Vertical string of lights in Arizona.

At 2;20 AM Arizona Time 30 September 2015 I was outside taking the trash to the curb. I looked up at the moon, which was directly overhead and as I turned I saw a group of blinking lights in the South-East.
The lights were stationary and blinking red, green, and white.  I took out my cell phone to check the compass direction and discovered that it was useless.  I was looking at what I know to be Southeast and my compass inexplicably read West.  I did, however, have a pair of opera glasses within easy reach so I went in to find them.
Using the opera glasses I was able to make out a vertical string of blinking lights, in red green, and white.  The string of lights hung in the sky like a string of multicolored pearls for over an hour.  During all that time all I could do was watch.
