View solar extremes at Beaman.
West Boylston astronomer David Snay will set up his solar telescope on the front lawn of the library, 8 Newton St., for public viewing from 11 a.m. to 2 p.m. Tuesday. The rain and "cloud" date, which also means overcast skies, is Thursday, Aug. 9.
Snay, a member of the Aldrich Astronomical Society and the Charlie Bates Solar Astronomy Project, said the sun has an 11-year cycle in between periods of high and low activity, he explained.
The sun is just beginning a period of high activity, called the solar maximus phase, which may make solar flares and sunspots visible through the telescope.
Snay's telescope, a Lunt 60 mm. hydrogen-alpha telescope at 32x magnification, is specifically designed for viewing the sun safely. He cautioned that people could damage their eyes if they look directly at the sun with ordinary telescopes or binoculars.
Free solar viewing glasses are available for each participant at the event.
More information about this event will be posted on the Beaman Memorial Library's Facebook page.
