St. Elmo’s Fire can appear as a glow on a masthead that’s produced by an extreme buildup of electrical charge like during Idalia. The light we see is the result of air molecules tearing apart.

Pilots evacuating in preparation for Hurricane Idalia observed bright blue light outside their aircraft, an event called St. Elmo’s fire. Here’s what causes it.

However, lightning and St. Elmo's fire are different. "Lightning is a direct movement of electrons from a cloud to the ground," he said, "while St. Elmo's fire is like a sparking effect, where ...

St. Elmo's Fire occurs when the atmosphere becomes charged and an electrical discharge of plasma is created between an object and the air around it. This can happen to aircraft flying through ...

ST. Elmo's Fire as seen occasionally at the Ben Nevis Observatory takes the form of jets of light on the tops of all objects that stand any height above the general level of the roof of the ...
