Solar Thursdays back at the RBG

By Mario Carr

If the rings of Saturn blew you away when you first looked though a telescope, just wait until you see the Sun.

Every second for the last 4.5 billion years, the Sun has been radiating millions of watts of life sustaining energy. Without it, we wouldn’t be here.

The Sun is a fascinating celestial object converting hydrogen to energy and is a model of how other stars in the universe work. If you would like to see solar flares, sunspots and other features on the Sun, the Royal Botanical Gardens (RBG) has brought back Solar Thursdays for another summer.

Once a week from noon to 1 p.m., special equipment that filters out the harmful bright light of the Sun will be set-up on the front lawn of the RBG headquarters at 680 Plains Road West, Burlington so everyone can see close-up views of our nearest star.

The event is free but may be cancelled due to poor weather conditions. If you plan to attend, contact Dr. David Galbraith at 905-527-1158 for updates.

Warning. Never look at the Sun unless you have special equipment since it’s light could cause permanent eye damage or blindness.

Here are July stargazer events. Most are listed in the Hamilton Amateur Astronomers calendar.
