Although it was comparatively hazy in lower west skies, I could take a structure of dust tail with a length of a bit longer than 20 arc minutes. The first and second images have been displayed by turning celestial north direction and the zenith upward, respectively. You can recognize some fine stars in the constellation of Pisces in the first image. We will be able to appreciate clearer figure of the comet after next week when the comet is observable after end of twilight.
