atmospheric refraction

In addition the atmospheric refraction adds another 0.5 to that value.

"No, it's moved a greater distance than an atmospheric refraction would have in the same time."

Atmospheric refraction causes the Sun to be seen while it is still below the horizon.

The findings were dismissed by critics as the result of atmospheric refraction.

Such conditions may include ground relief, camera tilt and atmospheric refraction.

Related issues of atmospheric refraction applied to all astronomical observations.

Atmospheric refraction also makes the image of the Moon slightly smaller in the vertical direction.

For sunrise and sunset calculations, we assume 0.833 of atmospheric refraction.

"Far beyond it, if the atmospheric refraction is not taken into consideration," said Barbicane.

False readings can also be produced by atmospheric refraction of the Sun when it is close to the horizon.

Variations in atmospheric refraction can alter the time of sunrise by changing its apparent position.

He writes on the atmospheric refraction of light, for example, the cause of morning and evening twilight.

Neglecting atmospheric refraction, declination is always 0 at east and west points of the horizon.

Atmospheric refraction causes astronomical objects to appear higher in the sky than they are in reality.

Accounting for atmospheric refraction and measuring from the leading edge slightly increases the average duration of day relative to night.

Due to a normal atmospheric refraction, sunrise occurs shortly before the sun crosses above the horizon.

The formulas neglect the effect of atmospheric refraction.

The sunrise and sunset times reported in our calculator have been corrected for the approximate effects of atmospheric refraction.

(This estimation does not take account of atmospheric refraction.)

Ptolemy wrote on the atmospheric refraction of light in the context of astronomical observations.

It is also asserted that Brunel failed to account for atmospheric refraction and the effect is visible a few days too early.

Towering and stooping are more complex forms of atmospheric refraction than looming and sinking.

Clearing the lunar distance means correcting for the effects of parallax and atmospheric refraction on the observation.

Problems of atmospheric refraction were addressed by Vahe Gurzadyan in a 2003 publication.
