The following diagrams show the global visibility of the new crescent Moon over the first three days of the lunation. These diagrams are based on the current model for predicting the visibility of the crescent moon using the Yallop criterion described in HMNAO Technical Note No. 69.

Within the area of purple diagonal striping (if shown), the new crescent moon cannot be seen as the instant of new moon has not yet occurred. The moon sets before the Sun within the area of the peach-coloured shading (if shown). The unshaded area, F, indicates the region from which the new crescent moon cannot be seen — the thickness of the crescent is too thin to be seen i.e. it is beyond the Danjon limit. In the dark blue shaded area, E, the new crescent moon is not visible with a telescope and in the pale blue shaded area, D, optical aid of some sort will be needed to see the new crescent moon. In the pale yellow coloured area, C, you may need optical aid of some sort to find the new crescent moon initially. In the yellow shaded area, B, the new crescent moon should be visible under excellent atmospheric conditions with the naked eye and finally, in the red shaded area, A, the new crescent moon should be easily visible with the naked eye.

The near vertical curved lines labelled 0, 2, 4, 6 etc., show the age of the moon in hours at the "best time" of observation, defined in HMNAO Technical Note No. 69 as 4/9 of the time difference between sunset and moonset or the time of sunset plus 4/9 of the "lag time". The instant of new moon is given below the diagram. The age of the moon at its first visibility with a telescope and also with the naked eye are given below the diagram where appropriate. A key describing the annotation and shading is given beneath each diagram.

The following diagram shows the visibility of the new crescent Moon on 2018 November 07.

The second diagram is for 2018 November 08 and exhibits more shaded regions than those found in the map for 2018 November 07. Consequently, a larger fraction of the surface of the Earth will be able to observe the crescent Moon with ease.

The third diagram is for 2018 November 09 and is almost totally shaded in red. The majority of the Earth will be able to observe the crescent Moon with ease. Those regions outside the red zone will have to wait until the following day to make their sightings.

Global Visibility Maps for previous months
Several requests have been received suggesting that we make available the global visibility maps for previous new crescent moons. The following table contains links to the visibility maps (in pdf format) for the first three days of each lunation from January 1990 to the latest new moon. You will see a thumbnail of the visibility map if you move your cursor over the links. Clicking on a specific link will bring up a pdf version of the relevant visibility map. You may need to do a "rotate clockwise" on it to re-orientate the pdf file horizontally.

Links following a in the table below indicate dates on which Ramadan may start i.e. a naked-eye sighting of the new crescent moon may be possible under excellent conditions. Similarly, links following a indicate dates on which Ramadan may end.
