What is an eclipse?

An eclipse will occur on Monday if you live in the United States. However, I am blind and will not look at it. So, I will use this post to understand what I think it will look like and what it is. ___
The word is eclipse and according to the dictionary it means:
an obscuring of the light from one celestial body by the passage of another between it and the observer or between it and its source of illumination.
a phase during which the distinctive markings of a bird (especially a male duck) are obscured by molting of the breeding plumage. ___

Monday will be the first one. What I think it will look like: the yellow sun will be blacked out by a shaddow, which will cover most of the sun excluding the part around the edge. It will darken the sky. Am I correct?

Word of the day – Commit

The word for today June 23, 2017 is Commit.

carry out or perpetrate (a mistake, crime, or immoral act); pledge or bind (a person or an organization) to a certain course or policy; send, entrust, or consign, in particular.

I cannot commit to Portland State because their website cannot be accessed on my Laptop.
99% of my work will be done online and if I cannot access the website why waste my money?
