Only three planets are visible this month; we start off with Venus. As soon as the Sun sets it is an easy to find shining at magnitude -4.4 in the south-west. By mid month it sets just before 9pm. Venus is almost a half crescent at the moment and it is easily noticed through binoculars.

Mars is a lot feinter than Venus at magnitude +0.9 and shines like a red star a little to the left of Venus. Not much detail is visible even through a telescope as it is such a small object.

Jupiter rises before 01:30 and shines at magnitude -1.8, brightening to -2.0 by the end of the month, in the constellation Virgo. It lies just above Spica, the brightest star in the constellation, which is outshone by the brightness of the king of the planets.

This month sees the Quadrantids meteor shower. It peaks on the 3rd but continues on until the 12th. The radiant, the point from which they appear lies close to he constellation Bo├Âtes.
