Yes: The sun isn't *ONE* temperature!
I "NEVER* claimed that it is! The ~ part of ~5700K means approximate. In this case it is an characteristic temperature derived from the roughly black body spectrum of the Sun. Any body that has a roughly black body spectrum is (roughly) at a temperature that emits that spectrum.
BUt the Sun *HAS* a spectrum that is roughly a a "black body". That means that it has a characteristic temperture of ~5700K.
Those MILLION DEGREE LOOPS act *NOTHING* like a 'black body' from a 5700K surface because they are NOT A BLACK BODY! They do *NOT* have the spectra of BLACK BODIES "as far as I know".
I do not know. Why dont you tell me..
As I openly and honestly stated, Bruce's theory is obviously flawed:
- There is no dust at the temperature of the Sun. FYI, MM this is ~5700K.
Even sunspots have a temperature of ~3100K.
- There is no dielectric medium to breakdown and allow electrical discharges.
- Electrical discharges emit narrow band X-rays that have never been observed from the Sun.
- Also: 50 years of observing the Sun has never detected the dust. IN fact no solids at all have ever been observed on the Sun.
The observed temperture of the Sun does matter because it rules out Bruce's theory.
It is even worse -
solar flares and prominences happen above the photosphere where the temperature is higher.
ETA
Just to emphasis this: His theory is that solar prominences are essentially lightning caused by charges building up in dust in the solar atmosphere. Prominences are not restricted to sunspots. They happen all over the solar surface. So the temperature of the entire solar surface is a factor. That temperature is ~5700K which rules out dust.
But the real killer for his theory is the point that you have not addressed Michael Mozina:
There is no dielectric medium to breakdown and allow electrical discharges. That is a basic requirement for an electrical discharge or lightning.
And I will add another flaw:
- Let us say that there is dust within the plasma of the Sun's atmosphere.
What happens to any charge that this hypothetical dust acquires when it rubs together in a conducting plasma?
The answer is that the charge goes away! The mobile electrons and ions in the plasma neutralize it.
So Bruce's theory requires that the Sun have no plasma

!
No - I have simplified to process to cater for your level of knowledge of physics. I know that the Sun has various temperatures, the ~13 million K in the core, the ~5700K average of the photosphere, the ~3100K of sunspots, millions of K in the corona, etc.
Why cite Alfven? It is almost as if you have never read any modern textbook on solar physics

!
The plasma above the photosphere is measured to have MIXED TEMPERATURES. And as you stated - *HIGHER* in filaments.
That is correct: At ~3100K, carbon can became a *SOLID* . So what?
Flares (Bruce's lightning and your electricsl discharges) are not exclusive to sunspots.
Carbon and Neon form
plasmas when their degree of ionization is significant (~1% or better).
