Both my wife and I saw this. We've both seen fireballs at night but this was in daylight. Sun was just below our line of sight and the sky was still very bright. Hard for me to figure out how bright it was considering the day conditions, but I would guess as bright as a quarter to half moon. It was spectacular!

Remarks
One object broke into at least 3. Of the 3, one was a lot brighter. All 3 continued same trajectory but travel was into setting sun and lost them.
