What to expect if you observe the solar eclipse Monday & how to watch it safely:
What to expect:
1. Watch the linked video below for a good presentation of what you can expect
2. Your experience will vary depending on whether or not you are watching from within or outside the zone of totality
3. If you are going to be inside the zone of totality, the closer you are to the centerline of that zone, the longer totality will last
4. You want to try and observe the eclipse by having a clear, unobstructed view to the southwest (ranging from southward to westward)
5. If you are able to observe the eclipse from a sufficient height, you will be able to see the shadow of the moon (totality) approach you
6. As mentioned in the video, you can expect an eerie silence to descend as you near and during totality. This is because the surrounding wildlife (birds, bees, insects, and other animals) nearby believe that it has become nighttime
7. Also expect a quick drop in temperature during and after totality. The temperature COULD drop by as much as 5o C (10o F) with the lowest temperature occurring about 2 minutes after the end of totality. If you are outside the zone of totality, this effect is far less pronounced
How to observe the eclipse safely:
If you have SOLAR ECLIPSE glasses (or viewers):
1. Verify that your eclipse glasses are ISO 12312-2. The glasses should also carry the ISO logo, the name of the certifying agency, and the manufacturer's name & address
2. There is a limited window when you can observe the eclipse without the solar eclipse glasses. This is ONLY during TOTALITY, more than 15 seconds AFTER (and BEFORE) the Baily's Beads occur. At any other time, including at ALL times if you are not within the zone of totality, eye protection is necessary
3. The partial phases of a total solar eclipse eclipse progress quite slowly. There is no need or point to watch continuously. You can, instead, take a brief glance every few minutes. The motion of the Moon across the Sunโs face will be readily apparent
4. Irrespective of the previous point, it is recommended that you limit your viewing of the sun pre and post totality to intervals of a maximum of 3 minute
5. Do NOT look at the sun when putting on or taking off the solar eclipse glasses. Instead, look away from the sun both when you put them on and take them off
6. Permanent blindness is a RISK if you fail to follow these guidelines. There are no pain receptors at the back of your eye, so it is possible to burn out the rods and cones of your eye (what makes it possible to see) without ever realizing it is happening until it is too late
7. Do NOT look at the sun through an unfiltered camera, telescope, binoculars, or any other optical device while using your eclipse glasses or handheld solar viewer in front of your eyes โ the concentrated solar rays could damage the eclipse glasses and enter your eyes, causing serious injury
8. Always supervise children using solar filters
If you do NOT have SOLAR ECLIPSE glasses (or viewers):
1. View the solar eclipse indirectly using a pinhole projection. For example, cross the outstretched, slightly open fingers of one hand over the outstretched, slightly open fingers of the other, creating a waffle pattern. With your back to the Sun, look at your handsโ 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 any solar eclipse. Or just look at the shadow of a leafy tree during a partial eclipse; you'll see the ground dappled with crescent-shaped Suns projected by the tiny spaces between the leaves. A colander makes a terrific pinhole projector, as does a straw hat, a perforated spoon, or anything else with lots of small holes in it. Do NOT look at the Sun through the pinhole(s)
2. View the solar eclipse indirectly, either online or on television
