Solar Eclipse 2017

Come join our Solar Eclipse Viewing Party!

This will be the first total solar eclipse to touch the United States for almost 40 years, and the first coast-to-coast across the U.S. since 1918. The last time a total solar eclipse occurred in the greater St. Louis area was 1442. St. Louisans can expect the next one in 2505.

In Webster Groves, we can expect the duration of totality to be around 1 minute and 15 seconds.

The partial phase will start around 11:49am and the totality will start around 1:17pm.

Our viewing party event is set to be held outside the front entrance of the library. Check out the Library’s Facebook page for updates and any changes in the following months leading up to the event.

 

Safety Do’s and Don’ts

DO NOT look at the Sun with your naked eyes – the Sun is so bright that it will damage your eyesight, perhaps permanently.

DO NOT attempt to look at the Sun through a normal telescope or binoculars – a single glance at the Sun’s focused light through the eyepiece could be enough to permanently blind you.

DO NOT try to look at the Sun through cloud or fog – enough harmful light will still pass through to damage your eyes.

DO NOT use sunglasses, smoked glass or welder’s glasses to look at the Sun – these DO NOT cut out the harmful ultraviolet and infrared light from the Sun that can do the real damage.

DO NOT use camera film/negatives – these are no protection against the hash light of the Sun.

DO NOT attempt to look at the Sun through transparent sweet wrappers, or foil. They DO NOT block enough of the Sun’s light to prevent you from damaging your eyesight.

DO NOT try to observe the eclipse by reflecting the Sun off a mirror, a CD, water in a river or even a puddle. The Sun’s light will still be too strong.

DO NOT combine specialist solar glasses with looking through binoculars or a telescope – the heat from the focused sunlight will melt through the glasses

DO NOT use solar filters that come as eyepieces for your telescope – all that focused light can cause the eyepiece to crack, letting through harmful amounts of sunlight that will blind you.

DO NOT use specialist eclipses glasses or Mylar film that has been damaged, either scratched or has holes. This will render them useless and result in you damaging your eyesight.

DO NOT leave the finderscope of your telescope uncovered if you are using your telescope to project an image of the eclipse – small children can accidentally look through it.

 

DO use dedicated eclipse glasses made of Mylar film. If purchasing solar glasses, check that they are CE approved and display the CE kite mark.

DO use eclipse glasses sparingly – continuous use can potentially see them damaged from the Sun’s heat.

DO use safe methods of observing the eclipse, such as projection through a telescope, or pinhole cameras. These are the safest ways to view the eclipse.

DO use specialist solar telescopes such as those manufactured by companies such as Lunt and Coronado.

DO supervise children at all times.

And finally, DO enjoy the eclipse safely!
