Airplane like object stationary in the north sky emitting red, white, and green (or blue) light.I am at 43 degrees 59 minutes 2 seconds North, 89 degrees 33 minutes 18 seconds West. The last two nights we have observed an object about 10 degrees above the horizon and about 10 to 12 degrees East of true North stationary in the sky. It is a small source of alternating light of red, white, and green (or blue). It is small enough to have no shape, but is brighter than any star in the sky. We have observed it for several hours each night over the last three nights. It remains stationary the entire time that we observe it. I reported it to our local Sheriff's department, their officers have observed it and concluded that it is a planet whose light is being affected by the aurora. I pointed out, to them, that there are no planets in the far northern sky, but they were happy with their explination. Hope you can tell us what it is.Thanks, ((name deleted)) I don't think that this is a UFO, but would like to know what it is.((NUFORC Note: We spoke with this witness and believe that the object he viewed probably was a celestial body. He will look again on the next clear night. PD))
