Eclipse observed

12 April 2006

The UCL Mullard Space Science Laboratory has unveiled footage, taken in Libya, of the total eclipse that occurred on 29 March.

Dr Ken Phillips (UCL Space & Climate Physics), along with Pawel Rudawy and Adam Buczylko, from the Astronomical Institute at the University of Wroclaw in Poland, used the Solar Eclipse Coronal Imaging System (SECIS) to take images of the sun's outer atmosphere during the eclipse at 20 frames per second. The objective of the research is to find out why the sun's atmosphere, at up to two million degrees Celsius, is so much hotter than its surface, at 6000 degrees.

The SECIS instrument is made up of two cameras that are electronically linked. One looks through a 'green line' filter, while the other looks at white light. A total of four minutes of totality were filmed.
