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.
