Aug. 21, 2017 — the biggest show in the sky

You’ve been waiting for this moment (literally just 2.5 minutes) for a long time (38 years since the last eclipse), and you don’t want to miss any of the party. Here’s an itinerary of the morning’s extraordinary happenings:

10:22 The moon touches the sun’s edge. Use your glasses or another filter to safely experience First Contact.

10:23-11:41 Over the course of these 80 minutes, the moon appears to take an ever-growing bite from the sun as it becomes a shrinking sliver. Beads of light will shine through in certain places and disappear from others. Temperatures cool, and the the sky gradually darkens from deep blue to twilight to black.

11:42 The eclipse approaches totality. As the last bit of the sun’s sliver shrinks away, the corona appears, and the Baily’s bead effect begins. Beads of light dance around the sun, then fade away as the final bead brightens and expands into the highly-anticipated diamond ring effect.

11:43 The eclipse reaches totality. Remove your glasses for the next magical 2 minutes and 26 seconds. Catch an inimitable look within the universe as the eclipse creates a revealing hole cut into the sky. If you can pull your eyes away from this spectacle, notice the orange horizon that surrounds you. Most of all, appreciate this incredible but evanescent phenomenon.

11:45 Totality ends. Put your glasses back on to see the moon’s journey back across the sun.

1:09 The moon is completely out of the sun’s shadow, and the remnants of the total eclipse flame out as quickly as they flew in.

STARGAZING

Make the most of your eclipse experience

    • Watch somewhere in totality. Total solar eclipses and partial solar eclipses are vastly different experiences. In totality, you’ll see the famed diamond ring, the sun’s corona, unusual colors in the sky and stars during the day. Even if you’re in a location with 98 percent totality, you’ll miss the true experience. All of Casper is within totality, so we’ve got that covered.

 

    • Make a weekend out of it. While the eclipse occurs on Monday, Casper will be hosting dozens of activities and events leading up to the event. This is a festival, a celebration and a party. We want you on the guest list.

 

    • Get a filter in advance. Enjoying the eclipse safely is paramount to your experience, and the inexpensive yet stylish glasses will filter out the sun’s light as well as dangerous infrared and ultraviolet radiation so you can stare at the sun comfortably. While we expect the eclipse to take your breath away, we don’t want it to be in pain.

 

    • Keep the camera in your bag. You’re only going to get to see the eclipse for 146 seconds, and it will be the fastest 2.5 minutes of your life. Spend this time enjoying the experience, because even professional photographers with state-of-the-art equipment will take photos that don’t do the experience any justice. Still pictures can never capture what your eyes will see.

 

    • Hit the restroom before 10:30. You don’t want to be thinking about the bathroom during totality.

 

    • The eclipse will be over in a flash. You won’t believe that 146 seconds has passed — it will feel more like 8 . So appreciate this once-in-a-lifetime experience with special people in a special place.

 

 

 

 

The best seats in the house

Hours before the Moon prepares to make its journey between the Sun and the Earth thousands will set out to seek the perfect place to experience their moment in the Shadow. Luckily for you, Casper is entirely within the line of totality and for most that perfect place might just be your back yard or front porch. For others we’ve identified a number of viewing locations to meet your needs, whether you seek a location to accommodate your group with a number of tripods and photography equipment or a few choice seats for your family with concessions and amenities nearby.

We want this to be a great party for everyone, so please be respectful to nearby businesses and residents. Do not park or congregate in places that would inhibit anyone else from enjoying the show. Though you’ll feel like life stops during the eclipse, customary rules and laws aren’t suspended, so please stay out of private or restricted areas, and don’t cross fences or barricades. This is still the wild West, so enter open/public areas at your own risk, and inspect all areas before you and your family get settled. And it goes without saying, but we’ll say it anyway. Please leave the area in better condition than you found it so Casper will be just as beautiful the next time you’re here.

Your eclipse memories should be some of the brightest of your life, so we want to provide a safe experience. Because a huge part of this experience is looking into the sun, follow these rules to prevent serious eye damage or even blindness.

Never look directly into the sun without protection. Use any of the following:

  • Special Eclipse Glasses or welder’s goggles rated 14 or higher
  • Specially designed solar telescopes or solar binoculars
  • Telescopes, cameras and binoculars with approved solar filters or pinhole projector
  • PLEASE NOTE: Sunglasses DO NOT provide sufficient protection

During the 2.5 minutes of totality, protective eyewear is unnecessary, but please put your specialty shades back on after totality.

Official Safety Information from NASA

Looking directly at the sun is unsafe except during the brief total phase of a solar eclipse (“totality”), when the moon entirely blocks the sun’s bright face, which will happen only within the narrow path of totality (go.nasa.gov/2pC0lhe).

The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” (example shown at left) or hand-held solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun. To date four manufacturers have certified that their eclipse glasses and handheld solar viewers meet the ISO 12312-2 international standard for such products: Rainbow Symphony, American Paper Optics, Thousand Oaks Optical, and TSE 17.

  • Always inspect your solar filter before use; if scratched or damaged, discard it. Read and follow any instructions printed on or packaged with the filter. Always supervise children using solar filters.
  • 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.
  • Do not look at the uneclipsed or partially eclipsed sun through an unfiltered camera, telescope, binoculars, or other optical device. Similarly, do not look at the sun through a camera, a telescope, binoculars, or any other optical device while using your eclipse glasses or hand-held solar viewer — the concentrated solar rays will damage the filter and enter your eye(s), causing serious injury. Seek expert advice from an astronomer before using a solar filter with a camera, a telescope, binoculars, or any other optical device.

If you are within the path of totality (go.nasa.gov/2pC0lhe), remove your solar filter only when the Moon completely covers the sun’s bright face and it suddenly gets quite dark. Experience totality, then, as soon as the bright sun begins to reappear, replace your solar viewer to glance at the remaining partial phases.An alternative method for safe viewing of the partially eclipsed sun is pinhole projection. For example, cross the outstretched, slightly open fingers of one hand over the outstretched, slightly open fingers of the other. With your back to the sun, look at your hands’ shadow on the ground. The little spaces between your fingers will project a grid of small images on the ground, showing the sun as a crescent during the partial phases of the eclipse.A solar eclipse is one of nature’s grandest spectacles. By following these simple rules, you can safely enjoy the view and be rewarded with memories to last a lifetime.

Additional Safety InformationAn eclipse is a rare and striking phenomenon you won’t want to miss, but you must carefully follow safety procedures. Don’t let the requisite warnings scare you away from witnessing this singular spectacle! You can experience the eclipse safely, but it is vital that you protect your eyes at all times with the proper solar filters. No matter what recommended technique you use, do not stare continuously at the sun. Take breaks and give your eyes a rest! Do not use sunglasses: they don’t offer your eyes sufficient protection. One excellent resource for safe solar eclipse viewing is here:  nasa.gov/content/eye-safety-during-a-total-solar-eclipse

Viewing with Protection — Experts suggests that one widely available filter for safe solar viewing is number 14 welder’s glass. It is imperative that the welding hood houses a #14 or darker filter. Do not view through any welding glass if you do not know or cannot discern its shade number. Be advised that arc welders typically use glass with a shade much less than the necessary #14. A welding glass that permits you to see the landscape is not safe. Inexpensive eclipse glasses have special safety filters that appear similar to sunglasses, but these do permit safe viewing.
Telescopes with Solar Filters – Eclipses are best viewed directly when magnified, which means a telescope with a solar filter or solar telescopes. These will give you a magnified view that will clearly show the progress of an eclipse. Never look through a telescope without a solar filter on the large end of the scope. And never use small solar filters that attach to the eyepiece (as found in some older, cheaper telescopes.) Pinhole projectors – Pinhole projectors and other projection techniques are a safe, indirect viewing technique for observing an image of the sun. These provide a popular way for viewing solar eclipses.
Related projection methods — One viewing technique is to project an image of the sun onto a white surface with a projecting telescope.  This is explained further here: astrosociety.org/education/publications/tnl/05/stars2.html. The Exploratorium demonstrates how to view a planet in transit or an eclipse safely by projecting the image with binoculars: exploratorium.edu/transit/how.html. There are commercially available projection telescopes as well.Besides eye protection during solar eclipse viewing, one needs to pay attention to their personal needs and surrounding.  Below are some additional safety tips for eclipse observers before, during and after the August 21, 2017 solar eclipse.
