Solar Observing

We’re taking advantage of the sunny summer weather and bringing our solar telescopes out each week this summer! Our expert staff will guide you through safe solar observing while teaching you about our closest star. Please note: that solar observing will be canceled in case of heavy clouds, rain, or dangerous temperatures. These decisions are made approximately 24 hours in advance. Solar safety 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 your own solar data log. Find additional solar observing dates at the Bell Museum Solar observing Solar Observing is an in-person event at the Bell Museum and is included in the cost of regular admission.
