Lunar Images

A new crescent moon can be very difficult to see with the unaided eye on the 29th day of the lunar month.

The following images tell you the age and altitude of when the new moon was first spotted by one of our astronomers (Charles Evans).

All of these images were taken through telescopes, 18 to 30 minutes after sunset.

Seeing a new crescent in the first ten minutes after the sunset is nearly impossible. The human eye cannot discern the contrast between the bright background and the new crescent.

   
 

 

Challenge

Crescent observers who claim that they spotted a crescent moon before sunset or within 10 minutes after sunset should show proof with pictures. This means a picture of a crescent with the sun in it as well if it is before sunset. Digital cameras all now have time stamps to verify the time of the image, so we can also tell how long before or after sunset the image was taken.

If the crescent moon is not observed at places located west of the initial observer then it proves that the initial observation was incorrect.

When the sun rises in New York, every person sees it to the west of this. This is the same case with the crescent moon.

It is highly unlikely that only one or two observers will see the new crescent moon only to have it disappear for everyone else who is trying to see it from the same place or places west of them.
