Abstract:
The spectrometric observations of Comet C/1996 B2 Hyakutake were taken on six nights at its closest approach (March 23-April 09, 1996), with 104 cm telescope of the Naini Tal Observatory, using EG&G Spectrograph coupled with Optical Multi Channel Analyzer and Reticon Array Detector. The molecular emission bands of CN at 3888 Å, and C2 (Δv = +1, 0, -1) at 4690 Å, 5160 Å, and 5530 Å respectively, were detected. Column densities and production rates at different heliocentric and geometric distances were also determined.
