All:

After more than a decade of productive life, GRIM2 will be permanently 
retired from service at APO on 18 April 2005.  Many important science 
results from the 3.5-m and SDSS telescopes are based on GRIM2 
observations, and in its early years it produced more scientific 
publications per telescope observing night than any other 3.5-m 
instrument.  In its prime, GRIM2 had unique capabilities that helped 
further our understanding of planetary atmospheres, cool stars, and 
other important areas of ARC research, as well as graduate student 
training and research.  On behalf of the ARC community, we thank Al 
Harper, Mark Hereld, Bernie Rauscher, Bob Loewenstein, Dale Sandford, 
Don York, and the many other staff members at Yerkes Observatory and 
the University of Chicago who built and commissioned the instrument, 
and those who helped keep it running over the years.

GRIM2 is the progenitor of its replacement instrument, NIC-FPS, a 
University of Colorado instrument that features a current-generation 
NIR detector with lower noise and a wider field of view.  The 
disposition of GRIM2 is presently under discussion; if you have an 
interest in acquiring GRIM2, please communicate your interests and your 
intended use of it to the undersigned.
