Thanks Turtle, this makes the 5th moon rise time I've found. Do you have any personal experience to see how accurate this one is? I would think the Moon rise can be predicted to the minute at least if not the second.

no experience with that link, no. my gps gives moonrise/moonset too, but i don't know about accuracy. curious why you need exact time?? just curiosity, or is there a specific need i can't fathom??? :) gotta run; be back later today. . . . . . :doh:

I have been asked to recite a poem I wrote at the rise of the Red Moon on October 4th by a group of Pagans. (Harvest Moon for all you non Pagans :doh:) There has been considerable disagreement as to the actual time of the Moon rise. The first time I received was 19:05, another said 16:59, another was 18:20, another said 17:59. Yours said 18:48

There are two moon rise times. One is the astronomic time, the physical presence of the moon over the horizon. The other is the optical time, the image of the moon appearing over the horizon given atmospheric refraction. The moon is optically visible before it is physically present.

Ok, I can see that but how much difference is there between the two? I have a range here of 2 hours.

 

not sure about your question to Al; will let him field that.

 

your exact longitude matters though and i don't see the charts considering that. not sure if the gps takes exact longitude into account either beyond a time zone. each time zone covers 15º of longitude, but the actual distance encompassed in that 15º depends on your latitude. worth mentioning the obvious i guess, which is each 15º time zone is 1 hour. then there is the matter of what kind of horizon you have at your location, that is to say, intervening hills or flat to the horizon. the "exact" times of moon phases in astronomical tables is given for the moon at the zenith. not any help but gotta give what i got. :lol:

 

often local tide books give moon rise/set for hunters & fisherman. try that too. :clue:

i never go beyond this front page for my moon phase data, but they may have some links to rise/set info. :) :) >> Moon Phases :: Calendars

 

ps just found this: Moonrise and Moonset Calculator

The U.S, Naval Observatory, Astronomical Applications Department has a page where you put in the date and the location you want to know. Then it tells you Moonrise time, moonset, ETC. as well as sunrise, etc. It tells you the Latitude and Longitude for the location you've entered. It even tells what % of the "Moon's visible disk" is illuminated. Simple to use. I just used it and it was consistent with what I observed tonight when I was out checking out the "harvest moon".
