Teshikaga Night Sky Enjoyment Workshop
Thanks to your support, we have reached the 12th Teshikaga Night Sky Enjoyment Workshop. This year’s theme is the much-anticipated Geminids meteor shower. The program includes a classroom lecture and an observation session.
Why is Teshikaga’s night sky so stunning?
How should we protect and make the most of this night sky? What exactly is a meteor shower? What are tips for enjoying it? Which astronomical events should you watch for next year? This workshop is packed with answers and insights.
If the sky is clear, we will go outside and observe the meteor shower.
We hope you get to see bright meteors that can compete with the waning moonlight.
