Interferometry applied to Visible Solar Features
Abstract
THE study of the solar atmosphere at visible wavelengths has clearly shown that it is inhomogeneous, with a small scale structure, and that interpretation of observational results in terms of simple homogeneous models can give misleading or even completely spurious results. The best resolution that has been obtained in visible light solar observations is of the order of 1/3 arc s, equivalent to 240 km at the solar distance, and many solar features are unresolved even on this scale. Prospects for a significant improvement in the resolution obtainable with instruments on the Earth are poor because of the presence of the Earth's atmosphere.
