Orbs of light behind clouds circling around each other.

Looking east, above the cloud layer were two - but at times three - orbs of light. They were about 45 degrees above the horizon and stayed within a small area in the sky.  The lights looked large but may have been enlarged due to the glare on the clouds.  The orbs would track over the area in either oval or figure-8 patterns, often circling around the other. The third orb would appear out of one but disappear soon after.  The motions were not uniform, although they were not erratic either.  It looked as though they would leave a sort of chem trail behind them, and the general area they were n cleared up of clouds - but not entirely.  Could not have been spotlights, the source of the light was above the layer of clouds.  A fire alarm was set off nearby in the direction of the orbs, not sure if EM related but worth mentioning.
