PERIODIC COMET BROOKS 2 (1994j)
S. Nakano, Sumoto, Japan, reports the recovery of this comet
independently by A. Nakamura and T. Seki, the following
observations showing a correction of Delta(T) = -0.01 day to the
prediction on MPC 18259:

SUPERNOVA 1994P IN UGC 6983
Penny Sackett, Institute for Advanced Studies, Princeton
University, reports her discovery of an apparent supernova on
spectrograms of UGC 6983 taken by A. Gould (Ohio State University)
with the 1.8-m telescope at Lowell Observatory on Apr. 20. The
long-slit spectrum was centered on H-alpha, with the long slit
aligned with the major axis of the galaxy. In addition to the
spectrum of the galaxy, there appears a spatially unresolved
feature with very strong, broad emission around H-alpha,
asymmetric and having width of about 3000 km/s; this unresolved
feature is much brighter than the H-alpha emission of the galaxy.
SN 1994P appears about 120" northeast of the galaxy's center
(toward p.a. 75o).
A. Filippenko, University of California at Berkeley, writes:
"P. Sackett faxed me an uncalibrated spectrum of her supernova
candidate in UGC 6983. The object does indeed seem to be a type-II
supernova, several months past maximum brightness. H-alpha is
purely (or nearly purely) in emission." M. W. Richmond, Princeton
University, measured the following position for SN 1994P from a V-
band image taken by T. Matheson (University of California,
Berkeley) with the Nickel 1-m reflector at Lick Observatory on
May 14 UT:
R.A. = 11h56m46s.57 +/- 0s.04, Decl. = +52o59'40".7 +/- 0".1
(equinox 1950.0); the corresponding offset from the galaxy
'nucleus' (defined as the bright patch in the central bar of the
galaxy, very slightly east of the geometric center) is 105".2 east
and 31".1 north. Richmond also measured V about 18.2 for the
supernova.
COMET SHOEMAKER (1994k)
Carolyn S. Shoemaker reports her discovery of another comet on
Palomar 0.46-m Schmidt films. The following positions are
available:
1994 UT R.A. (2000) Decl. m1 Observer
May 14.41284 17 21 58.03 - 9 43 26.5 17.3 Shoemaker

20.68248 17 18 40.22 -10 10 38.6 "
E. M. Shoemaker, C. S. Shoemaker, D. H. Levy, and T. B. Spahr
(Palomar). Films scanned and measured by C. S. Shoemaker.
T. Kojima (YGCO Chiyoda Observatory). 0.25-m f/6 reflector + CCD.
Comet is diffuse with strong condensation. Communicated by S.
Nakano.
