Abstract

Scientists at the Naval Research Laboratory (NRL) report what they say is the first positive evidence of a celestial body colliding with the sun. Recent analysis of data from NRL's SOLWIND experiment shows that on August 30, 1979, a comet apparently collided with the sun, scattering cometary debris in a halo that rose millions of kilometers above the solar surface.

SOLWIND, in earth orbit aboard the Department of Defense's P78-1 satellite, includes a coronograph designed to measure activity in the sun's outer corona. One of the instrument's features is an occulting disk, which simulates a total solar eclipse.
