We need UV from theSunto charge the ionosphere.
... so .,sun spots are cooler ... so darker .. so wave lenght is
lower .. so give out more uv than normal

that sound right ?

G .
Sounds right to me.
Not quite right. UV is a higher frequency than visible light and X-ray
are a higher frequency than UV.

Low to high frequency is infra red (radiated heat), visible light, UV,
X-rays.


I use good old "Roy G. Biv"* to remember it. (For those unfamiliar
with this mnemonic, "vide infra," -- pun intended.) So, we get...

infrared ("below" red) -- red (the "R" in Roy) -- other colors, in
order -- violet (the "V" in Biv) -- ultraviolet ("beyond" violet).

A little Latin and etymology goes a long way.

[* Roy G Biv == the order: Red, Orange, Yellow, Green, Blue, Indigo,
Violet.]


Which is also mostly follows the resistor color code.

0 black
1 brown
2 red
3 orange
4 yellow
5 green
6 blue
7 indigo (purple)
8 gray
9 white

Violet gives willingly.
