Sky watchers at Sand Harbor for the Annular EclipseMay 20, 2012 was a very special day for local astronomers with an annular eclipse passing right through the Reno-Tahoe area. An annular eclipse is when the moon passes between the Sun and the Earth - blocking the Sun from view and creating an image of a "ring of fire". Dr. Paul Guttman and Space Science for Schools hosted an annular eclipse party at Sand Harbor Park. An enthusiastic group of 20 to 30 sky watchers of all ages turned out for the event that started with the beginning of the eclipse at 5:30PM.
Paul and the crew set up two telescopes for viewing: an Orion refractor with an Ha filter and a Coronado solar telescope. Both scopes provided outstanding (and safe) views of the sun and enabled the viewer to see the sun's spots and flares. Paul also set up a simple but effective "Solar Scope" consisting of a box with a reflective lens that clearly showed each step of the eclipse (see photo). Other participants set up telescopes with cameras as well as cameras on tripods - all protected by the appropriate filters. Viewers also used welding goggles, welding masks, plain square filters and simple solar glasses. While waiting for the full eclipse, Paul gave a mini-lecture on what to expect.
