Mysterious lights over North Wales

What was the name of the SR-71's replacement? Aurora? From the Daily Post of Wales:

MYSTERIOUS lights appearing in the night sky over North Wales were baffling experts last night. Former DIY store manager John White is seeking answers after catching sight of the strange lights near his rural home. He took nine hours video footage of the lights near his house in Llannefydd, near Denbigh, over the past five weeks. But Ministry of Defence chiefs have so far failed to come up with an explanation.
