April 17, 1991: The Moon's Phase
On April 17, 1991, the moon was in the waxing gibbous phase. This means that the illuminated portion of the moon was increasing in size.
Understanding the Moon's Phases
The moon's phases are a result of the changing angles at which we, on Earth, see the sunlit portion of the moon as it orbits our planet. The moon itself doesn't produce light; it reflects sunlight.
Here's a breakdown of the phases:
- New Moon: The moon is invisible as it is positioned between the Earth and the sun.
- Waxing Crescent: A sliver of the moon becomes visible on the right side.
- First Quarter: Half of the moon is illuminated, appearing as a half-circle.
- Waxing Gibbous: More than half of the moon is visible, and the illuminated portion continues to grow.
- Full Moon: The entire moon is illuminated, appearing as a full circle.
- Waning Gibbous: The illuminated portion of the moon begins to decrease, still appearing larger than half.
- Last Quarter: Half of the moon is illuminated, appearing as a half-circle again, but on the opposite side from the First Quarter.
- Waning Crescent: A sliver of the moon remains visible on the left side, and it continues to shrink until it reaches the New Moon phase again.
Historical Significance of April 17, 1991

However, it is interesting to note that the 1991 Persian Gulf War officially ended on April 17, with a ceasefire agreement. The moon's phase that day was a reminder of the cycle of life, even in times of conflict and resolution.
