About Comet Book

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.

... the autoscrolling is not too smooth. Not of a big deal, though. I was able to see Comet Lovejoy accurately because of this app.

The developer is a Japanese maker of optical instruments. It will be interesting to see how often they update this with new comets. User guide is online, accessible right from the app.
