My husband is interested in the period of the year knowing when the sun reaches at least 45 degrees above the horizon. When will that take place?
Deborah and Neil Levin
Dear Deborah and Neil,
The noon sun in Chicago finally will reach an elevation 45 degrees above the horizon, the halfway point between the horizon and the zenith, on Friday.
Over the course of the year the highest daily sun elevation varies from a low point of 24.7 degrees on the winter solstice to a peak of 71.6 degrees on the summer solstice.
At 11:51 a.m. Friday, the sun will be at an elevation of 45 degrees and remain there for about 21 minutes. At 12:02 p.m. Sept. 30, the peak sun elevation will drop below 45 degrees and not regain that 45-degree peak until 11:36 a.m. March 13, 2011.
Professional photographer John Smierciak from St. John, Indiana sent us this striking picture of the Thursday’s thunderstorm. John tells us this view is looking west towards Illinois.
Thanks for the great shot John!
Shortly before 9:15 p.m. radar indicated a pronounced weakening in the thunderstorm activity that have been moving through the Chicago area. The thunderstorms should continue to weaken and they move north into Lake County and Lake Michigan.
Late reports indicate pea-sized hail at Melrose Park shortly after 8:35 p.m, near O’Hare Airport near the intersection of Harlem Avenue and Northwest Highway and in Morton Grove.
Janet sent us this shot of Navy Pier at sunset. She tells us:
“Interesting cloud formations and sunset.. changed every minute. Took this photo tonight. hope you enjoy”
We certainly do enjoy it Janet, thanks!
