A total shadow, especially that cast on the earth by the moon during a solar eclipse Those areas of the earth experiencing the umbra will experience a Total Solar Eclipse
During an eclipse the part of the moon's or earth's shadow in which the solar disk is completely hidden Also refers to the inner region of a sunspot
Dark central region of a sunspot In an eclipse it is the dark central part of the shadow cast by an illuminated body
cirrhosa, which is highly esteemed as a market fish; called also ombre, and umbrine
The conical shadow projected from a planet or satellite, on the side opposite to the sun, within which a spectator could see no portion of the sun's disk; used in contradistinction from penumbra
{i} shade, shadow; area of the shadow of an eclipse, dark center of a sunspot; spectral image
1: area of total shadow, especially during solar eclipse 2: cool and dark central region of a sunspot, with a strong vertical magnetic field
The darkest part of the shadow cast by an astronomical object The umbra of a solar eclipse is the region wherein the eclipse is total The penumbra surrounds the umbra, and is the region which sees a partial eclipse
The darker core of a shadow, usually cone shaped, and surrounded by a lighter penumbral shadow Also refers to the darker center of sunspots (Back To Top) W
a complete shadow (as of the Moon) within which the source of light (the Sun) is totally hidden from view V W
umbra = [Latin] shadow The umbra is the centermost, darkest part of a sunspot It can get over 12,000 miles (20,000 km) in diameter, though most umbrae are at most about half that size The magnetic field in umbrae is strong: from 1500 up to about 3000 G Umbrae are darker than their surroundings because they are cooler Most of the visible solar surface has an average temperature of some 5700 K (10,200 degrees F, 5400 degrees C), but the visible parts of big umbrae have temperatures of only about 3700 K (6600 degrees F, 3400 degrees C) A big umbra can be seen in the high-resolution continuum image
