SUPERNOVAE 2003ds AND 2003dt
     Further to IAUC 8117, J. Graham, W. Li, M. Schwartz, and P. R.
Holvorcem report two apparent supernovae found via LOTOSS on
unfiltered KAIT (SN 2003ds) and Tenagra II (SN 2003dt) images:

SN      2003 UT      R.A.  (2000.0)  Decl.    Mag.      Offset
2003ds  Apr. 14.3   10 18 58.35  +46 27 15.5  18.0   4".2 E, 1".2 N
2003dt  Apr. 22.5   20 47 17.56  + 0 18 42.8  17.5   23" W, 32" S

Additional approximate magnitudes (via KAIT unless otherwise noted):
SN 2003ds in NGC 3191, Mar. 25.3 UT, [19.5; Apr. 19.3, 18.5.  SN
2003dt in NGC 6962, 2002 Nov. 24.1, [18.8; Apr. 21.5, 17.5 (poor
discovery image via Tenagra IV).  Schwartz adds that SN 2002ha is
at mag about 19.6 on Apr. 22.5, located about 15" from SN 2003dt.


SUPERNOVAE 2002km-2002ky
     Further to IAUC 8119, M. Doi reports the following additional
i' magnitudes (all obtained after subtraction from the reference
images; uncertainty 0.1-0.2 mag), all for 2002 Dec. 8:  SN 2003km,
23.9; SN 2003kn, 27.3; SN 2003ko, 24.7; SN 2003kp, 25.5; SN 2003kq,
26.4; SN 2003kr, 25.3; SN 2003ks, 26.5; SN 2003kt, 25.1; SN 2003ku,
25.3; SN 2003kv, 26.4; SN 2003kw, 25.4; SN 2003kx, 25.0; SN 2003ky,
25.0.


COMET C/2003 G3 (SOHO)
     Further to IAUC 8111, D. Hammer reports measurements for a
comet found on C2 and C3 SOHO website images by J. Sachs.  Hammer
provides the following magnitudes (from C3 images and a clear
filter unless noted as C2, which included an orange filter):  Apr.
4.113 UT, 7.7; 4.196, 7.6; 4.279, 7.8; 4.363, 7.4; 4.446, 6.9;
4.529, 5.7; 4.564, 4.8 (C2); 4.613, 5.3; 4.621, 4.5 (C2); 4.679,
5.6; 4.685, 4.2 (C2); 4.768, 4.1 (C2); 4.838, 4.6 (C2).  The
reduced astrometry and parabolic orbital elements (q = 0.017 AU,
Peri. = 175 deg, Node = 88 deg, i = 170 deg) appear on MPEC
2003-G63.
