There was a pretty strong visible aurora in Central Ohio at 2-3am; at 5:30 the

WFAN faded back in strong at 5:43am faded out again and now is back at 5:45

the fading cycle seems to continue.

It was definitely flat gone from 5:30 till now though.

The reflecting layer is always there, so it must be high absorption. I wonder
if it's D-layer like daytime, or some other mechanism higher up.

No, that's from xrays. There aren't any at night.

This would be precipitation from ions, if it were to be D region, which
they wouldn't detect.
