"Try to find somewhere with a very low and clear south east horizon, as this will be the direction in which the moon will rise, and it will be in eclipse only while it is very low ( a few degrees above the horizon)."
Moonrise in London is about 21:13. I'm off to find a low and clear south-east horizon... (not that easy in London).
