PERIODIC COMET WEST-KOHOUTEK-IKEMURA (1987x)
J. V. Scotti, Lunar and Planetary Laboratory, reports his
recovery of this comet with the 0.91-m SPACEWATCH telescope at Kitt
Peak. There was a tail 69" long extending toward p.a. 291 deg. The
correction to the prediction on MPC 10520 is delta T = -0.11 day.

SUPERNOVA 1987A IN THE LARGE MAGELLANIC CLOUD
J. B. Hearnshaw and V. J. McIntyre, University of Canterbury,
Christchurch, report: "From Mount John Observatory spectra we have
observed two weak emission features at 367 and 375 nm in the
previously dark near-ultraviolet region. These features were absent
on and before July 30.471 UT, were first seen on Aug 7.490 UT and
have been slowly increasing during September."
NOVA IN THE LARGE MAGELLANIC CLOUD
R. H. McNaught, Siding Spring Observatory, reports that his
comparison of U.K. Schmidt V plates on Aug. 15 by M. Hartley and
on Sept. 11 by A. Savage shows no image at the nova's position to
mag 19.
Visual magnitude estimates by McNaught: Sept. 25.42, 13.7;
25.79, 13.7; 26.41, 13.7; 26.52, 13.7; 27.45 13.7; 27.77, 13.7.
CL 2244-02
G. Soucail, Y. Mellier, B. Fort and G. Mathez, Toulouse
Observatory; and S d'Odorico, European Southern Observatory, report:
"A spectrogram of the giant luminous arc in CL 2244-02 (z = 0.33)
was obtained after a run on the Canada-France-Hawaii telescope
during Aug. 19-23. A circular slit was punched on a special aperture
plate, and the signal was integrated over 10 hr in good weather
conditions. From 440 to 720 nm the spectrum shows a very
flat and non-stellar continuum without any easily identifiable
features. This reinforces the hypothesis of gravitational lensing,
probably of a QSO, by the core of this galaxy cluster (Soucail et
al. 1987, A. Ap. Lett. in press)."
