Marine Astronomical Navigation - Video 21: Twilight & Travel Time of Heavenly Bodies
Celestial Astronomy is a very interesting subject if understood in a correct way. The teachers are responsible in a big way to make it interesting or otherwise. Even the non mariners might find this subject interesting. Capt. S.S. Chaudhari, who has been teaching the subject for last 30 years, works on this series of videos to share his knowledge and motivate the young marines. Capt. Chaudhari in this video explains about the daily apparent motion of Sun & Moon caused due to spin of the Earth, including the transit time. He also explains about the Twilight & the method to calculate the same.
