I have never seen a true solar eclipse. I always seem to miss them Have you ever seen one?
It's no wonder it can only happen at a new moon when the sun and moon are in conjunction and yes I have, 
I bet it was amazing. Can you tell me more about a solar eclipse?
It's crazy the disk of the sun if fully obscured. It's amazing. 
Is it normally only visible in certain parts of the world?
It can happen any where but it is rare that the Moon's orbit must cross Earth's ecliptic plane which also must happen in order for one to take place.
How often do they occur?
Between two and five times a year,
