Northern Lights here tonight

[Bill, KD0HG]

Went out for a walk wiith Chester the Great Pyrenees on a beautiful late summer evening around 10 PM local, there was quite a pronounced blueish band of aurora low on the northern horizon from about 330 to 30 degrees azimuth without much elevation to it. It faded out about a half hour later.
I really need to get my VHF act together and get some 6M and 2M yagis up someday.

Explains the bands!

75 meters is dead, few local signals, some form the mid area, but no long distance at all.

It's no wonder.  Band conditions on 75Mtrs this morning were quite bad!  Some signals were still coming through but were down some 20-40 db from usual.

My experience last night on the bottom of 80 was that 300W from a pair of 811's didn't produce squat even after about 15 minutes of cqing.  Later I listeed on the bottom of 40 before bed using a cheap bedside SW with BFO and heard plently of activity.  80M was dead.  I did hear some guys in NE fb on AM but not as strong as usual.

Probably because the D-layer got all energized which enhances D-layer adsorption on the lower frequencies (i.e. 75 meters late mornings and early afternoons on most days). As you go higher in frequency, the D-layer adsorption is less effective. Normally, under “average” conditions, the D-layer disappears, or is less effective, during the evening hours. When you have high sun activity like this, the D-layer becomes a giant RF sponge

That "Darn D Layer". 
20 meters is booming, some sort of "corntest", but the low bands are dead, can just hear CHU.

6 meters has been hot all weekend, cause it's "VHF contest weekend". No aurora activity to speak of. Lots of scatter between 12 & 3 AM Sunday morning, but that's normal.

Pete,

Your avatar is trippy, I think I feel a seizure coming on.

You should watch it after several beers for the real effect.

I'd rather watch it after some Mr. Natural  (Yo dude! I'm gettin a Dell!)

Beautiful blue sky tonight on the way home from the beach. A bit of glow but no light show.
