Pulsing Multi Coloured Orb Stapleford Nottingham

My 6 year old daughter had been to the shop with my dad and she was the one who spotted it first. She was scared and ran in the house shouting mummy "the aliens are here!!". We laughed and said don't worry it is probably a plane or a special plane (UAV etc). I got my iPhone as didn't have my camera with me and I saw the most bizarre sighting of a craft I did not recognise, by its colour, shape or movement. It appeared and disappeared 6 times what we saw. It disappeared totally 3 times and 3 other times descended below our eye line.
The object flashed from green to red to bright blue to white to pink to purple.
It moved in strange motions from left to right and up and down and was also stationary, hovering.
