In the direction of the constellation Aquarius. The shower is named after the brightest star of the constellation, Eta Aquarii. The Eta Aquarids is one of two meteor showers created by debris from Comet Halley. The Earth passes through Halley's path around the Sun a second time in October. This creates the Orionid meteor shower, which peaks around October 21.
Observing conditions are not great from Northern Hemisphere. From the UK, the radiant will only climb 15 degrees above the horizon by 4 AM. The Moon should not interfere too much, but it should be a very memorable morning, especially with Jupiter and Saturn complimenting the scene.
Comet Halley takes about 76 years to orbit the Sun once and is currently out around the orbit of Neptune and almost at its farthest distance away from the Earth before making a turn and heading back in our direction.
