PROBABLE NOVA IN SAGITTARIUS

The Central Bureau for Astronomical Telegrams informs us that F. Bateson of the 
Royal Astronomical Society of New Zealand reported, via A. Gilmore of Mount John 
Observatory, the photographic discovery of a probable nova by P. Camilleri, 
Cobram, Victoria, Australia, on July 29.406 UT at magnitude 8.5. Gilmore reports 
the precise position (1950) of this object as:

	RA 18h 10m 58.12s	Dec. -32deg 13' 23.6"

The object has been confirmed visually, and appears to be fading quite quickly, 
as the following observations indicate:

July	29.504 UT 	7.0 W. Goltz, Tarnagulla, Victoria, Australia 
	29.505 		7.3 P. Williams, Heathcote, NSW, Australia 
	30.096 		7.9 J. Bortle, Stormville, NY
	30.33 		8.2 A Jones, Nelson, New Zealand
	30.37 		8.1 A Jones
	30.438		8.1 D. Seargent, The Entrance, NSW, Australia 
	30.45 		8.5 P. Williams
	30.46 		8.2 A Jones
	30.46		8.6 T. Tregaskis, Mt. Eliza, Victoria, Australia
	31.090 		8.4 J. Bortle
	31.90		9.5 A Pereira, Cabo da Roca, Portugal
Aug 	1.156		9.4 J. Bortle

Please use the accompanying AAVSO charts to observe this object, and report your 
observations to AAVSO Headquarters. When the nova falls below the limiting 
magnitude of the "b" chart, please use the VZ Sgr "e" scale chart until a "d" 
scale chart is prepared for the object.

Our congratulations to P. Camilleri for his discovery!

SPECIAL MULTIWAVELENGTH MONITORING OF 0201+14 IT ARIETIS

Many thanks to those observers who are participating in the coordinated 
multiwavelength observing of IT Ari on August 1-2. Please submit your observations 
of IT Ari to AAVSO Headquarters. For visual observers, please report your the 
time of your observations to the minute (4 decimal places of the JD). For photometric 
observers, please report the time of your observations to the second (5 decimal 
places of the JD).

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

Janet Mattei, who is in Buenos Aires, Argentina, attending the General Assembly
