Solar Flare Produces Coronal Rain 2012-07-19 NASA Goddard Solar Dynamics Observatory
In the first part of the video, the plasma is very bright in the visible temperature range. But as time passes, the plasma heats and becomes invisible.
In the latter part of the video, notice how plasma seems to appear at the top of the line of magnetic flux tubes. If there is a plasma circulation pattern in place, the upward leg of that circulation is now invisible in visible temperture range. Hot plasma is not usually invisible, as demonstrated by the downward lag of the circulation. That downward rain of matter seems to appear out of no where. This is due to the cooling of the plasma over time as its energy is radiated away.
Invisible plasma in visible light is iron at a temperature of about 1,000,000C as XUV of black body radiation. As the plasma cools, its temperature drops to 7,000C and glowing with intense visible black body light.
A quack fusion based reaction must be producing the energy necessary to elevate the plasma temperature of the highly ionized iron to over 1,000,000C. No conventional fusion reaction that I am aware of can transform hydogen directly into iron at the low fusion(hot) temperatures in place within this plasma circulation..
