This image shows you the comet Itagaki 7 days later of its discovery. I could detect a clear bluish coma with a beightness of 10th magnitude. Although any tails could not be detected, a coma has a bit fan-like structure spread in southern direction.
The comet Itagaki will close to the sun and be dimmer from now on, cannot be observed in April 2009.
