Dear Colleague,

This is our final mailing prior to the First Annual Conference on
Astronomical Data Analysis Software and Systems to be held in Tucson,
November 6-8, 1991.  The meeting is being sponsored by the National Optical
Astronomy Observatories (Tucson, Arizona), the Smithsonian Astrophysical 
Observatory (Cambridge, Massachusetts), and the Space Telescope Science
Institute (Baltimore, Maryland), and is being hosted by NOAO.  The Program
Organizing Committee would like to thank NASA and NSF for their support of this 
Conference by providing special grant monies.

A preliminary Conference program along with a list of Conference participants 
is enclosed.  41 oral papers are scheduled during the general session.  80 or
more poster papers and demos have also been scheduled.  Several special

publication is enclosed.

There will be a Conference reception at the Radisson Hotel the evening of 
November 5, from 7-9pm.  Light snacks will be provided and a no-host bar will 
be available.  We hope you can join us Tuesday evening to say hello and to meet
with other Conference participants.
