Every evening on the ship we received a newsletter filled with information about the next day. They listed activites on board and posted info on the island we were visiting as well as arrival and departure times. They also noted what time the sun would rise and set. Fortunately for me, my husband is an early riser, so I got to see the sun rise several times during the week.
The thing I want to know is, how do they know when the sun is going to rise? What I mean is, how can they say it will rise at 6:13 a.m. when the rising of the sun is such a glorious and gently unfolding process?
Has the sun truly risen when you are sitting in total darkness and you see the first small ray of light at 6:13 a.m.? Or has the sun officially risen when all the darkness has dissipated at 6:13 a.m. and there is only light that is visible?
