The above chalk sketch of the Sun, as seen by the Solar Dynamics Observatory, was produced by Luke Finnerty from Dublin (aged 11), who partook in Deirdre Kelleghan's (@skysketcher on Twitter) Rapid Rockets and Wicked Robots astronomy workshops in November. For his efforts, Luke has won the runner-up slot in our Frog Blog Science Week Art Competition. He wins a €25 iTunes Gift Voucher. Well done Luke! The winner was announced earlier this week as Rachel Rogers from St. Columba's College.
