Changes in Earth's magnetic fields. As I understand it, the A Index
is a 24-hour average. Now, how do you use it? Well, speaking in
*general* terms (hold on here, I have to put on my asbestos skivvies),
an A index of less than 15 and a K index under 3 is going to yield good
HF (Shortwave) propagation. You'll also hear talk of solar flux.
Solar flux is a measurement of microwave radiation from the sun, and
*generally* can be used for predicting HF propagation - *if* you use
a smoothed average number.

I have a couple of really good links to share, if you found any of this
interesting.
