7 white lights South of Paulden, AZ. On 6/8/17 at 9:45 pm, that lasted until 10 pm.

Last night, on Thursday night, at approximately 9:45 pm until 10:00 pm, 6/8/17, my neighbor and I were sitting on my front porch, enjoying the clear cool evening.  
We noticed some strange lights to the South South East of our area fairly low in the horizon.  At first we noticed four white lights moving slowly up and down separately from each other and within about 2 minutes the number had increased to seven.  This lasted about 15 minutes. 
The lights looked to all be individual and moved slowly in an up and down pattern as well in opposite directions.  They also got brighter and dimmer, as the event was happening.  The lights appeared to be about 20 to 25 miles in the distance, and looked to be over the Prescott Valley to Dewey cities, from our position in Paulden. 
After about 15 minutes the lights started moving in a southwesterly direction, and slowly vanished from our view.  I did take a couple of photos with my cell phone camera  and I will try to forward with the report.  
I would like to know if anyone else had seen these as well?  This appeared to be a similar situation from what I have heard and seen of the Phoenix lights years back.
