G. Viscome (Lake Placid, NY).  0.37-m f/6 reflector + telecompressor + CCD.
E. Helin, K. Lawrence, B. Arthur and J. Smallwood (Palomar).  0.46-m
   Schmidt.  Measurer Lawrence.  Object slightly diffuse.

     Total visual magnitude estimates: Oct. 9.39 UT, 11.3 (A. Hale, near
Chaparral, NM, 0.41-m reflector); 9.49, 11-12 (D. E. Machholz, Colfax, CA,
0.25-m reflector).

SATURN
     V. J. Tejfel and G. A. Kharitonova, Laboratory of Lunar and
Planetary Physics, Kazakhstan Academy of Sciences, Alma-Ata, report:
"During photographic observations with the 1-m telescope at the
high-altitude observing station at Assy in good atmospheric conditions
during Sept. 24-30 we independently detected a light spot (cf. IAUC 6079,)
6080) in Saturn's equatorial region extending some 30-35 deg in longitude.
The spot is most clearly visible on photographs in blue and violet and
has less contrast in green, orange and red.  Its longitude (uncertainty
+/- 2 deg) in both systems I and III changed noticeably: Sept. 25.712 UT,
LI = 224 deg, LIII = 56 deg; 28.733, 253 deg, 344 deg; 29.597, 265 deg,
327 deg.  From these observations the spot's own rotation period was
estimated tentatively as 10h22m."
