Mars 2020-12-28 (UT)
In the evening, Mars moves southward, so it overlaps with my daily life and I am busy. The feature of Mars is around 0 degrees longitude, and the appearance of the feature pattern has returned to its original state. The apparent diameter of Mars is now 10 arcseconds. It will continue to be observable in the evening sky until April next year (diameter 5 arcsec), but it will be severe in winter when seeing condition is bad.
