The US Navy uses the following dates to track the primary phases of the moon:
Sept 23 Calendar - Coral Dierdre
New Moon: This phase occurs when the moon is positioned between the Earth and the sun, making it invisible from our planet. The new moon typically occurs on the 1st, 29th, or 30th of the month. First Quarter: This phase occurs when the moon has completed one-quarter of its orbit around the Earth, making it visible in the western sky after sunset. The first quarter typically occurs on the 7th, 8th, or 9th of the month. Full Moon: This phase occurs when the moon is on the opposite side of the Earth from the sun, making it fully visible all night long. The full moon typically occurs on the 14th, 15th, or 16th of the month. Last Quarter: This phase occurs when the moon has completed three-quarters of its orbit around the Earth, making it visible in the eastern sky before sunrise. The last quarter typically occurs on the 21st, 22nd, or 23rd of the month.

Importance of Lunar Cycles for the US Navy

Understanding lunar cycles is crucial for the US Navy, as the phases of the moon have a significant impact on the tides and ocean currents. The navy uses this information to: Predict Tides: The US Navy uses lunar cycle data to predict the tides, which is essential for navigation and ship operations. Plan Missions: The navy takes into account the lunar cycles when planning missions, as the phases of the moon can affect the visibility and stealth of naval vessels. Conduct Research: The US Navy conducts research on the lunar cycles to better understand their impact on the ocean and atmosphere. In conclusion, understanding the primary phases of the moon is essential for the US Navy, as it has a significant impact on the tides and ocean currents. By tracking the lunar cycles, the navy can predict the tides, plan missions, and conduct research to better understand the ocean and atmosphere. Whether you're a sailor or just interested in astronomy, understanding the lunar cycles can help you appreciate the beauty and complexity of our universe.
