Proposal Title: OH Observations of four comets June 2011 ­ January 2012
ABSTRACT:
We propose to continue our measurements of OH lines in cometary comae to measure the water production rates,
outflow velocity and study e#ects of collisional quenching in the inner coma. The radio lines at 1667 and 1665 MHz
are ideally suited for study of water in comets from the ground, and can be done in daylight. Two short­period
comets and two long­period comets are available in this time period.
