As the Sun rises both the comet and the Sun make their way across the daytime sky. In the evening the Sun sets before the comet which is now visible in the NW sky. The comet is much nearer the northern axis of the Earth's rotation and therefore stays in the sky longer than an object at the celestial equator. Comet Hale-Bopp has two tails. Not at all.
Many comets have two tails.
Comet Hale-Bopp's twin tails just stand out more clearly and dramatically than most. Comet Hale-Bopp has a very beautiful twin tail presentation. More questions will be added later.
