Comet Book

By Vixen Co.,Ltd.

Open iTunes to buy and download apps.


The Comet Book APP clearly shows you when Comet can be viewed and which direction is it in.

The direction and elevation of Comet can change noticeably in a day due to its fast apparent motion. The moon and a bright planet may be convenient as a guide to find the comet though they have a large apparent motion, too.

This app determines where Comet is in the sky when it becomes visible at your observing site.

You can easily start your observation of Comet using Comet Book as a guide to the direction and elevation of the comet.
