Solar Observing
Observing the Sun is one of the most fascinating and dynamic forms of astronomy — but it must be done with extreme care. Unlike nighttime observing, solar viewing requires specialized equipment designed specifically for safely observing the Sun.
When done properly, solar observing reveals an ever-changing star filled with sunspots, prominences, filaments, and flares — features that can change over minutes or hours.
Safety Comes First
Looking at the Sun through a telescope without proper filtration can cause permanent eye damage in an instant. For this reason, solar observing should never be attempted with improvised or uncertified equipment.
All solar observing performed by our group uses purpose-built solar telescopes and filters designed to safely block harmful radiation.
Types of Solar Observing
White-Light Solar Observing
White-light observing shows the Sun much as it appears to the eye, revealing sunspots, faculae, and granulation on the solar surface.
These views allow observers to see sunspot groups evolve and track solar activity over time.
Hydrogen-Alpha (Hα) Solar Observing
Hydrogen-alpha observing reveals the Sun in a very narrow wavelength of red light, making visible dramatic features such as prominences, filaments, and surface activity that cannot be seen in white light.
These views often provide the most striking reactions during outreach events, showing that the Sun is an active and dynamic star rather than a static disk.
Solar Observing at Outreach Events
Solar observing allows us to bring astronomy to people during the day, expanding outreach opportunities beyond nighttime events.
Public solar viewing is especially effective at festivals, schools, science events, and community gatherings where daytime accessibility matters.
Our solar equipment is set up and supervised at all times to ensure a safe and engaging experience for everyone.
Why Solar Observing Matters
The Sun drives Earth’s climate, space weather, and the conditions that make life possible. Observing it helps connect people to the reality that we live next to a star — one that is constantly changing.
Seeing solar activity live, in real time, often becomes one of the most memorable experiences for first-time observers.
Solar observing reminds us that astronomy isn’t limited to the night — the universe is always above us.
