im really curious to learn if moon spins 180º as 12 hours pass by as all constellations do(at least at 45ºN)

stellarium doesn show moon phases but this game does

so what tweak can i make to see the 3/4 moon with a 12 hours difference with the game

mon rises on the east and hides on the west correct

but on moscow at least, every 12 hours every celestial body spins 180º

in the 7 hour difference moon doesnt spin a degree

i dont mind if matrix is wrong but i want the game to be accurate

Even though I'm an amateur astronomer, I haven't paid much attention to the representation of celestial bodies in this sim. (I have proper software for that! http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif)

But it seems that the Moon's always at the same gibbous phase, and probably fixed in the sky with respect to the Sun (as it should be if it stays always at the same phase.)

Not sure what you mean when you use the term "spin". The Moon is tidally locked so that its rotation period is the same is as its period of revolution around the Earth. In other words, it keeps the same face towards us.

I'll have to check to see if the Sun/Moon/stars all track across the sky at the same rate (due to the Earth's rotation on its axis.)

ill be more clear you are at 45ºN

a costellation like this: M rises on the east

when it hides on the west it should look like this: W

the same for the moon if it rises like a C on the east should hide like a D on the west

first i wonder if this happens in reality as it should or my teacher when i was 6 was right and the moon is the sun disguised

2nd i think moon is not correctly modeled as it raises as a C on the east and hides as C as well on the west and not as a D as it should

I remember reading somewhere (on the web) about research someone did into the game (IL2) with regards to celestial navigation. If I remember correctly he said the stars where fixed (the same) for every map at every time...They did not move across the sky...

If I can remember where I read it I will post the link...

I do look at the stars, and wonder in this sim, ut I spend alot of time over 30,000 feet though too in this sim.

Well, the clouds dont move, so no surprise the stars dont move either

i didnt sleep yesterday till i found out:

at 45ºN moon rises as a C pointing 45º up, in the zenith is a perfect C and when it hides is a C pointing 45º down so the moon is probably real

but consider in bob celestial dome revolves and you are in the N pole to simplify

ursa minor is at an altitude of 90º and it spins 90º each 6 hours

virgo at altitude 0º on the contrary will always keep same position it wont spin, it will look like moving along the horizont always in the same position without spinning

then perseo that is at 45º altitude will spin or not?

a cookie for whom he figures this out

actually in the game time doesnt pass by

then how planes move if time is still?

well maybe if time goes really slow and you very fast and time accelarates you could be playing for ever on a second of the il2 time

Hang on let me see if I get this, it's linked to your other moon thread right?
The one where you say the 'real' moon does look as you think it should. So what you want is for the moon in the game to appear as you think it should, not how the 'real' one does, is that right?

incorrect moon behaves as it should, the real one

but the fact it spins or not is relative

Raaaaaid. point your velocity vector at the moon.. and fly straight at it for 24 hours.

record a track and get back to me

i was questioning wether the moon is real or not, if is not real is perfectly modelled contrary to the game one

in the north pole a constellation at an altitude of 90º will spin but one at 0º will not

i cant figure out what about one at 45º

seems that 6dof specially spin is intimitaly related with perception and the concept of space

Just had to chip in with this thread - never mind the inconsistencies with the moon, has anyone, through all their flights over Russia, Europe, etc, ever seen one single, solitary SHEEP!?? Where did they all get to, I wonder,maybe they were gathered in some secret Stalag base, for sadistic, gene-transmuting experiments?

i studied navigation, all pilots have to study navigation, the most important part of navigation is astronomy

if you like piloting you must like stars like i do, nobody else to discuss stars?

or is it that what people enjoy of this game is shooting down people and dont give a dam about the stars

i guess is the second no wonder no girls around here they are nicer

Raaaid,

I'm an amateur astronomer who also understands the fundamentals of celestial navigation. I'm surprised at your question(s) here, given that you claim to have studied navigation. A part of the syllabus of a course in celestial navigation would be a study of the apparent movement and orientation of the celestial sphere.

If nothing else, do this. Download any free sky charting program (there's lots), or use an on-line utility which will do the same. Set the view to the horizon reference frame, which is how you (or myself, at least http://forums.ubi.com/images/smilies/16x16_smiley-wink.gif ) see the vault of the sky. Look east and note the orientation of a constellation which has just risen. Advance the time by about 10-ish hours (not 12, as the constellation will have set), face west, and note the constellation's orientation.

It WILL NOT be rotated by 180 degrees for mid-northern latitudes, but instead it will have rotated about 90 degrees (for those who live near the equator, it will have rotated about 180 degrees.)

Now, for us mid-northerners (and I mustn't forget our mid-southern folks), a circumpolar constellation (one which is close enough to Polaris as to never set) will be seen to do a complete rotation through 360 degrees as it circles round the pole.

==================

Going from just an impression of a memory here, but I think that in IL-2 the Moon's face is always oriented the same way with respect to the horizon. In other words, it will never be seen to rotate as it tracks across the sky, which is of course wrong. If this is the case, I'm sure it was assumed by the programmers that virtually no one would notice. Moreover, it adds what might justifiably be called needless programming complexity for such a trivial component of the scenery.

But I'm sufficiently intrigued to look into this with a more critical eye...

yes but spin is relative, if you are in the north pole seeing ursa minor it will certainly roatates

but a constellation at the hoizont for example leo will always lok at the right so it doesnt rotate

so that you see celestial body rotating or not depends on wether you take as a reference a point in the sky or the horizont

also in the equator ecuatorial constellations wont seem to rotate but just to rise vertically and as they are behind you as you changed position they look now upside down

btw i didnt pass navigation
