Space Weather involves the study of our sun and the effects it can cause on Earth. Activity from the sun can cause solar flares which can cause high levels of radiation in space. These effects can interrupt life on earth due to huge geomagnetic storms which can interrupt satellites, space missions, and the power industry. It is a fascinating topic with many areas for you to explore. You can find out how astronomers observe and record geomagnetic activities, and learn how to observe auroras (Northern Lights) in your area.
