Current Moon Phase and Illumination Details
Tonight’s moon phase in Chicago shows specific illumination percentages that determine how much of the lunar surface reflects sunlight back to Earth. This illumination percentage changes daily as the moon orbits our planet.
During waxing phases, the illuminated portion grows from right to left as viewed from the Northern Hemisphere. Chicago observers see the moon’s bright side expanding each night until reaching full illumination. Conversely, waning phases show decreasing illumination from right to left.
The moon’s current distance from Earth also affects its apparent size in Chicago’s sky. When the moon reaches perigee (closest approach), it appears about 14% larger than at apogee (farthest distance). This phenomenon creates supermoons when full moons coincide with perigee, offering spectacular viewing opportunities for Chicago residents.
Chicago’s urban light pollution affects moon visibility, but the lunar surface remains visible even downtown. The moon’s brightness overwhelms most city lights, making it one of the few astronomical objects easily observed from locations like Navy Pier, Millennium Park, or anywhere with a clear view of the sky.
Real-time moon phase tracking uses astronomical calculations based on the moon’s orbital position relative to the sun and Earth. These calculations provide Chicago-specific data accounting for the city’s geographic location and time zone.
Moonrise and Moonset Times for Chicago Tonight
Moonrise time in Chicago today varies based on the current lunar phase and time of year. The moon rises approximately 50 minutes later each day, creating shifting observation windows throughout the month.
During full moon phases, the moon rises around sunset and sets near sunrise, staying visible throughout the night. This timing makes full moons ideal for all-night observation sessions along Chicago’s lakefront. New moons, conversely, rise and set with the sun, remaining invisible in the daytime sky.
Chicago’s Central Time Zone (UTC-6 in winter, UTC-5 during daylight saving) determines exact moonrise and moonset calculations. The city’s position relative to the timezone meridian creates slight variations from other Central Time locations.
Optimal viewing conditions occur when the moon rises over Lake Michigan, creating spectacular reflections on the water’s surface. Popular Chicago viewing locations include Promontory Point, Montrose Beach, and the Adler Planetarium, all offering unobstructed eastern horizons.
Moonset times follow similar patterns, with the moon descending below the western horizon. Chicago’s skyline provides dramatic foreground elements for moonset photography, particularly when the lunar disk aligns with architectural features like Willis Tower or the John Hancock Center.
