I got up early this morning.

I got up early this morning. I saw the dawn on  from the top floor of our building. It was  beautiful. The weather forecast said it would be sunny today. I have am in a good mood to remember more English words today. Come on!

Notes: Good.

With this sentence " I saw the dawn on the top floor of our building". It is possible that is actually what you did this morning. The sentence would mean that you were doing something like watching a reflection of the early sun.

Have you ever seen the dawn sun over the ocean from a beach in the morning ?

That is well worth seeing.
