SUPERNOVA 1988Q IN ANONYMOUS GALAXY
     C. Pollas, Observatoire de la Cote d'Azur, reports his
discovery on a IIIa-J plate, exposed with the CERGA Schmidt, of a
possible supernova at R.A. = 16h31m30.05, Decl. = +34 54'34.4 (equinox
1950.0), which is 0".9 east and 4".6 south of the nucleus of an
anonymous galaxy.  On July 5.91 UT, the magnitude was ~ 18.


SUPERNOVA 1987A IN THE LARGE MAGELLANIC CLOUD
     D. Allen, Anglo-Australian Observatory; and J. Spyromilio, P.
Meikle, and G. Varani, Imperial College, London, write:  "We find a
dramatic increase in prominence of the [Ni I] line at 3.119 microns in
SN 1987A.  In a spectrum taken at the Anglo-Australian Telescope on
July 1, the line had about half the intensity of Brackett-alpha.  It
has been virtually constant since Feb., although the local continuum has
fallen fourfold in that time.  The line is quite narrow, with FWHM
(measured at resolution 400) of 3000 km/s.  The companion line at 3.951
microns may also be present in the wing of Brackett-alpha.  We encourage
observers with access to longer-wavelength transitions of this and
similar species to keep the supernova under close scrutiny."
