The phase of the Moon before a solar eclipse is the waning crescent phase. This phase occurs just before the New Moon phase, which is when a solar eclipse can take place. In the waning crescent phase, the Moon is illuminated by sunlight on the side facing away from Earth, making it appear as a thin crescent shape.

A solar eclipse happens when the Moon passes directly between the Earth and the Sun, blocking the Sun's light. This alignment can only occur during the New Moon phase. Therefore, the waning crescent is the final phase leading up to this alignment, signifying that the Moon has been transitioning from the Full Moon phase, where it is fully illuminated, through the waning gibbous and third quarter phases, and finally to the New Moon.

In summary, the waning crescent phase is the last visible phase before the Moon reaches the New Moon and the opportunity for a solar eclipse.
