As the owner of a Newtonian reflector, an avid user of
http://www.stellarium.org/ software, a very well trained navigator by both day and night and also navigation whilst thousands of feet in the air, I am very well aware of what #should# be where and why the mechanics, physics and mathematics say it should be there.
However, I am not talking about a constant change (although the sun is much brighter, painfully so on a permanent basis) I am talking about possible mistakes in the holographic sky, or what ever is going on up there.
I once watched a star form in the sky over head whilst high over the Uk, change a few colours and then blink off again.
Some thing is not right in the skies, and I don't think its some thing we are going to be able to figure out in the near future; just keeping tabs and making sure each other witnesses know they are not 'seeing things' or going 'crazy'.
