The comet Itagaki in that day has been positioned in northern region of Aries, I could detect a 10th magnitude coma same with that in last week. This image has been captured in twilight because the comet is closing to the sun. And you can see a dimmed and thin tail stretched in northeast direction with a length of about 10 arc minutes.
