Saturday 22nd (late) until dawn Sunday 23rd April - Lyrids Meteor Shower. The Lyrids are an average shower, usually producing about 20 meteors per hour at their peak. These meteors can produce bright dust trails that last for several seconds.
This year the shower peaks on April 22nd & 23rd, although some meteors can be visible from April 16th - 25th. Look for meteors radiating from the constellation of Lyra after midnight. The proximity to New Moon on the 26h April this year will help viewing.

Saturday 22nd April is also Earth Day, which is heralded as a pivotal opportunity for people, corporations and governments to join together to create a global green economy. It is hoped that coordinated efforts now will be recognized by future generations as a turning point. This is the 47th Anniversary of Earth Day, with the first Earth Day taking place in the USA on 22nd April 1970. It's often credited with initiating the modern environmental movement since it galvanised 20 million people (from all walks of life) into action. The Endangered Species Act, Clean Air Act, Clean Water Act plus multiple other innovative environmental laws followed soon after. Earth Day went worldwide twenty years later, rallying 200 million people from 141 separate countries and thrusting environmental concerns into the global arena.
