โฆ Synopsis
Spectrophotometric observations of Comet Austin (1982g) in the bands of CN, C,, and C, are presented, and fit to a Haser model for the cometary brightness distribution. The lifetimes of the parent and daughter molecules, as well as the velocity of the molecules leaving the cometary surface are determined from the model fit. The absolute production rate of molecules is also determined.

Spectrum scans have been obtained of the head of Comet Austin on six nights at heliocentric distances (r) from 0.70 to 0.87AU. The useful spectral region is h&330-750nm. Strong emission features of CN (388nm) and Swan band sequence of C, (474, 516, and 563nm) were identified. Weak emission features
Spectrophotometric observations of the head of comet Austin (1989 Cl) during five nights in May 1990 are presented. Emission bands due to CN, Cz and C3 molecules have been identified. An estimate of their column densities and production rates have been made.
Positions of Comet Halley have been measured from the photographic plates taken at Cassegrain focus of the 104-cm telescope of Uttar Pradesh State Observatory.
