Yeah my husband and I saw that a few months ago. It ended up being a planet and the colours were light refraction or something. That was the explanation I was given and when I posted there were a lot of people who had seen exactly the same thing.

Lots of different ideas on what it was of course.

Strange that we are starting to see these flashing colours off stars when we haven't before.

Collapsing heliosphere?

Collapsing magnetic field?

I am a pleb and not very good at getting my head around this celestial stuff. It must be some sort of atmospheric interaction though.

Perhaps its all inclusive with Sickscent's fluff. Probably is.
