The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
Me my partner and my son (age 10) were driving toward derry city (northern ireland) via the old letterkenny road at around 5pm new years eve and were admiring a waxing moon above the river foyle. we collectively observed a large green disc shape, dull behind the clouds then emerge out and move slowly across the sky for about 1-2mins, then it came to stop and sped off at an unusually fast pace and dissapeared. whilst this was happening we were asking eachother could it be a plane, or helicopter but it did not follow any of the usual patterns. we are used to lots of helicopter/drone activity here in derry due to the troubles but this one has baffled us. it was unlike anything we have ever witnessed.
