SUPERNOVA 2000ej IN IC 1371
M. Schwartz, Cottage Grove, OR; and W. D. Li and A. V.
Filippenko, University of California at Berkeley, report the
discovery of an apparent supernova (mag about 18) on unfiltered
images taken with the 0.5-m Tenagra III telescope on Nov. 2.2 and
6.2 UT in the course of the LOTOSS (cf. IAUC 7514). The new object
is located at R.A. = 21h20m15s.66, Decl. = -4 52'40".5 (equinox
2000.0), which is 5".8 south of the nucleus of IC 1371. Photometry
of the supernova is difficult because of its proximity to the
bright nucleus of the host galaxy. An unfiltered image taken with
the 0.8-m Katzman Automatic Imaging Telescope on Sept. 29.2 showed
nothing at the position of SN 2000ej (limiting mag about 19.0).
SUPERNOVA 2000dw IN UGC 11955
Filippenko and Li also report that inspection of noisy CCD
spectra (range 330-1000 nm) of SN 2000dw (cf. IAUC 7511), obtained
on Nov. 1 UT with the Shane 3-m reflector at Lick Observatory,
reveals that the object is a normal type-II supernova. H-alpha has
a classic P-Cyg profile.
SUNGRAZING COMETS
Further to IAUC 7514 and 7485, D. Hammer reports his
measurements for eight additional Kreutz sungrazing comets found on
SOHO website images. Comet C/1997 T7 was found by X. Leprette; the
other seven objects were found by M. Oates. All eight comets were
seen in the C2 coronagraph, but only only C/1999 V2 was also
visible with the C3 instrument. The reduced observations and
orbital elements by B. G. Marsden are given on the MPECs cited
below.
