The interstellar comet Borisov a week later from my previous observation positioned at northeast region of Sextans in dawn southeastern skies. The coma's brightness could be estimated about 16th magnitude as with a week ago, and I could firstly capture a dimmed dust tail stretched in northwest direction. It can be seen that the comet's activity is getting higher by closing to the sun. The comet Borisov will move southward from now on, we can chase it until the end of 2019 at northern hemisphere.
