! Thanks for the info, Dave.

Is there an explosion?

I tried in the morning of 12th Jan by a small telescope (65mm in dia, focal length 420mm and 25mm eyepiece with magnification of 16.8), but failed. Might be due to the light pollution or fog...However can find it from the photo with 500D connected to the telescope (2s exposure, ISO 12800). Waiting for another clear night.

Cheers
Guodong
