       70 degrees. Comet easily visible with the naked eye as a very condensed, apparently
       stellar object. No tail visible with the naked eye, in 10x50B comet very condensed
       with a prominent 1.5 degree tail. Comet situated in the zodiacal light, so the 
       faintest parts of the tail and the coma may have been drowned out by the bright 
       background. Extreme Bobrovnikoff method, as suggested by John Bortle.]
