The Amazing Sky - Pictures

I don't know what was going on but yesterday and today, I saw something different. I've posted pictures here.

Today

I was looking up in the sky and I saw this view and it was a beautiful view so I took a picture.

Yesterday

I was walking and I noticed the sky and took this picture. But, what's weird is, it was evening and the sun was already down. And that can't be sun behind the clouds because the cloud was on the South.. And even if it was Sun, I know sun sets in the west...

Sorry for the bad picture quality.. They were taken from my Nexus 5 and I am not a good photographer.
