SUPERNOVAE 2004be AND 2004bf
     Further to IAUC 8312, K. Shimasaki, M. Moore, and W. Li report
the LOSS discovery of two apparent supernovae on unfiltered KAIT
images:

SN       2004 UT       R.A.  (2000.0)  Decl.   Mag.     Offset
2004be   Apr. 6.28   10 00 19.47  -24 48 13.8  17.0  4".0 W, 2".4 N
2004bf   Apr. 7.44   13 49 15.45  +35 15 12.5  17.5  17".1 E, 14".8 S

Additional KAIT magnitudes:  SN 2004be in ESO 499-G34, Mar. 28.25
UT, [18.0; Apr. 8.22, 16.7.  SN 2004bf in UGC 8739, Mar. 6.45,
[18.5; 23.48, [18.0; Apr. 8.43, 17.5.


SUPERNOVA 2004bg IN UGC 6363
     Further to IAUC 8316, M. Armstrong reports his discovery of an
apparent supernova (mag about 15.5) on unfiltered CCD images taken
on Apr. 7.965 and 8.936 UT.  SN 2004bg is located at R.A. =
11h21m01s.53, Decl. = +21o20'23".4 (equinox 2000.0), which is
approximately 14".2 east and 7".4 north of the center of UGC 6363.
Nothing was visible at this position on Armstrong's image taken on
2003 Mar. 7 or on Palomar Sky survey red and blue plates.  M.
Mobberley, Cockfield, U.K., confirmed the new object on an
unfiltered CCD image taken on Apr. 8.828 with a 0.35-m reflector.


SUPERNOVA 2004bd IN NGC 3786
     T. Hamane, K. Kinugasa, and H. Kawakita, Gunma Astronomical
Observatory (GAO); and H. Yamaoka, Kyushu University, report that a
low-resolution spectrum (range 460-660 nm) of SN 2004bd (cf. IAUC
8316), obtained with the GAO 0.65-m telescope (+ GCS) on Apr. 8.5
UT, shows it to be a type-Ia supernova near maximum.  The expansion
velocity, determined from the Si II 635-nm absorption minimum, is
about 9600 km/s.


COMET C/2001 Q4 (NEAT)
     Visual total-magnitude estimates:  Mar. 17.40 UT, 6.3 (D. A.
J. Seargent, Cowra, N.S.W., 2x25 binoculars); 21.37, 6.3 (S. T.
Rae, Tamahere, New Zealand, 8x21 binoculars); 25.00, 6.0 (J.
Shanklin, Stanley, Falkland Islands, naked eye); 28.01, 5.6 (S. F.
Hoenig, La Silla, Chile, naked eye); Apr. 1.76, 5.6 (Seargent, The
Entrance, N.S.W., naked eye).
