My wife and i were driving to her place of employment in hazleton around 5 pm. it was still light enough to see aircraft in the sky. as we approached our destination i observed a bright white light in the sky to the south. at first i thought it was just an aircraft light, but it did not move, it just hung there in the sky stationary. i looked for the red & green navigation lights of an aircraft but there were none. after a few minutes, my wife also made a comment about the light and asked me if i saw it. i replied that i did and had been watching it for a few minutes. as we watched and discussed what we were watching the light suddenly blinked out leaving nothing in the sky. i could still see other airplanes in different areas of the sky because it was not yet that dark. i must stress that the light did not fade away, it just instantly went off. very weird.
