✦ Synopsis


We have monitored the 1 10 -1 01 pure rotational transition of water vapor near 557 GHz toward Comet C/1999 H1 (Lee) over the period 1999 September 5 through 1999 December 8, using the Submillimeter Wave Astronomy Satellite. The measured antenna temperatures implied water production rates that declined from 3.2 × 10 28 s -1 on
