Work during the second quarter of 1997 consisted of many smaller tasks. Due to 
modifications in CONSTRICTOR regarding the computation of the laser jitter 
while tracking fringes with NPOI, some of the old raw data had to be re-reduced.

With respect to my scheduling responsibilities of NPOI observations, I added
a few procedures to the pool of data reduction scripts to facilitate the 
scheduling. This also included improved data base routines to get an overview 
of past observations on a given star.

A final calibration of the data on two limb-darkened stars, Alpha Arietis and 
Alpha Cassiopeiae, was completed, and diameters fit to the data for publication.
(The paper is written up by A. Hajian.)

I completed the calibration of the Mizar A data and fitted an orbit to the 
measurements. Due to problems with the calibration, results are preliminary.
I have begun the same process for Omicron Leonis. Also in this case, enough 
data were gathered with NPOI for an orbital solution.

I visited NPOI for one week for data analysis, help with debugging of embedded 
system astrometry, scheduling of observations, etc. From Flagstaff, I drove to 
Socorro, NM, to attend the IAU colloquium 164, "Radio emission from galactic 
and extra-galactic compact radio sources". I presented poster on "The radio jet 
of quasar 0153+744". I wrote a two page contribution to the proceedings.

My proposal, "Stationary jet in quasar 0153+744?" to the VLBA was not given 
time by the referees, but I re-submitted it with modification since I strongly 
disagreed with the reports.

I processed more than 42 nights of data through CONSTRICTOR and (partly)
CHAMELEON, many with only a preliminary calibration. I had prepared schedules
for each one of them.
