SUPERNOVAE 2001ge, 2001gf, 2001gg, 2001gh, 2001gi, 2001gj
     G. Altavilla, S. Benetti, E. Cappellaro, A. Pastorello, M.
Riello, M. Turatto and L. Zampieri, Osservatorio di Padova; A.
Clocchiatti and C. Contreras, Universidad Catolica de Chile; I. J.
Danziger and P. Mazzali, Osservatorio di Trieste; and F. Patat,
European Southern Observatory (ESO), report the discovery of six
new supernovae on CCD frames taken on Nov. 11 (and confirmed on Nov.
18) during a search performed with the ESO/MPI 2.2-m telescope (+
Wide Field Imager).  The supernovae were identified by comparing
Nov. images with reference images taken (using the same equipment)
on previous observing runs, and none were visible on images taken
prior to last June (limiting mag 23.5-24.5).  The V magnitudes in
the table below are listed for Nov. 11 (V_1) and Nov. 18 (V_2).

SN 2001gf is located 2".07 west and 0".45 north of the center of
its host galaxy; the other supernovae are within 1" of their host
galaxy's nucleus.  Spectra obtained on Nov. 21 with the ESO 8.2-m
MELIPAL Very Large Telescope (+ FORS1) reveal the types and
redshifts listed above; from the spectral features, it is estimated
that SNe 2001ge and 2001gf were a few days before maximum and SN
2001gi was two weeks after maximum.  The spectrum of SN 2001gh
shows a very blue, almost featureless continuum, consistent with a
type-II supernova at very early phases.

     J. Watanabe, National Astronomical Observatory (NAO) of Japan,
reports the following antitail lengths and position angles for this
comet from I-band CCD images taken with the NAO 0.50-m f/12
reflector (noting the earth's passage through the orbital plane of
the comet on Nov. 20.18 UT):  Nov. 16.503, > 8'.5, 283 deg; 17.542,
> 6'.5, 300 deg; 18.526, > 7'.9, 302 deg; 19.555, > 6'.2, 317 deg;
22.372, > 4'.7, 1 deg.  Small scale jet-like structure near the
nucleus was also recognized on these images.
