If clouds are water vapor, a gas....

Still nothing explains why they did not move, nor change shape in over an hour..?
HAARP frequencies + nano particles in the atmosphere...
The clouds are intended to simulate naturally-occurring phenomena called noctilucent clouds, which are the highest clouds in the atmosphere.
“This is really essentially at the boundary of space,” said Wayne Scales, a scientist at Virginia Tech who will use computer models to study the physics of the artificial dust cloud as it’s released. “Nothing like this has been done before and that’s why everybody’s really excited about it.”
The noctilucent or "night-shining" clouds are at an altitude of 47 to 53 miles (76 to 85 km), where meteors and bright aurora lights are not uncommon and the atmosphere gives way to the blackness of space. The clouds remain a scientifically baffling phenomenon more than 120 years after their discovery.
At heights of 80 km (50 miles), the gas is so thin that free electrons can exist for short periods of time before they are captured by a nearby positive ion. The existence of charged particles at this altitude and above, signals the beginning of the ionosphere a region having the properties of a gas and of a plasma. The ionosphere is indicated by the light green shading in the figure to the left.
They are normally too faint to be seen, and are visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth's shadow.
....most often observed in altocumulus, cirrocumulus and lenticular clouds, and very rarely in Cirrus clouds.
Iridescent clouds are a diffraction phenomenon cause by small water droplets or small ice crystals individually scattering light.
Latitude is the key. The sun must be higher than 58° to form the arc. The further from the equator the less time that the sun is sufficiently high.
