Here are the L5 luminosity versions. L5 is probably not an accurate representation. But L1...
?
according to the troubleshooting Flight 1 form, there are 10 different moon textures, I have to find out what happen to my moon :banghead: I probably whacked something out messing with the weather, I will show the 4 or 5 pages of weather so we can be sure it's the best setting we can get.
it has seasons, turbulence, dew points, barometric pressure, different clouds, wind direction, temp, rain settings, snow, icing setting etc etc. I'm sure I left a bunch out.
For future porposes, if nothing else, I'll add this containing the search terms lunar, moon, phases, lunar phases and moon phases.
By searching these terms you’ll probably discover that the question has never really been answered properly in any of the simulator sites, or at least I didn’t find one that gave me a satisfactory answer.
I found this on the Flight 1 form:
So let me take a shot at some facts here:
The internal clock for scenery in FS2004, no doubt, was finalized sometime in 2003. By setting the time and date for the calendar year of 2003 and flying FS9 the phases of the moon were correct. I'm not sure, but I'd guess it would be a more recent date in FSX, depending the the year MS finalized the package.
Without going into great detail I did some research. I'm not a rocket scientist, but I do love navigation in the flight simulator.
First of all, one rotation of the earth is slightly less than 24 hours and one year, measured by the Roman calendar is slightly less than 265.25 days and never changes by more than a second every few years. I won’t go into that here. Secondly, the moon very accurately rotates around the earth approximately every 27.3 days. And thirdly, the moon’s phases vary from 29.272 and 29.833 days however the “mean number” for this can’t be accurately computed because the variations are much more complex.
It soon becomes obvious that the developers of MSFS 2004 decided to calculate the rise and set times of both the sun and the moon and leave the phase calculations alone. As I said above, if you check any year in FS9, and I went all the way up to 2030, you’ll find that the rise and set times are very accurate for both the sun and the moon.
David OPA Marshal says there are 10 textures for the moon in FS9’s scenery. I’m not sure why, since FS9 only displays the first crescent, first half, full, last half, last crescent and new moon, unless there are some different daytime textures?
The phases of the moon do not increase and decrease incrementally each day, but instead changes on dates which are found in the astronomy tables, well, at least in 2003 for FS9. For instance, if you were watching the first half at 00:00:00Z on the offical date the moon becomes full, as one expamle, you can watch it jump from half to full during your flight. By checking the tables and looking for a night moon (at my location, which is EST), I found it this one. I went to November 8, 2003 to see the moon change at 00:00:00Z. Also notice that the official change in the charts wawe 01:13Z for that particular month.
I used November as the month and year here at my time zone, because the change occurred during the night time hours. If you’re located in a different time zone simply use the local time charts to find a visible moon to watch the change in your part of the world. I used these charts provided on the USNO site which comes in handly for celestial nanagation as well.
For the moon phase changes go to the Phases of the Moon UTC charts. http://aa.usno.navy.mil/data/docs/MoonPhase.php
The moon’s rise and set charts for your local time zones are here. http://aa.usno.navy.mil/data/docs/RS_OneYear.php
Upon making some more more observations I see that the moon phases were correct until February 29, 2003 (leap year), before the phase differences began to show up. How much, is only determined by what figures MS used as a time constant for moon phase changes. For instance the change to a full moon was offical on March 6, 2004, but doesn't happen until March 8, 2004 in FS9. Once again, I'm using USA EST as my local time zone.
At this point in time in 2011, the phases are 10 days behind. Incidentally, I also found that the phases will be back in sync in the year 2025 in case you only fly real time and don't care or just want to wait.
I hope this helps
