An astronomy event offered by the Klamath County Museum on Sunday, Sept. 17, will serve as a warm-up activity for next month’s annular eclipse that will be visible across Klamath County.

Sunday’s event will begin at 7:30 p.m. at the Klamath Falls YMCA, 1221 South Alameda.

The effect of “earthshine” on the dark side of the moon will be a key topic, said museum director Todd Kepple.

“We’ll be getting a good look at how light from the sun plays off the Earth and moon,” Kepple said. “Then next month, we’ll enjoy an alignment of all three bodies during the eclipse.”

Gatherings to view the annular eclipse on Saturday morning, Oct. 14, will be offered in Klamath Falls, Bly, Chiloquin and Gilchrist. Eclipse viewing glasses are available now at the Klamath County Museum.
