occulting

She was seeing the Sun's tenuous atmosphere, made visible by the artificial occulting of the central star.

In 1944 the clockwork mechanism controlling the occulting of the light was replaced, as the original was considered on the verge of failure.

In other words, the plane through the Earth's center perpendicular to the shadow axis, which is the line through the centers of the occulting and the occulted body.

In Britain, the Whidbey Automatic Light (Occulting Green) was constructed at the eastern end of Plymouth Sound in 1980.

The Big Occulting Steerable Satellite (BOSS) was a proposed satellite that would work in conjunction with a telescope to detect planets around distant stars.

A comparable proposal was also made for a satellite to occult bright X-ray sources, called an 'X-ray Occulting Steerable Satellite' or XOSS.
