Hi,

Because I have no idea but routinely listen to HF aeronautical worldwide, what constitutes a good K index and a good A index if 5 and 63 are terrible?

Also, is this regional or worldwide?

An finally, where can I find K and A indexes so that I can monitor them daily?

I appreciate all or any responses as I broaden my knowledge from those that know better!

Cheers,

Michael,
Here is a basic explanation...

K index of 1 or 2 is good, 3 is fair and 4 and above is bad.

BTW, K index is current, A index is the (24 hr?) average, and these are
worldwide.

You can find these figures at these two sites:

dx.qsl.net and then choose "Propagation" at the main screen.

spaceweather.com these figures are on the left side of the screen;
scroll down to them for the current figures and click on "explanation"
