No, the lights occur high up in the ionosphere, more than 60 miles (90 km) above the surface of the earth.

The region of the atmosphere located from 53 to 370 miles altitude is called the ionosphere. This space is ionized by solar radiation, which makes it incredibly helpful to mankind. Because of the ionosphere we are able to form radio propagation all over the earth as well as make consistent advances in geophysics.
ionosphere
the ionosphere is important is the it is in the thermosphere
The ionosphere is a layer of earths atmosphere. It is charged with a high concentration of ions. It is above the mesosphere about 50 t0 600 miles above the earth.
No, the lights occur high up in the ionosphere, more than 60 miles (90 km) above the surface of the earth.
Some are and some are not. If you hear an AM radio station at night from more than a few hundred miles away, or a "short-wave" station from maybe 100 miles away, chances are very good that it has reflected from the ionosphere before it reached you. It's very rare for TV or FM radio to reflect from the ionosphere. That almost never happens except during periods of high solar activity.
Any Amplitude Modulated radio signal will penetrate the ionosphere if its carrier frequency is high enough. Signals in the commercial AM broadcast band, with frequencies between 530 and 1700 KHz, aren't high enough. Most of their energy reflects from the ionosphere.

No, the lowest they come is about 60 miles (100 km) up in the ionosphere.
5 Miles high
The ionosphere is the part of the earth's atmosphere extending from about 30 miles (50 Kilometers) to the exosphere that contains ionized atmospheric gases. it influences radio propagation to distant places on the Earth.
The Ionosphere
The Ionosphere.
Explosions of high yield bombs in the ionosphere above the target. The effects can reach for a radius of a couple thousand miles around ground zero.
It is the ionosphere, a general region that includes all of the thermosphere and parts of the two bordering layers. In this region, between 60 and 1000 kilometers above the Earth, ionized particles refract and reflect radio waves back toward the ground. This enables radio transmissions that are normally "line of sight" only to reach over the horizon for hundreds or thousands of miles. This includes broadcast radio (HF) and shortwave bands.
