20. STEPS OF TOTALITY Partial eclipse : 18 minutes before total eclipse begins about 80% of the Sun’s diameter is gone! Partial eclipse : Nearly ½ of the Sun’s disk is eclipsed. (TSE of 1999 August 11 Lake Hazar Turkey)
21. DIAMOND RING AT 2 ND CONTACT Before totality begins, the corona appears during diamond ring effect. (TSE of 1999 August 11 Lake Hazar Turkey)
22. OUTER CORONA (TSE of 1999 August 11 Lake Hazar Turkey) VISUAL CORONA
23. FINAL DIAMOND RING (TSE of 1999 August 11 Lake Hazar Turkey) At 3rd contact the diamond ring effect heralds the end of totality.
24. Partial eclipse : Nearly 4/5 of the Sun’s diameter is still covered by the Moon.
25. Partial eclipse : Half of the Sun’s diameter is still covered 40 minutes after the totality ends.
26. Partial eclipse : The final 20% of the Sun remains covered by the Moon.
36. HOW TO MAKE A SIMPLE PINHOLE PROJECTOR TO VIEW TSE SAFELY There are safe ways to view the sun. The simplest requires only a long box (at least 6 feet long), a piece of aluminum foil, a pin, and a sheet of white paper. 1. Find or make a long box or tube
37. HOW TO MAKE A SIMPLE PINHOLE PROJECTOR TO VIEW TSE SAFELY 2. Cut a hole in the center of one end of the box. 3. Tape a piece of foil over the hole. 4. Poke a small hole in the foil with a pin.
38. HOW TO MAKE A SIMPLE PINHOLE PROJECTOR TO VIEW TSE SAFELY 5. Cut a viewing hole in the side of the box. 6 . Put a piece of white paper inside the end of the box near the viewing portal.
39. HOW TO MAKE A SIMPLE PINHOLE PROJECTOR TO VIEW TSE SAFELY Point the end of the box with the pinhole at the sun so that you see a round image on the paper at the other end. If you are having trouble pointing, look at the shadow of the box on the ground. Move the box so that the shadow looks like the end of the box (so the sides of the box are not casting a shadow). The round spot of light you see on the paper is a pinhole image of the sun. Do not look through the pinhole at the sun! Look only at the image on the paper.
40. TSE THAT WE OBSERVED IN TURKEY ON 29 th MARCH 2006 On Wednesday, 29th March 2006, the shadow of the Moon swept a band starting from Brazil, through Atlantic Ocean, Gold Coast of Africa, Saharan Dessert, Mediterranean Sea, Turkey, Black Sea, Georgia, Russian Federation, northern shores of Caspian Sea, Kazakhstan; ending in Mongolia. The duration of totality was less than 2 minutes near the sunrise and sunset limits, but as long as 4 minutes and 7 seconds in Libya, at the moment of greatest eclipse. The path of totality was 180 kilometers wide at that moment. It was observed over many regions in Turkey. March 29th, 2006 Total Solar Eclipse had a duration of totality of about 4 minutes in Antalya.
47. SHADOWS Projected images of the Sun may be seen on the ground in the small openings created by interlacing fingers, or in the dappled sunlight beneath a leafy tree. Binoculars can also be used to project a magnified image of the Sun on a white card, but you must avoid the temptation of using these instruments for direct viewing.
