Significant brightening from Northern horizon to almost overhead ....
The aurora's also visible here in Kent, a greenish glow to the north. It's
the first time I've seen the "Northern Lights" from here, and only the
second time I've seen them at all (the first being from an aeroplane on the
way back from New York).

Leysdown, north Kent, 10m ASL.
