Time was 18.25 not 17.25
Noticed at high altitude, at first i thought it was a bird riding on thermals. heading in general direction towards the Olympic park.
At first appered black, it moved slow, the stopped for a brief moment, changed colour to silver/white, also flashed red. Then it moved on not at any great speed. Over the heathrow flight path, a plane was on approach at a lower altitude.
It was to high for an decent picture.
Please advise if reported by anyone else, as i have studded the subject for some yrs
