## Comet McNaught-Hartley was observed in five 1-h exposures on January 8-14 2001 using the advanced CCD imaging spectrometer on board the Chandra X-ray Observatory. The X-ray image of the comet does not show a crescent-like shape. The brightest region is offset from the nucleus between the sunwar

using the broadband array spectrograph system on the IRTF. The spectrum showed a silicate emission feature extending about 20% above the continuum. Two emission features at 10.3 and 11.2 µm appeared above the silicate band, the latter seemingly indicative of crystalline olivine. The 10.3-µm feature
We report on high spectral resolution observations of Comet C/1999 S4 (LINEAR) obtained at McDonald Observatory in June and July 2000. We report unequivocal detections of the O ( 1 S) and O ( 1 D) metastable lines in emission in the cometary spectrum. These lines are well separated from any telluric
