orb of light flickers but then dissapearsFor the past two years, I have been witnessing a small orb of light which looks to be like burning embers that gently float across the sky but disappears, when i try to drive closer to it. Happens at about the same time at night maybe 30 minutes after the sun has set.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. We suspect that the witness implies a nighttime sighting, and we have amended the time above. PD))
