Certain states will experience a total eclipse this summer; those of us in California can expect to see a partial eclipse. A limited number of safe viewing glasses will be available. Come watch the partial eclipse with us!
- When: August 21, 2017 at 9:30am
- Where: Main Library, West Auditorium - Off of Madison St.
125 14th Street, Oakland, CA 94612 / Phone# 510-238-3134
For those who can't join us on August 21st, NASA will be live streaming the eclipse via NASA TV and other channels. Live video streams from NASA and other locations across the country will be available here. The library is, unfortunately, entirely out of safety glasses (except for some set aside for the event itself), but you can safely view the eclipse by making a your own pinhole camera in 3D/2D:
Here is further information about viewing the eclipse safely:
The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special purpose solar filters, such as “eclipse glasses.” Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking directly at the sun.
REMINDER: Always inspect your solar filter before use; if scratched or damaged, discard it. Read and follow instructions printed on the back of filter. Always supervise children using solar filters.
WHEN WEARING GLASSES: Stand still and cover your eyes with your eclipse glasses or solar viewer before looking up at the bright sun. After glancing at the sun, turn away and remove your filter – do not remove it while looking at the sun. If you have traveled to view a total eclipse, remove your solar filter only when the Moon completely covers the sun and it suddenly gets dark. As soon as the bright sun begins to reappear, replace your solar viewer to glance at the remaining partial phases.
WARNING! Do not look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device. While using your eclipse glasses do not look at the sun though a camera, a telescope, binoculars, etc. – the concentrated solar rays will damage the filter and enter your eye causing serious injury.
According to the American Astronomical Society:
“How can you tell if your solar viewer is not safe? You shouldn't be able to see anything through a safe solar filter except the Sun itself or something comparably bright…If you glance at the Sun through your solar filter and find it uncomfortably bright, out of focus, and/or surrounded by a bright haze, it’s no good.”

In his memoir, eclipse chaser Frank Close studies the ever-growing spectator sport of eclipse watching and the fascination surrounding their popularity. From his first observation to the one he hopes to share with his grandchildren this Summer, Close’s pastime has evolved into full-fledged love affair with eclipses. One that has taken him from to a war zone in the Western Sahara, to the South Pacific, and into the African bush.
Journey through time to discover how astrologers, scientists, and philosophers have interpreted these rare events. Explore how eclipses have shaped science and were used by physicists to confirm Einstein’s theory of relativity. Author Tyler Nordgren takes readers on an entertaining look through eclipse history.
How were eclipses recorded in ancient times? Which Renaissance artist was partially blinded by an eclipse? Brimming with interesting facts and folklore, along with the science behind eclipses and why they occur, Mask of the Sun is a great introduction to the subject.
The historic eclipse of 1878 not only pushed astronomy to the forefront of the golden age, it was the year many braved the American West to watch the planets align and the sky to darken. David Baron vividly details how three pioneers set out to witness this phenomenon. Included are James Craig Watson, a Michigan astronomer racing to discover new planets, Thomas Edison a young inventor armed with his latest invention (the tasimeter), hoping to measure the heat of the Sun’s corona, and Maria Mitchell, a Vasser professor leading a female expedition out West to witness this rare event.
Looking for activities to do while observing the eclipse? Try watching it through a pinhole viewer, a household colander, or use common found objects like your fingers or fallen leaves to filter the sun’s rays and safely see the eclipse. This informative guide provides hands on tools designed for the whole family and is filled with tips, maps, and fun ideas to become a skilled skywatcher.
Author Aveni uses his unique background in astronomy and sociology to explore the effect eclipses have had on religion, science, and society. This rare look at both the science and cultural effect these spectacular events have had across the centuries is especially timely considering the upcoming pair of eclipses in 2017 and 2024.
