Ruth and John Huss Observation Deck, Bell Museum
Free with gallery admission
Telescopes aren’t just for night observing. We’ll have a variety of our solar telescopes out on our observation deck for safe solar viewing as well as some hands-on interactive activities to better understand our nearest star, the Sun.
Solar Sundays are weather dependent—we need clear skies to see the Sun. If the weather does not allow for good viewing conditions, the activity will be canceled.
What you need
Dress for the weather, this includes sunscreen! It may be cold outside, but even then you can still get a sunburn. Always wear sunscreen when participating in outdoor activities.
Our telescope equipment utilizes safe Sun viewing methods; filtering the sunlight and projecting the sunlight.
Solar filters include white light filters that block 99.999 percent of incoming sunlight, safely allowing us to see any sunspots that might be visible.
H-alpha SolarMax II telescope filters out all the colors of sunlight except a specific red light (656nm) to allow us to see features such as solar prominences along the edge of the Sun.
Sunspotters use a different method to safely view the Sun. They utilize mirrors and lenses to project the Sun safely onto a screen (piece of paper). You can draw/trace your own Sun and sunspots to start our own solar data log.
