The comet 2009P1 Garradd in that day has been positioned at about 3 degrees northwest of a globular cluster of M15 in tip of the nose of Pegasus. The comet has a coma brightness of about 8th magnitude and a short tail in southeast direction. I could appreciate the comet paralleling with M15 through a binocular.
