Tonight from London

At this latitude in summer, astronomical twilight may not end at all on the longest nights — a 'white night' that limits deep-sky observation. Polaris sits roughly at this latitude above the northern horizon, making it a permanent compass for navigation. The Big Dipper, Cassiopeia, and the northern circumpolar stars never set.
