The total lunar eclipse two weeks ago required getting up early in the morning and trying to find the moon through trees and Chicago street lights. Late this afternoon, Chicago (and most of North America to the west) will get a much better show from the moon as it partially obscures the sun.
Starting around 16:35 CDT this afternoon, the moon will creep in front of the sun, reaching maximum eclipse right at sunset (17:59 CDT).
Of course, this being Chicago, and despite the crystal-clear blue skies above the city right now, the forecast for this afternoon calls for increasing clouds and showers. Because we won't actually see the eclipse, that just means it will get dark and gloomy an hour before sunset.
And look at that sunset time. That's right, last night was the first sunset since March 8th to occur before 6pm.
Ah, well. If you live west of Chicago, you'll get a good show from the moon this afternoon, with less gloom and more astronomical coolness. Enjoy.
