The observing condition of comet PanSTARRS is getting better and better day by day, I could recognize the dust tail with a length of about 30 arc minutes and could detect the coma with naked eyes for the first time. The second set of images have taken sinking comet beyond forest in west. I could appreciate only dust tail stretched from the trees after the coma has set.
