- The crescent is expected to be seen by optical aid only from the areas located under the blue color.
- The crescent is expected to be seen by optical aid from the areas located under the magenta color.. In these areas the crescent could be seen by naked eye if the atmospheric conditions are superb and the observer is experienced.
- The crescent is expected to be easily visible by naked eye from the areas located under the green color.
- The crescent can not be seen from uncolored areas, even though the Moon rises in these locations before the Sunrise and the topocentric conjunction occurs after the Sunrise, but the Moon is not sufficiently illuminated in order to be seen as crescent even by optical aid.
- Kindly notice that the below graph shows the possibility of seeing the crescent from areas between 60 degrees north of Equator down to 60 degrees south of Equator.
