DRACONID METEORS 1985
     S. Nakano, Tokyo, communicates the following observations of
Draconids on Oct. 8 in Japan.  Y. Yabu (Omi-Hachiman, Shiga-Ken)
gave hourly rates of 200 at 9h40m UT, 100 at 10h00m and 10 at
11h00m.  K. Watanabe and K. Nose (Sapporo Science Center) observed
83 meteors (mainly of mag 4-5) between 10h40m and 11h40m, deduced
a ZHR of 200 and remarked that maximum occurred before 10h00m.  Y.
Takeuchi (Tochigi-Ken) observed 39 meteors in 14 min around 10h00m.


SUPERNOVA 1985O IN ANONYMOUS GALAXY
     A. V. Filippenko, University of California at Berkeley, reports
that spectrograms obtained on Oct. 8 with the Lick 3-m telescope
(range 320-720 nm, resolution 1 nm) show supernova 1985O
(IAUC 4108) to be a type II object.  The H-alpha emission line is very
strong and broad, as is often the case in type II supernovae more
than a few weeks past maximum brightness.


U GEMINORUM
     This dwarf nova is undergoing a bright outburst, as indicated
by the following visual magnitude estimates, provided by J. A.
Mattei, AAVSO: Oct. 5.49 UT, 11.2 (L. Cook, Concord, CA); 5.52,
10.8 (Cook); 6.35, 8.8 (J. Griese, Stamford, CT); 7.31, 8.8 (C.
Scovil, Stamford, CT); 7.4, 9.3 (G. Dyck, N. Dartmouth, MA).
