What is the term used for the glow of light often seen beyond the horizon?

The term "LOOM" is used to describe the phenomenon of light appearing beyond the horizon, often associated with atmospheric conditions that can cause distant objects, such as land or ships, to appear elevated or visible. This effect can occur due to refraction, which bends light rays, allowing them to be seen even when they are technically below the horizon line. The phenomenon can create a dramatic visual appearance, making it particularly important for navigation and safety at sea, as it can affect how mariners perceive distances and landmarks.

In contrast, the other terms do not accurately capture the specific atmospheric phenomenon described. "Flicker" typically refers to a quick, brief light, while "glimmer" implies a weak or intermittent light. "Radiance" suggests brightness but doesn't specifically denote the atmospheric effect beyond the horizon. Understanding this terminology is crucial for those navigating maritime environments, as it helps in recognizing visual cues that may affect navigation and decision-making.
