今年八月的天空將有一件你不想錯過的精彩活動。 所以這裡提供大家一個安全指南來觀看「日全食」!

2017年八月二十一日星期一,西海岸從早晨開始,東海岸從早中到中午開始,北美的民眾能夠看到至少一部分的日全食。

看日全食唯一需要的特殊設備是觀日(食)眼鏡。從一些便宜的卡紙型眼鏡到較貴的塑框型眼鏡都可以在零售商店購得。

如果不打算用觀日(食)眼鏡,可以作個簡單的針孔相機,將日食的圖像投射到地面或牆壁上。看日食的投射(你背向太陽)是在沒有保護眼睛工具情況下,一個觀日食的安全方法。

照相機很好用,可以抓住這個過程; 而望遠鏡和雙筒望遠鏡可用於近距離觀察月球邊緣,太陽表面(日偏食期間)或太陽風線(日全食期間)的特徵。只是,正如太陽的輻射會損害沒有保護設備的眼睛一樣,它也可能會損壞未受保護的裝置。如果您想使用照相機或望遠鏡,請務必購買特殊的聚酯薄膜過濾蓋,以套住相機鏡頭或蓋住望遠鏡的端部。

警告: 在看日全食的過程中,要小心,不要冒險地直接用眼睛看。

  • 記住 – 不論時間長短,在日食進行期間,沒有適當保護眼睛的設備,不要直視太陽。
  • 使用觀日(食)眼鏡,一定要檢查並確定鏡片是否完好無損的。如果聚酯薄膜鏡片有破損,就丟掉不要用。
  • 不要使用沒有過濾蓋的望遠鏡或雙筒望遠鏡觀看太陽。 即使戴聚酯薄膜的過濾眼鏡也是,因為聚焦的陽光可以通過過濾器燒傷眼睛。
  • 請勿使用一般的太陽眼鏡。 無論鏡片是多麼黑,或是防紫外線的等級為何,當你直視太陽時,一般的太陽眼鏡都不足以保護你的眼睛。
  • 14號焊接工人所使用的黑色玻璃護目鏡片確實提供足夠的保護,但必須確定所使用的護目鏡片真具有這個等級(一些弧焊使用的設備可能不夠,使佩戴者的眼睛容易受到太陽的輻射)。

There’s an amazing event going on in the sky in August of this year, and it’s one you’re not going to want to miss. So here’s your guide on to safely watch the total solar eclipse!

On Monday, August 21, 2017, starting in the morning on the west coast and the early to mid afternoon on the east coast, residents of North America will be able to see at least part of a Total Solar Eclipse.

The only special equipment needed to watch the event is a pair of solar viewing glasses or eclipse glasses. Inexpensive ones made from cardstock are available from various retailers, as are more expensive ones with plastic frames.

If obtaining eclipse glasses is not an option, a simple pin-hole camera can be constructed, to project an image of the eclipse onto the ground or a wall. By watching the projection of the eclipse (with your back to the Sun), this is a safe way to view the event without eye protection.

Cameras are good for capturing the event, and telescopes and binoculars are useful for either getting a closeup look at the edges of the Moon, the surface of the Sun (during the partial eclipse), or the lines of the solar wind (during totality). Just as the Sun’s radiation can damage unprotected eyes, it can also damage unprotected equipment. If you wish to use a camera or telescope, be sure to purchase special Mylar filters to fit over the lens of the camera or to cap the end of the telescope.

WARNING: Be very careful and do not take chances with your eyesight during this event.

  • REMEMBER – Do not look directly at the Sun without the proper eye protection, for any length of time, even during a solar eclipse.
  • Use solar viewing glasses or eclipse glasses, and check to ensure that the lenses are intact. Discard any pair where the Mylar lenses are damaged.
  • NEVER look at the Sun using an unfiltered telescope or pair of binoculars. This applies even if you are wearing Mylar filter glasses, as the focused sunlight can burn through the filters.
  • Do not use normal sunglasses. No matter how dark they are or what their UV rating is, normal sunglasses will not be enough to protect your eyes as you look directly at the Sun.
  • #14 welder’s glass does offer adequate protection, but be sure that the equipment actually has this rating (some arc-welder equipment may not, leaving the wearer’s eyes vulnerable to the Sun’s radiation).
