Sky Calendar works out every eclipse, meteor shower, aurora, ISS pass and dark Milky Way night for your city through 2076. Each event comes with local times, where to look and how high it will be, plus tonight's clouds and darkness at a glance and a reminder before it starts. Aurora nowcast, a map of dark observing spots, an AR sky finder and an astronomer mode with Bortle, SQM and red night vision.
