Mag storm
 

There was a pretty strong visible aurora in Central Ohio at 2-3am; at 5:30 the
AM band is wiped out, no WFAN 660 NYC in Central Ohio, not even any Cubans to
speak of. So N-S is wiped out too.

Yeah, SW is pretty quiet today.

Hang on though, it'll clear up once again.

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.

3-day Solar-Geophysical Forecast issued Nov 9 at 22:00 UTC

Solar Activity Forecast: Solar activity is expected to be moderate to
high. Region 696 is expected to produce M-class flares, and X-class
flares are possible.

Geophysical Activity Forecast: The geomagnetic field is expected to
be at unsettled to major storm conditions on 10-11 November. A CME
shock associated with the M8 flare observed today should arrive on 11
November. Activity should subside to quiet to active levels on 12
November.

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.

Yes, I simply provided that for reference.

SO here's the question. There's some kind of absorption completely eliminating WFAN
from Central Ohio, at a time when it's normally loud like a local.

But at 05:42-05:46 WFAN surfaces twice, in a ``fade in,'' to tolerable levels;
for the rest of the time it's completely gone.

What can cause a fade in? Fade out is usual, and from competing paths. But
a fade in has to be disappearance of absorption, which somehow has to coordinate
over a wide area.

If it's D-layer, it would have some pretty long relaxation time, it seems to me.

(before and after is pure noise, no signal)
