Abstract
The Solar Eclipse Corona Imaging System (SECIS) was used to record high-cad ence observations of the solar corona during the total solar eclipse of 199 9 August 11. During the 2 min 23.5 s of totality, 6364 images were recorded simultaneously in each of the two channels: a white light channel, and the Fe xiv (5303 Angstrom) 'green line' channel (T similar to2 MK). Here we re port initial results from the SECIS experiment, including the discovery of a 6-s intensity oscillation in an active region coronal loop.
