800

About 10 PM.

Andy of Brecon was walking his dogs next to the river Usk, along the Promenade in Brecon. He saw a light in the sky to the south, in the area of Storey Arms in the Brecon Beacons, 3 to 4 miles away. He watched it for about ten minutes then filmed it on his mobile phone.

The light seemed to change colour from white to red at random, pulsing on and off and moving horizontally back and fore, sometimes above the horizon and at others below the horizon but in view, with the mountains behind.

'It definitely was not a plane or helicopter...... way too big for a drone. No sound at all.'
