Is it possible to work out the date this was filmed?
One for the Astro experts

- Start date

You might be able to hazard a guess at the time of year and the approximate date, but not the year. The stars are in much the same place (well sort of) from one year to the next. There's a little precession of the earth on its axis, (wobble which mucks things up) and you might need a time as well, so that you can do some approx calculations backwards...

Thanks.I know it was filmed this winter.
Just an academic excercise really. I like the ships lights heading over the horizon.

I know you've now said it's this winter which is obviously a big clue! However just a little info that I used to try and work it out! I paused video at 0:05.
1) At this time I can just make out the constellation of Orion (directly above the isolated rock). It's hard to spot in all the clutter but Orions belt and dagger are definately visible. This makes it definately winter since Orion is not visible from Freshwater bay in the summer.
2) Theres a bright object top right of the frame. In January this year Jupiter was in about this position relative to Orion.
3) Another bright object (Sirius or Dog Star) is clearly visible between the isolated rock and the rock (or headland) on the left. The position of Sirius doesn't change relative to Orion so can't use it to find out time except that it rises at about 6:30 in Mid January and since it's not very high over the horizon I'd guess that it's about 8:30.
So final answer:20:30 Jan 15th 2012

Close!!!!!
It was actually the evening of 25th of January. Not sure of the exact time, as it was a long time lapse.
I will ask the film editor when he gets home.
