About the total solar eclipse on July 22, 2009 ... urgent!

1. It is best to watch the solar eclipse at the top of the mountain in the eastern suburb of the city in the morning. Pay attention to safety in suburbs and mountaineering. Never look at an eclipse directly with the naked eye, even if it is a lunar eclipse. See 4. See for details.

2. If it is a total solar eclipse, you can see that it suddenly turns black for a few minutes, and then it will dawn. It's interesting, but you should pay attention to safety when it suddenly gets dark.

Then, before the food is eaten, after the birth of light, you can see the scene of "Bailey Pearl".

During the eclipse, you can see the magnetic radiation of the corona, prominence and solar poles.

If it is a partial solar eclipse, you can see the mottled reflection of leaves on the ground through pinhole imaging principle, which is semicircular and very ornamental.

I don't know what you are asking. The eclipse will cause rivers and oceans to rise. There is also the need to pay attention to safety when the total solar eclipse suddenly gets dark, especially in crowded places.

4. No, sunglasses are useless. Use a professional eclipse mirror. It's also very cheap, just a few dollars. Or go to the hardware store to buy sunglasses for welding. Even welding sunglasses should use two overlapping pieces.

5. Direct shooting is certainly possible. If you shoot with a filter, the effect will naturally be better, but the filter used for professional shooting is very expensive.

It's late at night, and I'm bored. Few people come to answer your questions, so I'll help you answer them and make publicity for astronomy.
