This photograph taken from the US satellite Terra displays the shade of the Moon on the Earth. As can be seen on the photo, Tokyo was under the thick clouds, so people were not able to observe the eclipse. However, when the clouds sometimes became thin, the sun became visible through the clouds.
When I came out of the building just before 12 noon, I couldn't locate where the sun was. However, when the clouds became thinner, I was able to spot the sun and took some photos with iPhone. I was a bit worried about my eyes because I had had retinal bleeding many times on my both eyes, and I should be extremely careful about ultraviolet sun light. However, this was such a thrilling event that I decided to take some photos anyway, considering that high frequency waves such as ultraviolet light should be scattered away by water molecules in the clouds. Of course, that filtering effect doesn't screen the higher energy (and shorter wave length) waves, so it's better not to see the sun in naked eyes. Fortunately, iPhone's LCD is big and clear enough to see the sun through it. I guess this is one of the safest ways to see the sun.
After taking photos, my eyes have been OK so far. However, maybe I should see an eye doctor to diagnose my eyes soon, just to be safe.
