Green Glowing object shot off at very fast speed.Saturday, July 30th. 2016. Approximately 3:10 am.Haleiwa, Oahu, Hawaii.Green, bright glowing object traveling at aircraft speed coming in on approach to the coast line.As it came in to a certain distance, far enough away for me to not see detail, it dimmed to a dull green color, as if someone threw a switch.Following right after it dimmed, it shot off parallel to the coast line at a very high rate of speed.As it shot off, it did not appear green any longer, but instead a dull white.
