What Are Those?

I filmed this today near Boise, Idaho around 2:45pm.
It is filmed on an iPhone SE and is in slow motion.
I counted at least 4 white objects zipping by or around what we know has been deemed The Sun.
What..Am I seeing?
When I looked over the footage, I immediately began shaking, as I had never seen something like this in the day time. Right next to that bright light is a brilliant (pun intended) place to hang out; no one will want to look there!
What is everyone's thoughts?
Again, this video is my original video. I've never seen anything like this before and I'm so fucking happy I caught this on camera.
