A narrow-band images taken in so called red and green coronal lines are presented on this page. The six-member expedition of the Slovak Academy of Sciences led by Július Sýkora observed the eclipse in Bratsk. The observing conditions were bad - the Sun was covered by cirrus clouds. While the white-light images of the solar corona were strongly deteriorated, the narrow-band images were surprisingly of excellent quality. After 26 years, the modern image processing methods enabled to take full advantage of these unique images.
