Discussion Overview
The discussion centers around recent data on atmospheric phenomena known as sprites, jets, and elves, which are flashes of colored light occurring in the Earth's upper atmosphere. The context includes the study of these phenomena by the Taiwanese Rocsat-2 spacecraft, which is exploring their potential connection to electrical discharges from thunderstorms.
Discussion Character
- Exploratory
- Conceptual clarification
Main Points Raised
- Some participants discuss the nature of sprites, jets, and elves as electrical discharges associated with thunderstorms, suggesting a connection to a global electrical circuit.
- One participant shares an observation of a circular rainbow and questions whether it is related to the phenomena being discussed.
- Another participant responds to the rainbow observation by questioning the conditions under which it was seen, specifically asking if it was viewed from an airplane.
- The original observer clarifies that they were on land in Granada, Spain, and describes the conditions during the sighting, including the absence of clouds and the angle of the rainbow relative to the sun.
- The observer speculates about possible explanations for the circular rainbow, including concentrated water vapor or a comet burnout, and mentions other unexplained sky phenomena in the region.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the relationship between the observed circular rainbow and the atmospheric phenomena of sprites, jets, and elves. Multiple viewpoints and hypotheses are presented without resolution.
Contextual Notes
The discussion includes speculative elements regarding the causes of the circular rainbow and references to other unexplained atmospheric events, indicating a need for further investigation into these phenomena.

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.
