7 fireballs take exact path in sky at intervals.Walking dog in neighborhood I noticed 1st reddish what appeared like a ball of fire. It did not ascend but just appeared in sky. About 40 sec later a 2nd and another 40 sec a 3rd. They took exact same path. About 3-4 min later it happened again like the aforementioned. Then 3-4 min later it was just 1 but same appearance and same path as previous 6. I am a pilot so know aircraft lighting configurations and they were not aircraft and it was very quiet, no noise of jets. I thought maybe those Chinese lanterns, but they did not ascend from ground, just suddenly appeared in sky, approx. 45 degrees from horizon.
