COMET C/2006 P1 (MCNAUGHT)
Andrew Pearce reports the comet at m1= -2.1 on January 18.50UT with coma 
diameter 1 arcminute and DC 9 as seen to the naked eye from City Beach, 
Western Australia. A tail of 4.5 degrees length was visible to the naked 
eye in PA 140deg. On January 19.51UT, the magnitude had apparently 
decreased to -0.4, diameter 1 arc minute, DC 9 again with the naked eye.

In a further report for 2007 Jan. 20.51 UT he estimated m1 at -0.7, 
diameter 1 arc minute, DC 9 to naked eye. The central condensation is 
apparently non-circular slightly elongated to the ENE. The straight line 
measurement from the coma to the southern edge of the tail at the 
extremity is 23 degrees but may be even longer.

Correction: In TA E-Circular 2300, m1 for Jan 17.50UT should have read 
-2.7 and not 2.7.
