Scientific paper

The 1667 MHz OH line of Comet Halley was observed during March and April 1986 with a 25-m radio telescope and a 128-channel autocorrelation spectrometer. The observed mean OH flux for 4 days was -2.4 Jy. The measured OH expansion velocity was 0.92 km/s when the heliocentric distance was 1.39 AU. It was found that the profile asymmetry may be characterized by the first order moment of 0.20 km/s. The mean OH parent production rate was 1.7 X 10 to the 29th mol/s, assuming Haser's (1957) model with the parameters defined by Despois et al. (1981).
