Tropical Moon
Which of the images are possible views of a moon near the horizon (either rising or setting) close to the equator?
The top four images represent daytime, and the bottom four nighttime. The phase of the moon is not necessarily consistent across the images.

Number 3 could be either rising or setting with the sun overhead. (The rising option would be for a waxing moon, setting option for a waning moon).
Number 5 could also be either rising or setting, with the sun down below the horizon. (The rising option for a waning moon, setting for a waxing moon).
Those two images are the only views possible.
2 , 4 , 6 , and 8 would require the sun to be near the horizon in the north or the south, neither of which is possible in the tropics.
Number 1 would have the sun below the horizon in daytime, while 7 would have the sun overhead at night.
