Auroras have no definite size. They occur when charged particles from the Sun ionize particles in the upper atmosphere as they spiral in toward Earth's magnetic field. Auroras may be localized in one area, or may extend from horizon to horizon in the sky.
Auroras occur in the mesospere.
Auroras appears in the night sky by atoms and molecules. Auroras is lights in the sky.
The Auroras of Autumn was created in 1950-09.
auroras are the northern lights, and that is a very important event in Alaska
Sun dogs are formed differently to auroras
Which can cause auroras and disrupt satellite transmission?
Auroras are produced by interactions among thermospheric gases and free electrons

No. Auroras are caused by streams of charged particles from the Sun, fired at the Earth by a coronal mass ejection; a massive solar flare. The charged particles interact with the Earth's magnetic field in the upper atmosphere and cause a glow. God's Own Neon Signs in the sky, you might think of it. Auroras are typically seen only at fairly high latitudes in the winter (because at high latitudes in the summer, the sky is too bright for auroras to be visible). However, a really big CME can cause auroras down to mid-latitudes, and in one extreme case, lit up the skies of Miami, Florida!
Magnetic storms unleashed by solar flares can cause auroras, but all solar flares don't cause auroras.
is it false that auroras are the result of energy from solar flares
