Comet C/2021 A1 (Leonard) Sky Path in 2021

At discovery on January 3, 2021, new comet C/2021 A1 (Leonard) was located in the northern constellation of Canes Venatici (CVn) and moving northward in that constellation in January 2021.
For most of the year 2021, comet C/2021 A1 is expected to remain at high northern declinations. Depending on your latitude, the comet may be circumpolar, remaining above the horizon and never setting. Like many comets arriving in the inner solar system from beyond 5 au, the apparent sky path spirals around a point in the sky from where it came at much greater distance.
Comet C/2021 A1 (Leonard) will move through Canes Venatici and into Ursa Major for much of 2021 returning to Canes Venatici in November 2021. Sky motion will increase as it gets closer to Earth just like all solar system objects. Comet observers in the northern hemisphere have the opportunity to watch it brighten many magnitudes and perhaps to at least 4th magnitude in the second week of December 2021 as it passes 0.233 au from Earth.
