The paper presents results of observations of comets C/2009 R1 (McNaught) on June 14–28, 2010 and 17P/Holmes on November 6–10 and November 25 – December 3, 2007 in the line of OH molecule at 18 cm. The OH gas production rate of comet C/2009 R1 (McNaught) versus the heliocentric distance between 0.42 and 0.62 AU is estimated.
