Ground-based high spectral resolution measurements of Comet Halley in the 6300.3 A spectral region establish
this technique as a powerful and low cost method for determining cometary H20 production rates. A model
of the line profile to be expected from the 0
1D coma emission indicates that ground-based observations with
fields of view on the comet
