(216) KLEOPATRA
     F. Marchis, European Southern Observatory (ESO), La Silla, in
collaboration with D. Hestroffer, A. Cellino, P. Tanga, and V.
Zappala, reports on the direct-imaging observation of (216)
Kleopatra, and evidence of the bifurcated shape of this main-belt
asteroid:  "Observations were done on Oct. 25.27-25.31 UT with the
adaptive optics system ADONIS on the 3.6-m reflector at La Silla in
the K_s band (2.15 microns).  The observations, which were
performed under excellent seeing (0".5), seem to rule out wrong
(spin) pole solutions and show a double source with two distinct
lobes of similar size (flux ratio is about 0.8) and a separation
estimated to be 0".125.  Details can be found at
http://sc6.sc.eso.org/~fmarchis/Science/Kleopatra."


V1333 AQUILAE
     S. A. Ilovaisky and C. Chevalier, Observatoire de Haute-
Provence, write:  "Observations of V1333 Aql, which includes the
optical counterpart of the Aquila X-1 x-ray transient, obtained
with the 1.2-m Haute-Provence telescope on Nov. 3-9 UT, reveal that
the source apparently returned to its quiescent state sometime
between Nov. 8.8 and 9.8 UT.  The 6-month duration of this latest
outburst (turn-on was reported on May 8; cf. IAUC 7161) is one of
the longest observed since the 1990 and 1991 events (IAUC 5281 and
5507)."


NOVA IN THE SMALL MAGELLANIC CLOUD 1999 No. 4
     D. L. Welch, McMaster University, writes that the MACHO
collaboration (cf. IAUC 6312) has discovered an apparent nova in
the Small Magellanic Cloud.  Located at R.A. = 0h48m51s.7, Decl. =
-72o30'15" (equinox 2000.0), the nova peaked in brightness some
time between July 27 and Aug. 3 UT.  The last point before eruption
was taken on July 27.679, when the object was fainter than V = 19.5.
The next observation, on Aug. 3.667, indicates that the nova had
brightened by at least 6.5 mag and had saturated the CCD in both V
and R.  The most recent observation, on Nov. 17.471, shows the nova
to be at V = 17.0.

10.58, 10.9; 26.51, 11.3; Nov. 1.53, 11.5; 9.53, 12.2.
