What? Where? When?
Good news for all the people living in America. On 21st of August they will witness an astronomical phenomenon which hasn’t been seen in over 38 years. The last a total solar eclipse was visible in America, was in 1979. Therefor if you miss this opportunity you will need to wait another 7 years until 2024. The total solar eclipse will be visible only on a narrow corridor as you can see in the image below. In the rest only a partial eclipse will be visible. This narrow corridor consists of the following states: Oregon, Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina and South Carolina (a tiny corner of Montana and Iowa are also inside the path).
The maximum duration of this phenomenon will be 2 minutes 40 seconds. Therefor you will not have enough time to make adjustments of your camera if you want to take the shot. You should prepare in advance.
What is a solar eclipse? What you will see?
This celestial event is more common than you would think. The only issue about solar eclipses is that they happen quite often over sea. However, for those who don’t know what a solar eclipse is, I can tell you that it is a celestial phenomenon. It happens when the Moon and the Sun are perfectly aligned. Thanks to the Moon’s size, this has the perfect diameter in relation to the distance of the Sun.
The dark gray region between the Moon and Earth is the umbra. It is the place where the Moon completely obscures the Sun. The small area is where the umbra touches Earth’s surface. This place is where a total eclipse can be seen. The larger light gray area is the penumbra. Consequently it is the place where you will see only the partial eclipse. This is the explanation behind why the total solar eclipse will be visible only on a narrow corridor.

It is very important to highlight that under no circumstances should you watch the solar eclipse with the naked eye. You need to take precautions otherwise you could harm your eyesight. Do not view or photograph the eclipse without the use of solar filters and appropriate eye-wear designed for viewing the solar eclipse. For instance you can pick one from amazon.
