A sudden and brief burst of light observed in the sky is commonly referred to as a "flash of light." However, the specific terminology used may vary depending on the context and the cause of the phenomenon. Here are a few terms that might be used to describe different types of flashes of light in the sky:
Lightning: This refers to the visible discharge of electricity between the atmosphere and the ground or between different areas of the atmosphere. Lightning is often accompanied by a bright flash of light.
Meteor or Shooting Star: When a small celestial object, such as a meteoroid or space debris, enters the Earth's atmosphere and vaporizes due to the heat generated by atmospheric friction, it creates a bright streak of light. This is commonly known as a meteor or shooting star.
Fireball: A fireball is an exceptionally bright meteor that produces an intense flash of light as it enters the Earth's atmosphere. Fireballs are typically larger and brighter than regular meteors.
Flashes of Light from Atmospheric Phenomena: There are various atmospheric phenomena, such as certain types of lightning, ball lightning, or electrical discharges in storm clouds, which can produce unusual flashes of light in the sky.
It's important to note that the terminology used can sometimes overlap or vary depending on the specific scientific or popular usage. Additionally, specific phenomena may have their own unique names.
