To make a prediction regarding the moon phase on December 15, we can refer to a lunar calendar. For December 2023, the phases of the moon are as follows:
- New Moon: December 12, 2023
- First Quarter: December 19, 2023
- Full Moon: December 26, 2023
- Last Quarter: December 5, 2023
Based on this information, the moon phase on December 15, 2023, would be a waxing crescent, as it is between the new moon and the first quarter.
However, since this specific option is not listed in your responses, if we must select one from the options provided, the closest phase could be identified as "third quarter," given that the last quarter phase would have been just before the new moon.
