POSSIBLE NOVA IN NGC 205
     S. Nakano, Sumoto, Japan, reports the discovery of a possible
nova in NGC 205 by K. Itagaki (Teppo-cho, Yamagata, Japan) on seven
unfiltered CCD frames taken around Oct. 5.56 UT with a 0.60-m f/6.0
reflector.  Itagaki reports that the object brightened from mag
16.4 to 16.1 in about 1 hr, and he provided the following
approximate position:  R.A. = 0h40m15s.8, Decl. = +41o44'20"
(equinox 2000.0), which is about 3'35" from the center of NGC 205
(= M110) in p.a. 330 deg.  A confirming unfiltered CCD image was
obtained by R. Kushida with a 0.40-m reflector at Yatsugatake South
Base Observatory on Oct. 5.764, showing the new object at mag 15.8
and at precise-position end figures 15s.26, 19".8 (measured by Y.
Kushida), which is 77" west and 193" north of the center of NGC
205.  Nothing appears at this position to mag 18 on survey frames
taken by Itagaki on May 28 and July 30 and to mag 19 on Kushida's
image taken on Oct. 3.65.


COMETS C/2002 R4, R5, R6, R7, R8, S3, S4, S5 (SOHO)
     Further to IAUC 7975, D. Hammer reports his measurements for
several additional comets found on SOHO website images (C3
coronagraph, except where noted) by R. Kracht (C/2002 R4, C/2002
R8, C/2002 S5; via the C2 coronagraph only), R. Matson (C/2002 R5
and C/2002 S4, the latter also visible in C2), D. Evans (C/2002 R6),
J. Sachs (C/2002 R7), and X. Leprette and S. Hoenig (C/2002 S3).
The reduced astrometry and orbital elements by B. G. Marsden appear
on the MPECs cited below.  C/2002 R4 belongs to the Marsden group
(cf. IAUC 7832), and C/2002 R8, though weakly determined, evidently
belongs to the Meyer group; C/2002 R5 appears to be related to
C/1999 R1, a point first made by Kracht; C/2002 S4 and C/2002 S5
are members of the Kracht family (IAUC 7952).  The rest are Kreutz
sungrazers.
