UFO Sighting in Peoria, Arizona on October 24th 2015 – Like a bright perfectly white light shining down on a clear day

Riding in a side by side on the desert, looked over at my husband driving saw a bright round light my husband looked said cool we looked again and it was gone we kept looking saw s airplane and we questioned what we just saw a star or planet visible. Didn't move stationary. Amazed how perfectly white light on such a clear day wasn't the sun or a plane. Looked away to my husband to say wow what is that and it was gone.
