This is not the first time I have seen these orange lights in the sky. I have seen them prob about 4 times. This is the second time I have taken pics of them. They are very large and this time I could see one had a huge orange aura around it. There are no blinking lights or sounds. The first time I saw one it was late at night, the second time they were in a formation of 3 and then one, next time was only one and this time there were two, but not close together. They fly with direction and purpose, they do not fly in a circle, just straight off and then dissapear, fade away. This time I had my camera ready, my friend said that she thought they were square, but I could not make out the shape. I do not know what they are, but they are very bright. I live in the UK, Essex.
