Sun Dogs at the Very Large Array
Sun Dogs at the Very Large Array

November, 1986

On the Plains of San Agustin in western New Mexico, the
National Radio Astronomy Observatory operates the Very Large
Array, one of the world's foremost radio telescopes.

Twenty-seven 25-meter diameter dishes comprise the antenna
array. The dishes shown here are along one of three 13-mile-
long legs that form the Y-shaped array. These immense dishes
are moved to various positions along the railroad tracks in
the foreground.

During this visit on an afternoon with thin, high clouds,
I witnessed the most impressive display of atmospheric halos
I have ever seen. Visible in this photo are two "sun dogs,"
or parhelia, like miniature rainbows on either side of the
sun. A brilliant "sun pillar" seems to extend upward and
downward from the sun itself. These were only part of an
incredibly complex pattern of arcs and rings that covered
half the sky -- a "very large array" indeed!
