PERIODIC COMET KOPFF (1994s)
     This comet has been recovered by C. W. Hergenrother, Lunar and
Planetary Laboratory, on CCD frames obtained by S. M. Larson with
the 1.5-m reflector at the Catalina Station.  The images are very
faint (near threshold on the second night).  The comet is stellar
in appearance, with no hint of a coma or tail.  The indicated
correction to the prediction on MPC 22032 is Delta(T) = +0.02 day.

SUPERNOVA 1994ae IN NGC 3370
     F. Patat, European Southern Observatory (ESO) and Padova
University, reports that preliminary reduction of his CCD
observations of SN 1994ae with the ESO/Dutch 0.9-m telescope at La
Silla yields the following magnitudes:  Dec. 1.36 UT, V = 13.12,
V-R = -0.01; 3.35, 13.13, -0.01; 4.35, 13.13, -0.02.  The constant
luminosity over three days and the V-R colors suggest that SN
1994ae is at maximum light.
     Visual magnitude estimates:  Dec. 1.00 UT, 13.5 (Z. Vician,
Hehalom, Hungary); 1.08, 13.6 (L. Szentasko, Veresegyhaz, Hungary).


SUPERNOVA 1994af IN ANONYMOUS GALAXY
     Patat also reports that a 10-min CCD exposure taken on Dec.
1.24 UT with the ESO/Dutch 0.92-m telescope shows this object (cf.
IAUC 6110) at magnitude R about 18.04; on Dec. 2.16, the supernova
appeared about 0.1 mag fainter.  SN 1994af was measured to be about
3" east and 1" south of the galaxy's nucleus; there are nearby
stars of mag R = 18.36 and 17.05 that are located 100" east, 30"
north, and 100" east, 90" south, of SN 1994af, respectively; a
bright star appears 72" east and 98" north of the supernova.
