Chasing Shadows: A Guide to Eclipses Visible from Chicago
The dance between the Sun, Moon, and Earth can create awe-inspiring astronomical phenomena, with eclipses being some of the most captivating. This guide delves into the different types of eclipses observable from Chicago, Illinois, and equips you with the knowledge to predict and witness these celestial events.
Unveiling the Mystery: Types of Eclipses
There are two primary types of eclipses: solar and lunar.
-
Solar Eclipse: A solar eclipse occurs when the Moon passes directly between the Sun and Earth, casting a shadow on a portion of Earth’s surface. Observers within the path of totality will experience a complete blackout of the Sun for a brief period. Locations outside the path of totality will witness a partial eclipse, where the Sun appears partially covered by the Moon.
-
Lunar Eclipse: A lunar eclipse occurs when the Earth casts its shadow on the Moon. This happens when the Sun, Earth, and Moon align in a nearly straight line. During a total lunar eclipse, the Moon will be completely engulfed in Earth’s shadow, taking on a reddish hue due to sunlight filtering through Earth’s atmosphere. Partial lunar eclipses occur when only a part of the Moon falls within Earth’s shadow.
A Glimpse into the Future: Upcoming Eclipses in Chicago
Predicting eclipses is a well-established science, allowing us to anticipate these celestial events well in advance. Here’s a look at some upcoming eclipses visible from Chicago:
-
September 18, 2024: A partial lunar eclipse will be visible from Chicago. During this event, a portion of the Moon will be obscured by Earth’s shadow.
-
March 14, 2025: This will be a total lunar eclipse, offering skywatchers in Chicago the opportunity to witness the Moon completely immersed in Earth’s shadow.
Table: Upcoming Eclipses Visible from Chicago
| Date | Eclipse Type | Description |
|---|---|---|
| September 18, 2024 | Partial Lunar | A portion of the Moon will be covered by Earth’s shadow. |

Gearing Up for the Show: Essential Preparations
-
Research the Eclipse: Once you’ve identified an upcoming eclipse, gather details about the specific type (solar or lunar) and the percentage of the Sun or Moon that will be obscured (for partial eclipses). This information will help you determine the level of visibility and any necessary precautions.
-
Prime Location Selection: Light pollution can significantly hinder your eclipse viewing experience. If you’re targeting a solar eclipse, look for an open area with an unobstructed view of the horizon, preferably away from tall buildings and streetlights. For lunar eclipses, light pollution is less of a concern, but a location with a clear view of the night sky is still ideal.
-
Safety First: Solar eclipses demand extreme caution. Never look directly at the Sun, even during a partial eclipse. Special solar eclipse glasses with certified ISO filters are the only safe way to view the partially eclipsed Sun. Looking at the Sun without proper filtration can cause permanent eye damage, including blindness. Lunar eclipses, on the other hand, are safe to view directly or with binoculars.
-
Weather Watch: Keep an eye on the weather forecast leading up to the eclipse. Cloud cover can significantly obstruct your view, so having a backup plan or alternative location in mind is helpful.
-
Embrace the Experience: Eclipses are a shared human experience. Consider attending a public viewing event hosted by astronomy clubs or universities. These events often provide telescopes with solar filters for safe solar eclipse viewing and offer valuable insights from astronomy experts.
Capturing the Moment: Photography Tips for Eclipses
If you’re interested in capturing the eclipse photographically, here are some essential tips:
-
Camera and Lens: A DSLR or mirrorless camera with a telephoto lens is ideal for capturing the eclipse in detail. A tripod is crucial for maintaining camera stability during long exposures.
-
Solar Filter Photography (Solar Eclipse Only): For a solar eclipse, a special solar filter specifically designed for astrophotography must be attached to your camera lens. Improvised filters or using your regular solar eclipse glasses are not safe for your camera sensor.
-
Manual Settings: Switch your camera to manual mode and adjust the shutter speed, aperture, and ISO settings to achieve the desired exposure. Experiment with different settings beforehand to find the optimal combination.
-
Focus and Timing: Pre-focus your camera on a bright object like the Moon (for a lunar eclipse) and lock the focus. For solar eclipses, ensure the solar filter is properly attached before focusing. During the eclipse, use a remote shutter release to minimize camera shake when capturing the image.
