Observers:

Two new equipment systems are available and one will be tested this trimester. 
(1) The SAO/UMass NICMOS-3 detector had a successful engineering run in March; 
it will be upgraded in Septimber and will be available thereafter.  
(2) The SAO/Harvard fast piezo scanner was successfully tested in June;  
it will be available this trimester.
(3) The French NICMOS-3 detector for FLUOR will be tested in October. 

The infrared table was upgraded in March with full-sized optics, including a 
new JHK beamcombiner plate and compensator, and a 6 inch diameter, 24 inch 
focal length parabola to focus the beam onto the SAO/UMass NICMOS, or with 
some extra work onto any other infrared detector.  The visible table is 
unchanged, except for the addition of the fast piezo scanner, which can also 
be used on the infrared table.
 
Allocated time starts at the beginning of the first date indicated, and stops 
at the end of the night on the last date, i.e., sunrise the next day.  
For dorm reservations call Ginnee Larson at the base camp, 520-670-5701.  
Each observer group is responsible for its own baseline changes and equipment 
readiness.  

Contact Marc Lacasse at lacasse@cfa.harvard.edu, or telephone 520-670-5750 
(Tucson office), or 520-670-6757 (IOTA site) for any special requests or 
general information.  Please remember that Marc's prime responsibility is the 
development of IOTA as a facility, and that assisting observers comes second.

Damien Segransan will be assisting Marc and generally working to upgrade IOTA, 
from July 1997 to August 1998, inclusive.  We thank our French colleagues,  
their government's CSN program, and Aerospatiale for Damien's presence.

Anything that each observer can do to improve the next observer's experience 
(equipment notes, operating tips, computer programs, etc.) is always much 
appreciated.  Short observing reports are likewise appreciated;  reports 
received from the past trimester will be collected and emailed to active 
observers in the near future.   
As always, comments are welcome (traub@cfa.harvard.edu).  

Wes Traub and Nat Carleton
