The comet Kushida in that day has been positioned in west of the Hyades, almost same with last week. I could observe a large oval greenish coma with a diameter of over 10 arc minutes. The coma has a brightness of about 9th magnitude, its distribution of ionic light looks a bit asymmetric. Perhaps the comet has a short dust tail in east direction.
