Abstract
Observations of Comet Halley were made with a large-aperture, double-etalon Fabry-Perot spectrometer at the McMath solar telescope on Kitt Peak, Arizona. Approximately 900 scans of H 2O +, Balmer alpha (Hα), [0I] 6300, and NH 2 emissions from the comet were obtained between 15 November, 1985 and 10 May 1986. This paper presents the objectives of our program, an instrument description, examples of data, and a short summary of preliminary results.
