Eclipse Aug. 11 1999 from Meru France. It was a bit cloudy. We had left Paris 3 hours earlier. The day before the freeway was moving at 140 kph. This morning is was a parking lot moving at about 15 kph. It seemed like everyone was leaving Paris to see the eclipse. We got off the freeway near the town of Meru about half way to Beauvals. The sky was overcast. We got off the freeway and headed for a small break it the clouds. After about 5 miles, the road ended in a parking lot. There were several groups of folks with eclipse goggles and to our surprise there was a small hole in the overcast through which we could see the sun through a high thin layer of clouds. For the next hour the sun came and went as lower clouds drifted over the hole in the overcast. With about 15 minutes to go the sun was gone. Three minutes to totality the cloud moved clear of hole just in time to see BailyÕs Beads and a fine diamond ring.
Eclipse Aug. 11 1999 from Meru France. This prominence probably extends out close to 30,000 miles.
Eclipse Aug. 11 1999 from Meru France. BailyÕs beads form as the last sliver of the crescent of the sun is blocked by high spots on the moon, mountain peaks or possibly high crater rims. These beads change as the moon occludes more and more of the sun until there is only one left that gives us the diamond ring. The light of the ring probably comes through a lunar valley.
Eclipse Aug. 11 1999 from Meru France. Because of the high overcast, the corona only extended about half the diameter of the sun. However , the high power of my video camera and telephoto lens clearly showed some great prominences. Within 5 minutes, the hole in the overcast was gone and it was raining. In our area, I would guess less than one percent of the area saw totality.
