The comet 2014Q2 Lovejoy in that day has positioned between Andromeda and Perseus, I could observe the coma with a visual brightness of about 5th magnitude. Although the ion tail looks dimmer than that in last month, a length is keeping a bit shorter than 10 degrees. And in that day the comet was lying about 3.3 degrees south of a bright planetary nebula of M76.
