Driving east down valley rd into e valley rd, observed 3 large sets of 5 bright lights in the eastern sky. thought at first they were houses lit up on the hills near chaffee crossing, when i realized it was the wrong angle to view the hills i thought they might be planes flying low in formation. only the set of lights on the left seemed to be moving, the other two were clearly stationary. something seemed odd about the lights, i wasn't able to see them by the end of e valley rd after they were obscured by tree cover so i drove in circles for 20 min trying to see them again or anything that could explain the lights, like aircraft landing at the nearby airport, but didn't see anything. likely it was nothing, but an uneasy feeling about the lights made me go ahead and report it.
