Observing a Solar Eclipse
- At 3pm in Egypt, I began to observing the solar eclipse.
- I used convex lens to produce the image of the sun on a white board.
- This method helped me to trace the change of the sun shape and protect my eyes too.
- I watched on the same time the total solar eclipse on the Internet.
