The night sky slowly changes over the course of the year, but with the exception of the planets and the Moon, these changes are quite slow, so even if you missed a video it should still prove useful for some time after it’s released. We hope you’ll take part in these challenges and we’d love to hear reports of your successes or any queries you may have. Just respond to the videos on BCO’s social media pages or email firstname.lastname@example.org.
The log of challenges to date is available here. Check back from 12.30 pm each weekday for the newest challenges.
