, Nagano-ken, Japan). Two
4-min photographic films, 0.10-m f/4.0 camera. Comet is diffuse
with central condensation and coma diameter about 1'.
Communicated by S. Nakano.
D. H. Levy (Tucson, AZ). Visual observation with 0.41-m reflector.
Comet diffuse with slight condensation and a broad, faint,
fanshaped tail. Motion toward northwest at about 0.3 deg/day.
SUPERNOVA 1994J IN ANONYMOUS GALAXY
B. Schmidt and R. Kirshner, Harvard-Smithsonian Center for
Astrophysics (CfA), report that a spectrum (320-900 nm) taken by J.
Huchra (CfA) with the Multiple Mirror Telescope (+ Blue Channel) on
Apr. 12 UT shows this object to be of type Ia, about 3 months past
maximum light. The redshift of the host galaxy, derived from Ca
H+K absorption and H-alpha emission, is cz about 0.06, in fair
agreement with that reported by Filippenko et al. (IAUC 5971).
GRO J0422+32
C. Chevalier and S. A. Ilovaisky, Observatoire de Haute-
Provence, write: "CCD photometry of the optical counterpart of
this x-ray transient has been obtained with the 1.2-m OHP telescope
in the quiescent state during two runs: Feb. 1-9 and Mar. 3-10,
mostly in the Ic and Rc bands. Variance analysis of this new set
shows power at a period of 5.09 hr (consistent with the value
previously derived from our 1993 data; see IAUC 5692) and also at
one-half, one-third, and even one-fourth of this value. Folding
the data reveals a complex and variable light curve which is far
from being of an ellipsoidal type. The maximum full amplitude is
0.2 mag, but it varies from night to night. The mean V magnitude
for both runs was 20.66 and 20.56, respectively, with V-Ic = +1.83
in February."
