🔍 Key Concepts

• Equation of time and the difference between apparent (sun) time and mean (clock) time • How we find Local Apparent Noon (LAN) when doing a meridian passage sight • What kind of "time" is printed directly in the Nautical Almanac vs. what must be corrected

💭 Think About

• Ask yourself: does the equation of time convert clock time to time zone time, or does it adjust between sun time and mean time? • Think about the steps to find the time of meridian passage (LAN) at your longitude: where in that process does the equation of time come in? • Which of the choices would logically depend on the irregular motion of the Sun in the sky over the year, which is exactly what the equation of time corrects for?

✅ Before You Answer

• Verify which type of time the meridian passage page of the Nautical Almanac is referenced to, and how the equation of time modifies it • Check that zone time comes from longitude and standard time zones, not from the equation of time • Confirm whether sunrise times in the Nautical Almanac are already corrected, or if they require using the equation of time separately
