摘要：

COHSI (the Cambridge OH Suppression Instrument) was successfully commissioned at the United Kingdom Infrared Telescope on Mauna Kea during a seven night observing run (19,20 & 25-29 March 1998) which coincided with this conference. Here we briefly describe the instrument and give a preliminary report on its performance at this time. The suppression optics and masks worked extremely well and the instrument background was found to be very low.
