For two hours in the morning of 20 April 1535, the skies over the city were filled with white circles and arcs crossing the sky, while additional suns (i.e., sun dogs) appeared around the Sun. Light pillar
Glory around the shadow of a plane. The position of the glory's centre shows that the observer was in front of the wings. A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds.
The 90° inclination between the ray entrance and exit faces produce the well-separated spectral colours. The arc has a considerable angular extent and thus, rarely is complete. When only fragments of a cirrus cloud are in the appropriate sky and sun position, they may appear to shine with spectral colours. [5]
22° solar halo with very thin cirrostratus clouds. In folklore, moon rings are said to warn of approaching storms. [7] Like other ice halos, 22° halos appear when the sky is covered by thin cirrus or cirrostratus clouds that often come a few days before a large storm front. [8]
True polar night is limited to latitudes above roughly 84° 34' North or South, which is exactly 18° within the polar circles, or approximately five and a half degrees from the poles. The only permanent settlement on Earth at these latitudes is the Amundsen–Scott scientific research station in Antarctica , whose winter personnel are ...
Earth's shadow cast onto the atmosphere can be viewed during the "civil" stage of twilight, assuming the sky is clear and the horizon is relatively unobstructed. The shadow's fringe appears as a dark bluish to purplish band that stretches over 180° of the horizon [3] [4] opposite the Sun, i.e. in the eastern sky at dusk and in the western sky ...
We don't quite remember the first time we had dark circles. And yet, one day, they took up residence underneath our eyes—uninvited, mind you—and just never left. Although there are several ...
Different coloured haloes have specific meanings: orange for monks, green for the Buddha and other more elevated beings, [12] and commonly figures have both a halo for the head, and another circular one for the body, the two often intersecting somewhere around the head or neck. Thin lines of gold often radiate outwards or inwards from the rim ...
