Time: 18:45 (6:45 PM).Date: 11/02/2013 (2 November 2013).Location: Esch-an-der-Alzette, Luxemburg.Description of event: Walking in the hills north of Esch-an-der-Alzette with three members of the same family. We notice ten small orange lights flying in "V" formation' near the city, followed by another, slightly larger, "V" formation' of orange lights seconds later. Clueless to what we saw. Too fast to be balloons, too numerous to be aircraft. Air traffic over Luxemburg is usually small.((NUFORC Note: The party who submitted the report elects to remain totally anonymous, and provides no contact information, so we are unable to contact the witness.
