July 1.

Good Morning, Evanston.

We have a new month, named for Julius Caesar. Before that, the Romans called it “Quintilis,” the fifth month.

Today will be another hot one.

Folks will be putting their parade-viewing chairs out at 6 a.m.

The National Weather Service reports the water temperature of Lake Michigan yesterday was 70 at the Chicago shore, 62 at the Chicago crib and 69 at the Wilmette buoy.

Those who did not celebrate the fourth annual International Asteroid Day yesterday can catch the end of the celebration may be able to stream the remainder of the 48-hourbroadcast from the Asteroid Day website or find something on Youtube.

Earthsky.org reports that International Asteroid Day, now recognized by the United Nations, “marks a global opportunity to raise awareness of the threat and opportunity posed by the numerous rocky bodies zooming through space.

Asteroid Day is held on the anniversary of the most devastating asteroid impact in Earth’s recent history – an event that took place on June 30, 1908, known as the Tunguska explosion, when a small asteroid struck the Earth over Tunguska, Siberia. It was originally estimated to have released the equivalent of up to 30 megatons of TNT, although, in recent years, the number has been revised downward to perhaps 3 to 5 megatons of TNT. Whatever the actual power of the explosion, it devastated an area of forest about 800 square miles (about 2,000 square km), the size of Greater London.”
