Linear strand of approximately 5-10 white lights moving quickly and silently across the sky

The object appeared in the east sky, above the silhouette of the mountains, north of where I was standing.  There was a strand of white lights, approximately 5-10 lights, running horizontally.  The object then quickly moved southward in an irregular pattern-it zigzagged a little and rotated, causing the lights to shift from running horizontally to vertically.  The lights remained in the vertical pattern.  The object moved to a point slightly south from where I was standing and stopped.  It stayed in that position, still above the silhouette of the mountains.  The object remained there for approximately a minute.  The sun was starting to rise, so the lights were no longer visible.  The event lasted between 1 to 2 minutes and there was no sound coming from object.
