The moon you see a couple of hours before sunrise in the western sky is most likely the waning gibbous moon.

Here's why:

* Lunar Phases: The moon's phases are determined by its position relative to the sun and Earth. As the moon orbits Earth, the illuminated portion we see changes.

* Waning Gibbous: A waning gibbous moon is a phase where more than half of the moon is illuminated, but the illuminated portion is decreasing.

* Pre-Dawn Visibility: A waning gibbous moon is often visible in the western sky before sunrise because it is still high enough in the sky from its previous night's visibility.

Important Note: The specific phase of the moon visible before sunrise will vary depending on the date. To determine the exact moon phase, you can use a moon phase calendar or online tool.
