Early morning around 0100; I couldn’t sleep and was looking out the window and noticed 4 blinking red lights, above the horizon, that were in a vertical row. Since we had just moved into this house, I wasn’t familiar with the neighborhood vista yet, and thought it was a radio tower of some kind, that’s how still they were.

Then, all of a sudden, the two middle lights moved horizontally to make a diamond formation; this pattern was held for a few seconds and then the bottom light moved up between the two horizontal lights, forming a chevron, then in a split second they moved higher into the sky and were gone into the darkness of the night.  
From the time I noticed the lights, until they were gone, less than a minute had elapsed.
