			AAVSO ALERT NOTICE 148 (September 3,1991)

NOVA SCUTI 1991

The Central Bureau for Astronomical Telegrams and Frank Bateson, Director of the 
Variable Star Section of the Royal Astronomical Society of New Zealand, inform 
us that RASNZ member Paul Camilleri, Cobram, Victoria, Australia, has 
photographically discovered a nova in Scutum on August 30.468 UT at photographic 
magnitude 10.3, visual magnitude 10.5. R. H. McNaught, Anglo-Australian Observatory, 
reports the precise position (1950.0) of the nova as measured on an Uppsala Southern 
Schmidt plate taken August 31.54 to be:

			RA = 18h 44m 26.58s 	Dec. = -08deg 24' 12.0"

Paul reports that on Aug. 8.604 UT the nova was photographic magnitude < 12, and 
on Aug. 31.38 visual magnitude 10.5. D. A J. Seargent, The Entrance, New South 
Wales, also obtained visual magnitude 10.5 around the same time. R. H. McNaught 
reports that no star appears in the position of the nova on the first Palomar Sky 
Survey Blue or Red plates. The pre-nova was recorded on UK Schmidt plates on 
September 6, 1980, at magnitude(R) - 20; May 3, 1981, at magnitude(J) - 21; and 
August 23, 1984, at magnitude(R) - 20: (IAU Circular 5332)

Please use the accompanying AAVSO charts prepared by Charles Scovil to observe the 
nova, and report your observations to AAVSO Headquarters.

Our congratulations to Paul Camilleri on his third discovery this year!

REQUEST TO MONITOR DWARF NOVAE FOR IUE OBSERVING RUNS

Astronomers in the Netherlands have requested our assistance in monitoring dwarf 
novae for their upcoming IUE observing run on dwarf novae in outburst, scheduled 
for September 16-17, 1991. Please call in your observations of dwarf novae in 
outburst September 13, 14, 15, and 16 so we may update the astronomers before and 
during their observing run.

The Headquarters answering machine (617-354-0484) is on nights and weekends for 
your convenience.

Many thanks for your observing efforts and your valuable astronomical contributions.

Good observing!

Janet A. Mattei
Director
