On January 14, 2015, it was snowing much on the city of Tamworth (located in Staffordshire, United-Kingdom). An inhabitant took a photo of landscape. Surprisingly, two mysterious lights were flying at this moment appeared on image!

Witness report:

I was at work at the time on my breakthrough at 10 past two in the morning I was standing outside having a cigarette and it started to snow heavily so I took a picture on my phone when I got home I checked the picture and there are 2 green orbs floating above.
