A large, extremely bright orange, glowing orb travelled north to south, paralleling the Oregon coastline.My wife and I observed a very large extremely bright orange, glowing orb that tracked north to south some distance off the ocean shore paralleling the coastline. The surface of it looked like a molten liquid, except for a relatively faint difficult to see grey shape in the center. This molten appearance reminded me of a NASA photo of the surface of the Sun except that, unlike the Sun, the edge of it was very sharply defined. The bottom of it emitted a reddish color.It remained level at relatively low altitude for about 15 to 20 seconds and then pulled up at sharp angle and rose at a tremendous rate of climb; it momentarily appeared to stop and then continued to climb rapidly. The light was so bright that it illuminated very high thin cirriform clouds in the dark sky as it passed through their altitude. It made no audible sound. This took place approximately ninety minutes after sunset.I hold a commercial pilot license and previously worked as a certified flight instructor. I now work as a technical analyst in aerospace engineering.
