On this night, June 3, 2017, the planet Jupiter is very apparent in the sky, only a few degrees from the Moon.
Another Jupiter directly clashed with London Bridge. On June 13, 1984, as the HMS Jupiter was leaving the Pool of London after a visit to the capital, she collided with London Bridge causing significant damage to both ship and bridge. The ship's Captain, Commander Colin Hamilton, was later court martialed at Portsmouth on December 4, 1984.

• Jupiter is the bright "star" with the Moon, as seen at right. They're only a couple degrees apart as viewed at dusk from North America. But Jupiter this evening is 1,860 times farther away.
• Lower left of them is Spica. Much closer to them in the opposite direction is fainter Gamma (γ) Virginis, a close double star for telescopes (separation 2.6 arcseconds this year).
• And, a double shadow-transit occurs on Jupiter tonight. From 10:22 p.m. to 12:22 a.m. EDT, both Io and larger Ganymede are casting their tiny black shadows onto Jupiter's face.
• And then, Jupiter's Great Red Spot transits the planet's central meridian around 12:55 a.m. EDT (9:55 p.m. PDT). Quite a telescopic night for this little group of objects.
London Bridge is usually rather calm. On February 28, 1992, a bomb exploded at London Bridge station injuring 29 people.
On June 3, 1982, the Israeli Ambassador to the Court of St. James's, Shlomo Argov, was shot outside the Dorchester Hotel by three gunmen from the Abu Nidal group. The ambassador survived a three-month coma, but was paralysed and required constant medical attention until his death in 2003 as a result of the wounds. See other "Terrorist Incidents in London" here.
