This morning 8-26-17 we were coming west on desert inn at 6:50am the sun was brightly illuminating 3 dull grey spherical objects over the mountains one looked as if it had landed. the northern-most sphere broke into 3 smaller objects total then came right back together it slowly acended and moved in a southerly track during the sighting. the middle object hovered near the top of the mountain it did not appear to move. the object furthest south appeared to be landed on the mountain. photos were taken but the quality is very poor and through the windshield it is impossible to see anything of value. all the objects appeared to be the same color: a dull grey. the size of these objects must have been massive they were larger than a las vegas casino. they were perfect spheres no aircraft type appendages or lights to be seen. my girlfriend and i observed these for at least 10 minutes until buildings obstructed our view. i feel someone else had to see this, they were brightly lit by the morning sky and very large.
