Just as a reminder...
Merope 5 turns bright blue when you are at a certain position above Merope 5C.
Usually it's a dull boring purple.
In fact, the stripes disappear, and form into blobs making it look almost identical to the UA head.
I'm not talking a little bit blue here...it triples in brightness and is BRIGHT BLUE.
BLUE! LIKE A UA! I have never seen this in any other system before, and to me it is singularly THE most outstanding clue we have.
And yes, I will try and get a screenie. It has been independently verified by another commander.
I think this doesn't mean anything. There where changes about the brightness in the game. Are you flown in the last time to Obsidian Orbital? Right in the moment when you approach the light-reach of Maia A 2 the Nebula and background flashes really bright. Because of the Change of the light from the sort of star. The same happens when you approach on the surface of a planet.
Don't let us forget that Merope 5 isn't a planet, it's a dwarf-star. That means, here happen the same differences in brightness.
So i don't think that the colour-changing belongs to some mystery. [blah]
