11th will see transit of Mercury (figure 1). Which means Mercury will pass in front of the Sun, casting a small black silhouette in front of the solar disk from 12:34 until 18:03 GMT (figure 2). This will be the first transit of Mercury since May 2016 and the last until November 2032. A typical transit lasts several hours.

For new observers, the most striking thing about the transit of Mercury is how small the planet appears in comparison to the Sun.
The simplest way to safely project the Sun is with a projector made from two pieces of card or paper. Good for viewing a solar eclipse or the transit of Mercury (figure 3). Mercury will be extremely small and may be difficult to see.

18th will deliver the Leonid meteor shower (figure 4). Active from 6th November to 30th November, producing peak rate of meteors on 18th. They will appear in the constellation of Leo. Visible from 22:25 each night, when the radiant rises above Eastern horizon. Remaining active until dawn, approximately 06:59.

18th will reveal the Pleiades (figure 5) open star cluster (M45 – NGC1432) in Taurus, well placed for observation. Visible in morning sky, accessible 17:31, when rising to altitude 12° above North Eastern horizon. Reach highest point in the sky at 00:17, 62° above Southern horizon. Becoming lost to dawn twilight, 06:45, 14° above Western horizon. M45 visible to the unaided eye, but better viewing through binoculars.
WARNING: Never attempt to view through binoculars, telescope or any optical aid an object near to the Sun. Also, never attempt to view the Sun unaided, doing so may result in immediate and permanent blindness. Always use astronomical approved viewing equipment.
The Stellarium software will assist greatly in locating objects in the sky.
