In February last year, HAARP unexpectedly managed to induce a strange bullseye pattern in the night sky.
Observations of HF-induced artificial optical emissions at the 3.6 MW HAARP facility show unexpected features not seen at the previous 960 kW level. Optical emissions often form a bright rayed ring near the 10% power contour surrounding a central disk with a sharp edge near the 50% power contour.
We conclude that the optical bullseye patterns are a refraction phenomenon and an indicator of ionization production within the transmitter beam.
If the spiral were 2-3 times the size of the full moon that would make it 1.5º across, the width of the tip of your thumb held an an arms length. Obviously, in some of the images it appears much, much larger than that. In the others, it seems about right.
But a little more research found this. A visible disk with an outer ring is produced.

No.
That calculator is asking for radians. Not degrees.
radians = degrees * pi/180
1º = .01745 radian
tan(1º)=.01745
Coincidence? Not really.
tan(.0175)*500=8.75

One radian is the angle of an arc created by wrapping the radius of a circle around its circumference.

What's ludicrous is to believe that a circle with a 1º angular diameter would have a larger diameter than the distance from it.
Think about it. 500km away? 546km diameter?
One radian is the angle of an arc created by wrapping the radius of a circle around its circumference.
To convert radians to degrees:
radians = degrees * pi/180
(Here's just one place you can look it up. There are gazillions of others)
Solving for radians:
z = 1º x pi/180
z = pi/180
z = .017453
Solving for diameter:
diameter = z * 500
diameter = 8.727
You can also look up the tangent of 1º here
So now lets use degrees instead of radians.
tan(1º)=.0175 (from the table, it's rounded up a bit)
500 x .0175 = 8.75
You are wrong.

Shouldn't the shutter speed able to be (roughly) calculated? I don't have the inclination but perhaps you could use rotation speed of the rocket (from a video) and the arc(s) from the exhaust of the rocket in the long exposure photo.
If, as you say, the spirals are exactly overlapping each other in that photo, then the exposure should be the time it takes the rocket to rotate 180 degrees.
Originally posted by GobbledokTChipeater...obviously the shutter speed is slow, but if it was as slow as you are making it out to be then shouldn't the picture just be a single gray disc?

Yet you don't respond to some of the more "intelligent" questions. Like how can the effects of a rocket, which was fired 800 Km's away, in a different direction to the observer be seen?

I'm not an expert in photography but have dabbled in it. See if this makes any sense, the foreshortening effect caused by telephoto lenses.
When using a long lens the space between objects appears to shrink, the objects get jammed together, the more distant object appearing too close to the nearer one. Doesn't this occur because the angular size of the more distant object is increased more than the angular size of the closer object? Because the more distant object is "enlarged" more (relative to the nearer object) it appears to be closer to the nearer object than it actually is. The longer the lens, the more pronounced the effect.
In a similar way, some of the photos make the spiral appear closer to the foreground (larger) than it was, while in other photos, made with a wider angle lens it appears much smaller.
