How to View the 2017 Solar Eclipse Safely



A solar eclipse occurs when the moon blocks any part of the sun. On Monday, August 21, 2017, a solar eclipse will be visible (weather permitting) across all of North America. The whole continent will experience a partial eclipse lasting 2 to 3 hours. Halfway through the event, anyone within a roughly 70-mile-wide path from Oregon to South Carolina (https://go.nasa.gov/2pC0lhe) will experience a brief total eclipse, when the moon completely blocks the sun’s bright face for up to 2 minutes 40 seconds, turning day into night and making visible the otherwise hidden solar corona — the sun’s outer atmosphere — one of nature’s most awesome sights. Bright stars and planets will become visible as well.

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 (https://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 (https://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 Information


An 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:  http://www.nasa.gov/content/eye-safety-during-a-total-solar-eclipse(link is external)

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 (link is external) -- 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: http://www.astrosociety.org/education/publications/tnl/05/stars2.html(link is external).
The Exploratorium demonstrates how to view a planet in transit or an eclipse safely by projecting the image with binoculars:

Hiking Tips

Many roads leading to key vantage points on public lands may be closed to motorized traffic during the eclipse for safety and capacity reasons, vantage points may only be accessible by foot.

Practice Good Stewardship of our Trails / Roadways:


You can help to take good care of our trails and roadways so that others may enjoy these areas for years to come by practicing some of the following actions:
  • Don't Litter... take along a trash bag or other receptacle for collecting your trash so that you can deposit it in the proper trash receptacle.
  • Make sure that you hike / walk on the designated trail or roadway in that area. Check with your destination ahead of time to ensure that the area you plan to hike in is allowed.
  • Don't hike in areas where it is not permitted. These areas have been declared "off limits" to hikers to protect wildlife, vegetation, or for your safety.

Safety While Hiking:

  • Wear proper clothing and footwear, according to the terrain and season
  • Be courteous and remember that you are sharing the trail or roadway with other hikers and recreationists
  • Do not hike or walk on unauthorized trails or roadways
  • Bring along extra safety items such as water, flashlights, maps, and a cellphone or radio

Wildland Fire Minute


While the past six months in the Pacific Northwest have been cooler and wetter than normal, June, July, and August are predicted to be warmer than average. We will likely have a slower start to the fire season due to slow melt off of snow at the higher elevations.

Most years, lightning causes the majority of fires in the Pacific Northwest, this year we will have the added human factor of up to a million people visiting Oregon during the peak of fire season to witness the total solar eclipse. We are ramping up our fire prevention efforts with that in mind.

This year, we have a new partner in fire prevention. While we’ve worked with Rangeland Fire Protection Associations in fire suppression efforts for years, we are now embarking on a joint fire prevention campaign. YOU can help as well, by:

• ensuring campfires are cold to the touch before leaving them;
• avoiding parking or driving in dry grass; and
• remembering that fireworks and exploding targets are prohibited on Federal lands.

To learn more about the latest wildland fire conditions in the Pacific Northwest head on over to: http://gacc.nifc.gov/nwcc/
