There's a few of these around...some others at LHR I was looking a few months back but they only induced sleep.
There are web cams at Jersey and Guernsey but if you want to to miss anything, try not to blink.
With this one......I watched it earlier and saw nothing for about a minute until something drifted across too small to make out but I'm guessing it was an Airbus or a Boeing
