Latitude by meridian altitude (Meridian Passage) - Moon as a celestial body

[@Otesego_Genesis666]

Hi. We do not take upper merpass time because moon UL is given. We take upper merpass because it passes observers prime meridian. Even if moon LL was given we take upper merpass time as it will still pass the obervers prime meridian. If it was given moon passes obervers 180 deg long, that means, opposite of obervers meridian or obeservers inferior meridian only then we take Lower merpass time, thats why the upper and lower merpass time of moon have approx 12 hrs diff everyday

Steps to Calculate LMP: Determine the UMP Time: Use the Nautical Almanac or similar reference to find the UMP time for the Moon on the given date. Add 12 Hours: Since the LMP occurs approximately 12 hours after the UMP, add 12 hours to the UMP time. Apply Longitude Correction: If the observer's longitude is West, subtract the longitude in time from the calculated LMP time. If the observer's longitude is East, add the longitude in time to the calculated LMP time. Example: If the UMP time for the Moon on a particular day is 12:30 PM GMT, and the observer's longitude is 60 degrees West: Add 12 hours to the UMP time: 12:30 PM + 12 hours = 12:30 AM (next day) Convert the longitude to time: 60 degrees / 15 degrees/hour = 4 hours Since the longitude is West, subtract the longitude time from the LMP time: 12:30 AM - 4 hours = 8:30 PM (previous day) Therefore, the LMP for the Moon for that observer would be 8:30 PM on the previous day.

Why HP are 55.8 there app alt 56.1 can u clear this?

[@TheTraderzz]

sir can u pls tell while doing exercise of latitude by meridian altitude moon question number 3 the answer of this question on book is write or wrong cuz in question they have given the value of LL of the moon so i have taken the value of LLbut answer on book value is computed by UL of the moon pls help regarding this one

[@nalinkashyap6008]

Thank you sir ❤

[@RaghvendraSingh-jg1bt]

Are the values given for upper transit merpaas time and lower transit merpass time of moon and UL OR LL ? Can you please verify sir?

[@TheTraderzz]

Sir i have a question what is gmt is given in the question and asking for latitude and PL.should i compute the azimuth for PL or just directly PL will be east nd west

Nice technique

[@alphamale4609]

Why lower merpass time is given for moon and not for sun?

[@jayasuryakrishna]

Tq so much sir ❤️

[@Guidingmariners227]

Didn't understand the hp correction??

[@sohaibshaikh5481]

Can you solve the longitude west one

[@shangfernz]

Hi sir can you make a video of corrections of altitude for moon

[@TheTraderzz]

Thanks a lott sir really much appreciated sirrr .let me know if i can do any kind help to increase this chanal up sir . Once again thank you sir.

[@SteeringMariners]

Faisal Qazi thanks Buddy 😊 just share the videos with your fellow mariners ....that’s all.

Why we take 55.8 in HP

[@sauravanand9100]

🙏🙏🙏🙏🙏

[@badhansaha21]

Sir how can we determine that the Sun is bearing south of me? And in case of UL corr. we are subtracting 30.0' but in case of LL, do we need to substract or add anything? And main correction and HP correction to be always added? This is some doubts that I'm having sir. I'll be highly obliged if you kindly explain me. Thanking you in advance sir.
