An atmospheric optical phenomenon typically manifests as a subtle crimson or scarlet luminescence above the horizon. This impact can stem from varied sources, together with daylight scattering off airborne particles, significantly throughout dawn or sundown, or from intense mild air pollution reflecting off cloud cowl. For example, a vibrant dawn after an evening of heavy rain may exhibit a pronounced model of this impact.
Its significance lies in its potential to point particular atmospheric circumstances or the presence of considerable mild air pollution. Traditionally, observations of such phenomena have been interpreted as omens or indicators. Understanding the underlying causes supplies insights into climate patterns, air high quality, and the influence of synthetic lighting on the evening sky. Documenting these observations can contribute to environmental monitoring and astronomical analysis.
