The Denver Museum of Nature and Science and the Denver Astronomical Society will be holding a “Solar Sunday” observing session this Sunday September 29 from 10am to 4pm on the Museum’s west patio (City Park side) weather permitting.
Several telescopes will be available to safely view the Sun in both white light and in hydrogen-alpha or H-alpha light. H-alpha telescopes view the Sun in a wavelength of light less than an angstrom or one ten billionth of a meter. The average piece of paper is one million angstroms thick.
White light telescopes lets one observe sunspots that were first viewed by Galileo centuries ago. H-alpha telescopes are specially designed for viewing flares and prominences on the Sun as they happen. We have seen some very impressive prominences come and go in past sessions.
Admission to the museum is not required, just show up on the west side of the museum. Members of the Denver Astronomical Society will be happy to answer any and all questions.
If you can’t make this session plan on joining the Denver Astronomy Society on Saturday October 12 at dusk at the University of Denver’s Historical Chamberlin Observatory to view the wonders of the night sky. The society will be celebrating Colorado Astronomy Day.
Wishing you clear skies
