A solar eclipse is the astronomical phenomena in which the moon partially or totally covers the sun and darkens the day in a momentary way, always seen from Earth. For those of you interested, it is much better to visit the Wikipedia page that explains correctly what an eclipse is and what types there are.

As a mandatory recommendation, please do not look directly at the sun, sunglasses or any device or filter that is not recommended by a specialist. Mandatory to say you should not use binoculars, never do that. It is best to make a small hole in a sheet of paper and project the light through it in a cardboard, if it can be dark better.
Astronomy is a topic that fascinates me, I have a telescope and especially in summer, every time I can I escape to the mountains to observe the sky although if there is not a single cloud, sometimes from home we can observe the moon.
Enjoy the eclipse with caution, occur seldom.
I am Groot! :D
