The black object changed from a rectangle to a cross and had an orange glow.

My nephew first spotted a black object in the sky overhead.  We were at my parent's home to celebrate the New Year and my birthday which is on the 2nd.  We watched the object for at least 30 minutes.  My brother who has 20/15 vision said that the object changed shape from a rectangle to a cross and had an orange glow about it.  Additionally, this was a day of heavy chemtrail activity at my parent's home.  I counted at least 12 distinct chemtrails.  The object was beneath the chemtrails and was highlighted as the chemtrails passed overhead.  The object was stationary for some time but eventually disappeared.  This is the first time that I have witnessed a UFO.
