Supernova in Large Magellanic Cloud=1987A
R.McNaught, Siding Spring Observatory, Australia has telephoned to
report the discovery of a supernova in the LMC found by Shelton and
Duhalde at Las Campanas Observatory in Chile and independently by
Albert Jones in New Zealand.
McNaught provides the following precise position:
RA 5h35m50s.12 DEC -69d17'58".0 (1950).
Shelton reports the object was of mag 4.5 on 1987 Feb 24.333UT.
McNaught also gives  the following observations made today(Feb 24):
10.56UT 4.8; 11.20, 4.8: 16.18, 4.5; 16.48, 4.5; 17.12, 4.4; 17.30,
4.5.
McNaught has found the object prediscovery on films taken with 85mm
FL lens: Feb 23.443, 6.0; 23.445, 6.2.
Nothing appeared different in the field on a photo of Feb 22.465UT
to mag 12.5.
G.Garradd also reports that no change in the field was detected on
a picture of Feb 22 to 14.5.
McNaught suggests that the object may be identical with a mag 12
star which is very blue. This is possibly a foreground galactic
star or possibly a Wolf Rayet Object.
