I have observed this object twice now on 8/15/14 and 8/17/14. It ascends from the west rapidly as a diffused blue light. It initially appears like a spotlight whose beam is diffusing on a cloud. There were no clouds in the sky both nights. Very clear conditions. The light moved across the shy rapidly. The first night it flew upwards and downwards at rapidly then. disappred. The second night the light ascended higher and made its way east towards my location. As it did it went from a diffused light ito a very well defined orb. It hovered and pulsated a very brilliant bluefish light. After 10 seconds or so it began moving west again at a high rate of speed. It's path came near a commercial airliner to the west at which time it turned away from it and diffused itself as though it was hiding. It skirted around the planes vicinity then proceeded a little north then again decended from my view from the same place it appeared.
