SunDay: Observing the Sun with the World’s Largest Solar Telescope

When:  Apr 25, 2021 from 17:00 to 19:00 (UTC)
In celebration of Global Astronomy Month's annual SunDay join our guest speakers Claire Raftery and John Williams from the National Solar Observatory in Boulder, Colorado as they delve into the details from the worlds highest resolution image of the Sun. The Inouye Solar Telescope is the worlds largest, and is set to start operations later this year.  They  will discuss the challenges of focusing a 4-meter solar telescope, and review different solar features and how best to observe them from home.
