Reports from Geisei Observatory <May 23, 2009>

C/2009 F4 (McNaught), C/2009 F5 (McNaught), and C/2009 F6 (Yi-SWAN)

The following are the observations of relatively faint comets in the southern sky. Because of the slow optics of Geisei's 70cm telescope, I often provide the magnitudes of the nucleus.
C/2009 F4 is at a great distance from the earth and the coma appears very small.
