The comet Tuttle moving southward rapidly in that day has been positioned in southern region of Fornax. I couldn't detect the tails because of bad transparency condition in lower skies. The coma has a visual brightness of about 7th or 8th magnitude, fairly dimmed compared with it in beginning of Jan 2008. The comet Tuttle will not be able to observe at Japan on and after Feb 2008.
