Abstract

The Williams College expedition to Râmnicu Vâlcea, Romania, made observations of the solar corona (a) to compare with the Extreme ultraviolet Imaging Telescope (EIT) on the Solar and Heliospheric Observatory; (b) to search for the source of coronal heating through a study of the oscillatory power spectrum of coronal loops in an emission line typical of high temperature; (c) mapped the coronal temperature using ultraviolet continuum observations; (d) made videos and still photographs of coronal motions and details; and (e) collaborated with the scientists at the Astronomical Institute in Bucharest.
