The summer solstice and International SUN-Day will be commemorated on the rooftop of the Buffalo Museum of Science Sunday, the Buffalo Astronomical Association announced.

Visitors are invited to the museum from 11 a.m. to 3 p.m. Sunday to see the sun “live through specialized telescopes” of the astronomical association.

International SUN-Day is “a worldwide celebration of science outreach” and members of the astronomical association will share safe views through their filtered solar telescopes and provide some background information about how the sun works.

“You will be able to observe sunspots, arching prominences of hydrogen plasma and the intricate structures of the solar surface,” according to the association. “It is a rare up-close and personal look at our sun – an experience not to be missed.”

The event is suitable for all ages. It’s included with admission to the museum and is free for museum members.

The summer solstice, which launches us into the official season of summer, actually takes place at 6:51 a.m. Saturday. It’s the longest period of consecutive daylight the Northern Hemisphere will receive this year.
