Eclipse 2017 | nightwise

All of North America will see a partial solar eclipse, and a narrow swath from Oregon to South Carolina will experience a total solar eclipse. This will likely be the most observed celestial event in US history. Make your plans now.

Sun Funnels

The Sun Funnel is a telescope accessory that allows a group of people to observe a magnified image of the sun safely.

Instructions to Build a Sun Funnel, updated for the 2017 eclipse by Rick Fienberg, includes images, tips, and precautions.

See video for introduction of 3D-printed version of the Sun Funnel . Additional tips are at my Sun Funnel page.

Future Eclipses-USA

From the Mr. Eclipse Eclipse Primer:

"The last total solar eclipse visible from the continental U.S.A. occured on Feb. 26, 1979. A total solar eclipse was visible from Hawaii and Mexico on July 11, 1991. The next two total solar eclipses visible from the U.S.A. occur on Aug. 21, 2017 and Apr. 8, 2024."
