The Cycle 5 HST program on comet Hale-Bopp (C/1995 O1) has proposal number
5844 and was allocated 11 orbits of HST observing time. The original
plan was to spend 9 orbits doing spectroscopy and 2 orbits doing imaging
observations. However, that strategy might be modified pending a review
of the initial results.

The images will be used to place constraints on the size of the nucleus,
to investigate the morphology of the inner coma, and to provide target
acquisition support for the spectroscopic observations.

Deep UV spectra will be obtained to search for CO2 (via emission in the
CO Cameron bands), CO, OH, and other species having emissions in
the 1295 to 3277 Angstrom region. The spectral resolving power of
these observations is roughly 1500.
