This page shows you images of comet Holmes captured at suburb from Tokyo for the first time in last a week. The comet has a coma with a size of larger than 10 arc minutes, and I have estimated the visual brightness of about 2.5 or 3.0 in magnitude. I could detect a dimmed light of comet only with my own naked eyes. And it's considered that the comet has a short dust tail in southwest direction.
