Record 1 2024-04-05

English

Subject field(s)
  • The Sun (Astronomy)
DEF

[The] outermost region of the Sun's atmosphere ...

OBS

It has a temperature of approximately two million kelvins and an extremely low density. The corona continually varies in size and shape as it is affected by the Sun's magnetic field. ... The corona shines only about half as brightly as the Moon and is normally not visible to the unaided eye, because its light is overwhelmed by the brilliance of the solar surface. During a total solar eclipse, however, the Moon blocks out the light from the photosphere, permitting naked-eye observations of the corona.

English

Subject field(s)
  • Atmospheric Physics
DEF

Name given to the parhelia, paranthelia or the anthelion when they are particularly bright.

CONT

A halo occurs when the light from the sun or the moon is refracted and reflected by ice crystals in the atmosphere ... Under certain circumstances a second, or outer, halo appears, which is fainter than the inner one. At times white or colored luminous arcs are also seen lying somewhat parallel to the horizon and passing through the source of light, called mock suns, parhelia, or sun dogs for the sun, and paraselenae for the moon. A single mock sun, the anthelion, directly opposite the sun, may be added.

CONT

A sundog is a brightly colored spot that appears to the right or left of the sun. Sundogs form when the sun is near the horizon and the sunlight is refracted (bent) by hexagonal, plate-like ice crystals floating horizontally in the air. Sundogs are brightest in winter because ice crystals are more common, but can be seen at any time. Sundogs are also known as mock suns or parhelia.

Record 6 1977-09-26

English

Subject field(s)
  • Astrochemistry and Cosmochemistry
  • Astronomy
OBS

The only parts of the sun that can be observed directly are its outer layers, collectively known as the sun's "atmosphere". The solar atmosphere is not stratified into physically distinct layers with sharp boundaries. Yet there are three general regions, each having substantially different properties, even though there is a gradual transition from one region to the next. These are the "photosphere", the "chromosphere", and the "corona".
