Get Ready For The 2017 Total Solar Eclipse @ Holyoke Public Library

Join us on Monday, August 21!
In honor of the Total Solar Eclipse, on Monday, August 21st at 12 noon, the Holyoke Public Library will be screening “Hidden Figures”. The movie tells the groundbreaking story of three black female mathematician who helped shape the NASA space program.

Where and when can people see this total eclipse?
For those in the U.S., the August 21 eclipse begins on a beach on the west coast of Oregon, and ends on a beach on the east coast of South Carolina, making a narrow diagonal track across the United States. It goes through PORTIONS of Oregon, Idaho, Wyoming, Nebraska, a tip of Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina, and South Carolina. The map to the right shows you the areas it crosses.
Note that the path of the beautiful total eclipse really doesn’t go through any of America’s largest cities. It will be visible from Nashville, TN and parts of the St. Louis and Kansas City metropolitan areas. But all our largest cities will see only a partial eclipse. In Los Angeles, the eclipse will only cover 62% of the Sun, in Chicago 87%, in New York City 72%, in Miami 78%, and so on.
Smaller towns that are well placed for total eclipse viewing include Salem OR, Saint Joseph MO, Carbondale IL, Hopkinsville KY, and Columbia SC, among others. Visit our Eclipse Resource Center (see the link below) for interactive maps and get lists of towns or parks where the total phase will be visible.
How long will the total eclipse in August last?
The exact cosmic line-up that forms a total eclipse lasts only a short time in any given location. The total phase in 2017 will last a maximum of 2 minutes 40 seconds in the center of the Moon’s shadow. (This is short for a typical total solar eclipse; some can last 7 minutes.) The exact time it lasts depends on your location in the shadow band, and will likely be less than the maximum. The closer you are to the central line of the eclipse shadow the longer you will have to enjoy the spectacle. Also, the sky must be clear to see the eclipse.
If clouds hide the Sun the entire time, you’re out of luck, although it will still get dark.

Eclipse Glasses: Getting Them, Using Them
How to use your eclipse glasses safely:
1. Before you put the glasses on, make sure that the black plastic within the paper frames is not scratched or broken. Carefully check any glasses that children will be wearing as well.
2. Make sure that the glasses fit behind your ears; try moving your head around to make sure they don’t fall off. Also make sure any children under your supervision also have their glasses on so that the handles fit behind the ears. Keep children within your view while they are looking at the Sun.
3. Continue to remind everyone that when any part of the Sun’s bright disk is visible, it’s never safe to look at the Sun without the eclipse glasses or other indirect viewing technique.
4. Note that these glasses will not be able to protect you if you look at the Sun through a telescope that doesn’t have a certified solar filter attached to it.
When do you need to wear the glasses?
1. You need to wear the glasses whenever any part of the bright Sun is visible.
2. The only time it is safe to view the Sun without the glasses is the period of a few minutes when the eclipse is total (when the Moon completely covers the Sun.)
Can I use the glasses when there is no eclipse?
1. Yes, you can view the Sun any time with the glasses (but check them carefully each time before you use them to be sure there are no cracks or other damage)
2. When looking at the Sun through the glasses, you may occasionally be able to see tiny dark spots on it (these are groups of sunspots – cooler areas on the Sun’s surface that look darker to us.)
