Two lights moving upward together, blinking then disappearing.Weather was a mix of bright clear skies and intermittent clouds. Sitting out with family, I had been looking at the stars. There was a blinking light very high up that caught my eye. I thought it was an airplane, but watched for a moment to see that it was two separate lights side by side. They did not travel North, South East or West, only up.One light would blink, the other would blink, then they both moved upward –what appeared to be a short distance - to another position. It seemed that one of them began its move slightly before the other. They stopped, went through the same routine, one blinked, the other blinked then both moved farther away up into the sky. This happened one more time, one blinked the other blinked then moved upward. At this moment, they both seemed to blink off as they moved up farther into the sky and I could no longer see them.When I saw them blink the first time, I motioned to my sister to look. She caught a quick glimpse of the last movement they made upward, then out of sight.These objects were very high up, presumably out of the atmosphere. From where I was standing on Maluniu Av, I was looking almost straight up, slightly toward Kalaheo High School area.
