Tonight is the biggest meteor shower of the year, the Perseids. In Spanish, they’re called the tears of St Lawrence, because St Lawrence’s day is the 10th. Astrotour will be at La Polvacera basketball court. From 8 – 9 pm they’ll hold workshops and from 9pm to 11:30, observation with telescopes. If there’s low cloud, you’ll get a better view up at one of the astronomical viewpoints.
