SUPERNOVA 2002dk IN NGC 6616
     W. D. Li, University of California, reports the LOTOSS (cf.
IAUC 7906) discovery of an apparent supernova on unfiltered KAIT
CCD images on June 13.4 (mag about 18.0) and 14.2 UT (mag about
17.8).  SN 2002dk is located at R.A. = 18h17m43s.52, Decl. =
+22o14'53".4 (equinox 2000.0), which is 33".6 east and 35".3 north
of the nucleus of NGC 6616.  A KAIT image taken on June 7.4 showed
nothing at this position (limiting mag about 19.0).


SUPERNOVA 2002dj IN NGC 5018
     M. Riello, S. Benetti, G. Altavilla, A. Pastorello, and M.
Turatto, Osservatorio Astronomico di Padova; E. Cappellaro,
Osservatorio Astronomico di Capodimonte; and S. O'Toole, University
of Sydney, write:  "A spectrum (range 340-900 nm, resolution 1.0
nm) of SN 2002dj (cf. IAUC 7918), obtained on June 14.15 UT with
the Danish 1.54-m telescope (+ DFOSC) at La Silla, shows that it is
a type-Ia supernova well before maximum.  The spectrum shows the
strong P-Cyg profiles of Si II 635- and 596-nm over a relatively
blue continuum.  The spectrum closely resembles that of SN 2002bo
obtained 10 days before maximum light.  The expansion velocity
measured from the Si II absorption is 16700 km/s."


COMETS C/2000 C7, F2, F3, T5, T6, X9; C/2002 L5 (SOHO)
     Further to IAUC 7918, D. Hammer reports measurements of
additional comets found by R. Kracht (the 2000 comets listed below)
and T. Scarmato (C/2002 L5) on SOHO website C2 images.  Reduced
astrometry and orbital elements by B. G. Marsden appear on the
MPECs cited below.  C/2000 X9 belongs to the Meyer group (cf. IAUC
7832); the rest are Kreutz sungrazers.
