In summary, a new satellite, the Taiwanese Rocsat-2, has been studying the high-altitude phenomena of sprites, jets, and elves - strange flashes of colored light in the Earth's upper atmosphere. These phenomena are believed to be discharges of electricity from above thunderstorms and are part of a global electrical circuit. However, it is unlikely that these phenomena are responsible for a circular rainbow seen in Granada, Spain, at 4:00 PM with no clouds in the sky and at a distance from the sun. The cause of this specific rainbow remains unknown.

I once say a circular rainbow the diameter of the sun, is this the result of this phenonmena?

Probably not. Were you in an airplane at the time?

No I was on land, Granada Spain, at 4:00PM no clouds in the sky and the rainbow was a good distance from the sun about a 45 degree angle off horizon. Water vapor in a concentrated are, maybe a comet burnout in high atmosphre. The country is notorious for sky phenonema, you know we have large chucks of ice fall from the sky, that has no explanation either.
Related to Fresh data on sprites, jets and elves
What are sprites, jets, and elves?
Sprites, jets, and elves are all types of transient luminous events (TLEs) that occur in the upper atmosphere, above thunderstorms. They are often described as lightning bolts that shoot upwards instead of downwards.
How are sprites, jets, and elves formed?
Sprites, jets, and elves are formed when a strong electrical discharge from a thunderstorm interacts with the upper atmosphere. This causes the gas molecules in the upper atmosphere to become excited and emit light, creating the unique shapes and colors of TLEs.
What is the significance of fresh data on sprites, jets, and elves?
Fresh data on sprites, jets, and elves helps scientists better understand the mechanisms behind these phenomena and their connection to thunderstorms. This can also lead to advancements in weather forecasting and space weather research.
How is data on sprites, jets, and elves collected?
Data on sprites, jets, and elves can be collected through various methods, including ground-based cameras, satellite observations, and high-altitude aircraft. Each method has its own advantages and limitations, so a combination of data sources is often used for a more comprehensive understanding.
What can we learn from studying sprites, jets, and elves?
Studying sprites, jets, and elves can provide insight into the electrical processes that occur in the upper atmosphere and how they are affected by thunderstorms. This can also help us understand the Earth's global electric circuit and its impact on the Earth's climate and space environment.
