The comet 2013R1 Lovejoy in that day has positioned at about 4.5 degrees northwest of gamma Bootis. The comet started to go away from the Earth but approaching to the sun, I could observe the coma of almost same brightness of 4th magnitude with my previous observation. The images can show us that the comet has a well-evolved ion tail with several stripes.
