I have captured the comet Boattini for the first time in last two months in lower dawn skies. In that day the comet has been positioned at western edge of Taurus near a border to Cetus with a coma brightness of about 6th magnitude. And we can detect an indistinct tail stretched toward southwest in this image. The comet will leave from the Earth from now on, but we can observe the comet easily because its elevation will rise in July and August 2008.
