Join us as we experience again the excitement and wonder of a celestial event that has captured mankind's imagination for thousands of years!
The March solar eclipse will be viewed by people all over the world either directly or through some communication medium. There will also be many people that will not have access to the eclipse. Your interest in the eclipse and expertise in viewing the sun can be a resource to many thousands of people who would otherwise not be able to view this amazing event.
NASA would like to thank you for your help in communicating the wonder of this celestial event to the public. We have designated this part of our web site just for amateur astronomers to assist you in viewing the eclipse and helping others view it. Once registered, you will receive a packet of NASA materials. You can also complete the requirements for the NASA Eclipse Observing Certificate Program and receive a certificate of completion. Our site has information on holding an eclipse party and references for activities and historical, technical, and scientific information about eclipses.
Please join us as we experience again the excitement and wonder that has captured mankind's imagination for thousands of years.
Before the advent of modern atomic clocks, studies of ancient records of solar eclipses allowed astronomers to detect a 0.001 second per century slowing down in Earth's rotation.
