The following diagrams show the visibility of the
new crescent Moon over the first three days of the lunation. The
unshaded areas indicate regions from which the Moon cannot be seen.
The Moon becomes more easily visible from the regions of increasing
colour intensity i.e. the Moon will be seen easily from the regions
shown in red. The near vertical blue lines show the age of the Moon
at the so-called "best time" of observation. The following diagram shows the visibility of the new crescent Moon on 2012 January 23. |

The second diagram is for 2012 January 24 and exhibits more shaded regions than those found in the map for 2012 January 23. Consequently, a larger fraction of the surface of the Earth will be able to observe the crescent Moon with ease. |
