After the first successful edition in 2007, OAB and the Council for Culture of the Province of Bologna decided to organize, on 8 June 2008, the second edition of the ``Sun-day" in the Villa Smeraldi Park, a beautiful park near Bologna, with a Solar System exhibition, lectures, projections, solar telescopes, an educational laboratory for primary-school students, a musical show, and a laser tour of the sky in the evening. Thanks also to the fine weather conditions on that Sunday, more than 500 people and children attended the event.
