SUPERNOVA 2002cj IN ESO 582-G5
     M. Ganeshalingam and W. D. Li, University of California at
Berkeley, report the LOTOSS (cf. IAUC 7514) discovery of an
apparent supernova on unfiltered CCD images taken with the 0.8-m
Katzman Automatic Imaging Telescope (KAIT) on Apr. 21.5 (mag about
16.0) and 22.5 UT (mag about 15.9).  SN 2002cj is located at R.A. =
15h21m20s.71, Decl. = -19o51'27".3 (equinox 2000.0), which is 1".4
west and 3".9 south of the nucleus of ESO 582-G5.  KAIT images
taken on Apr. 9.5 (limiting mag about 16.0) and Mar. 28.5 (limiting
mag about 18.0) showed nothing at this position.


V4741 SAGITTARII = POSSIBLE NOVA IN SAGITTARIUS
     N. N. Samus, Institute of Astronomy, Moscow; O. Durlevich,
Sternberg Institute; and E. Kazarovets, Institute of Astronomy,
inform us that the designation V4741 Sgr has been given to this
object (cf. IAUC 7878, 7879).
     M. Fujii, Okayama, Japan, reports that low-dispersion spectra
(range 440-720 nm; resolution about 1 nm) of this object, obtained
on Apr. 18.80 UT with the Fujii Bisei Observatory 0.28-m telescope,
show a strong H-alpha emission line with a width of 2800 km/s
(FWHM).  Other emission lines include the Fe II series (37, 38, 42,
49, 55, 74), Na I (589 nm), and He I (706.5 nm), characteristic of
an Fe II-class nova.  Additional photometry provided by T. Kato,
Kyoto:  Apr. 4.769, [11.8 (A. Takao, Kita-kyushu, Japan,
unfiltered CCD); 12.794, [14.0 (K. Haseda, Aichi, Japan, T-Max 400
film; revision to IAUC 7879); 17.828, 9.6 (Takao); 17.769, V =
10.16 (K. Nakajima, Kumano, Mie, Japan, CCD); 17.788, R_c = 9.31
(Nakajima).


COMETS C/2002 G4, C/2002 G5, C/2002 H1 (SOHO)
     Further to IAUC 7875, D. Hammer has reported his measurements
of three additional Kreutz sungrazers.  C/2002 G4, C/2002 G5, and
C/2002 H1 were found by X. Leprette, R. Kracht, and K. Cernis,
respectively, on SOHO website C2 images.  C/2002 H1 was also
visible in the C3 coronagraph.  The reduced astrometry and orbital
elements by B. G. Marsden appear on the MPECs cited.
