In end of April 2004, I've captured the comet 2002T7 LINEAR in eastern lower sky in dawn light. The comet has a brightness of about 4th magnitude and an indistinct tail stretching about 1 degree. The sky was getting brighter and brighter, the comet vanished beyond morning light only after several minutes. The comet LINEAR passed the perihelion two days before, and will move to western evening sky, be a naked-eye comet with the comet NEAT(C/2001Q4) in May 2004.
And in that day, actually we could see another new comet of Bradfield (C/2004F4) in ENE lower sky. But unfortunately I couldn't catch it in camera because of some trees.
