Full description

The time of beginning or ending penumbral eclipse is simultaneous around the country but a place of beginning total eclipse differs from pace to place. The Moon Book will show you the phases of the moon eclipse at your place. You will be able to set up any observing place beforehand if the moon eclipse star chart is selected. When you move to a distant place for observing the moon eclipse, you will be able to know in advance a place where the Earth’s shadow starts hiding the moon. You will be able to check a start time of the moon eclipse overseas also. Tapping on the moon icon at the upper left corner of the star chart will show you thumbnail images of the phases of the moon eclipse at regular intervals. The interval of the thumbnail images can be changed. A large volume of calculation is required for the indication of the moon eclipse and it will be better to use a terminal device with performance as high as possible. For Android, version 4.0 or later is recommendable.
