On this day, comet 2020V2 ZTF is located at the northernmost point of Cepheus, declination 85 degrees, and is only 4 degrees away from Polaris. Because the comet is passing near the celestial north pole, the direction of its tail has apparently changed significantly to eastward since my previous observation. The brightness of the coma was estimated to be 10th magnitude, the greenish ion composition could be clearly recognized. The nebula seen in the upper right of the field is part of the faint molecular cloud that spreads around Polaris.
