I was working as a security guard on a building site near some farms in a somewhat rural area with many fields, wind turbines, etc. i was checking the area when i stopped to look at the night sky as in the uk we're currently having some very clear and awesome night skies. i've recently been on the lookout for those space-x satellites and other unrelated phenomena. on this particular night, i noticed a strange, star like object which seemed to be moving. there were plenty of other stars in the sky that night that were static as usual so this one stood out. it seemed to move towards the site from the south-east i believe. it then hovered and darted about in all directions like a firefly. that's when i started recording it. i recorded for a few minutes and then got back to work as i started to feel a bit lightheaded/disorientated.
