Blue/purple orb seen from North Table in Golden, CO.I stepped out onto my front porch and looked into the northeast sky. I noticed what looked like a blue/purple orb flying in a T shaped pattern. It flew very slowly, and very directly. When it changed direction, it did so immediately. When it first caught my eye around 1am, it was moving to the left, then headed down. Headed back up, then moved left again. Stopped for a brief minute, and when it did, it became a semi-solid/pulsating randomly white light. When it began moving again to the right, it became the blue/purple orb it had been when it first caught my eye. After moving for a brief moment it stopped, changed to a white light again, and this is where it sat for a solid 20mins. Then, out of nowhere, it became the blue/purple orb once again, this time moving straight up for a split second, moving significantly faster, and then it was gone.((NUFORC Note: Source of the report elects to remain totally anonymous; provides no contact information.
