Scientific paper

Theoretical suggestions that there should be a ring of dust in near-ecliptic orbit about the sun have been supported by some past observations. It is reported here that a search for excess IR emission in the solar equatorial plane during the eclipse of July 11, 1991 failed to find any signature of dust evaporation. It is argued that the earlier observations were credible, and that the circumsolar dust ring is a transient feature, perhaps due to the injection of dust into near-solar space by a sun-grazing comet.
