Hello Debbie, Like to give only a short commend. Read the book from : Meurois- Givaudan: ISBN 90-202-8109-7 - it is written in dutch, but must be available in english. The titel tranlated: a "lightbeam or beam of light or the flash of light " from the Sun. It descripes exactly what is going on. This book was given to me about 35 yeras ago ......
