Visibility II / V

I finally managed to make a decent observation of the Iwamoto comet. Only the comet's coma was visible and under these conditions it too appeared with difficulty and very dim. The coma only brightens slightly towards the center. No central clearing or visual tail is observed. Coma diameter about 5 ', degree of compaction 2.
