AB: Global temperature and wind speed of free electrons in the solar corona can be measured using light from the visible portion of the electromagnetic spectrum. Davila et al (SH06, Fall 2007 AGU) describe the results of a spectrometric investigation using this technique. In this report we describe a second technique based on filtergrams, which permit the entire inner corona to be imaged using ratios of individual exposures. The data gathered during the total eclipse in Libya March 29, 2006 has provided an opportunity to make such a measurement. Preparation of the data as well as calibration of the instrument played a critical role in eliminating uncertainty and obtaining useful results. In this presentation we will discuss the details of this preparation and present preliminary results.
