Abstract

Ground-based observations of Comet Halley [OI]6300 were carried out using the Wisconsin dual-etalon Fabry-Perot spectrometer at the McMath solar telescope on Kitt Peak. The field of view diameter on the sky was approximately 7′ preperihelion and 10′ postperihelion. Spectral scans were acquired at a resolution of 0.2 Å, which was sufficient to resolve cometary [OI]6300 emission from nearby cometary NH₂ and telluric [OI]6300 emissions. From these measurements, we determined the production rate Q(O(¹D)). By taking into account photodissociation of H₂O and OH as sources of O(¹D), we find that the ratio Q(H₂O) Q(O(¹D)) is 6 and obtain Q(H₂O) from our Q(O(¹D)) measurements We compare our Q(H₂O) results with measurements by other groups.
