Hi... Apologies if this is in the wrong section but it is kind of homework related.

I'm looking at an ultraviolet image of the sun... Would I be right in saying that brighter areas represent higher temperatures and darker regions represent lower teperatures?

Brighter simply means more photons per unit area (intensity), i.e. more recombination reactions, so that doesn't necessarily imply higher temperature, but it could. The reaction rate is related to temperature as well as particle density.

Darker usually implies cooler.
 
Is it possible to view things in the UV with goggles or scopes?
