Just wondered if the VHF frequencies get affected same as HF during the
solar flareups?

In general, HF reception becomes very poor while VHF can be enhanced.
This is why the amateur radio people like to do 2-meter (VHF) DX'ing
during a geomagnetic storm with an aurora.

Last night (Thursday) I was receiving VHF aero comms on 128 - 134 MHz from
about 200 miles out here on Long Island, NY.

That's normal. How about ground based stuff?

6 was supposed to be open a bit last night, all I heard when I checked was
a beacon, K2ZD/B. I heard it from the Hudson Valley of N.Y.

It finally opened up half decent here last night. "Houston". Heard a
few Hawaii stations. Quite a few stateside also. But the long haul
stuff seemed to be doing the best. The KH6's were blasting thru fairly
well. MK

Thats normal if they are in the air. I hear 200-300 miles away
consistantly. Same with the VHF ACARS transmissions. MK

Hawaiians were reported strong on 50MHz as close to me as Memphis -
unfortunately I was at work at the time!

Channel 2 TV from Honolulu was definitely logged in Vancouver. There is
evidence to suggest the same station was seen in Shreveport and the
Lower Rio Grande Valley in extreme south Texas.

Propagation characteristics almost seem like a cross between Es and F2.

Dang...Didn't even think to look at the tv...It's kind of a hassle, as
I have to unhook the cable, etc...The KH6's seemed pretty F layerish.
Real steady for long periods of time. Almost like 10m. Some of the
stateside stuff might have been e layer. MK

See, I *knew* there was a good reason I don't have cablegrin!

The Vancouver DXer was certain the opening was double-hop Es.

The E and F layers are both ionized layers of the upper atmosphere that
refrace radio signals. It's already accepted that a F1 layer merges
with F2 at certain times - my question is whether maybe both F layers
merge, at least partially, with the E layer on rare occasions. The
immense magnetic storm we've experienced would certainly seem capable of
triggering unusual effects.

The Texas and Louisiana reporters did feel the signals had F-layer
characteristics - severe multipath (much easier to detect with TV
signals than with SSB!) and a relatively stable MUF within the TV channel.

Given the difference in locations and latitudes, I suppose it's possible
there was double-hop Es and F2 at the same time!
