Jupiter Tonight
Your area's forecast
Saves the forecast area nearest you so you can check its cloud again before the night.
When Jupiter is high in full darkness from your forecast area, what the Moon does then, and the cloud forecast for those hours.
Tonight's Jupiter calculation is unavailable for Chicago, IL. No viewing window is asserted.

About the opposition
NAOJ's 2027 almanac lists Jupiter opposition on February 11 at 09:29 JST, or 00:29 UTC. The instant is an astronomical marker, separate from a viewing window.
Fred Espenak's 2027 GMT almanac lists Jupiter at opposition on February 11 at a nominal 00:00 GMT (UTC). Its accuracy table states outer-planet opposition and conjunction times are accurate to ±3 hours. Sky Event Almanacs Courtesy of Fred Espenak, www.AstroPixels.com.
NASA's skywatching guide explains that Jupiter is opposite the Sun in our sky at opposition. Near then it is generally brighter and larger in appearance, up through the night and high around midnight. Check a local sky chart for your date and site.
NASA's Jupiter observing guide describes Jupiter as easy to find unaided. Binoculars may show some moons, and a small telescope can show its cloud bands and Galilean moons when conditions permit.
The U.S. Naval Observatory lists new Moon on February 6 at 15:56 UTC and first quarter on February 14 at 07:58 UTC. Phase alone gives neither local Moon timing nor observing conditions.
How this answer is calculated
The displayed area is a forecast-zone representative coordinate. Jupiter must be at least 15° above the ideal horizon while the Sun is at or below −18°. The window and Moon overlap use 30-minute samples, so their edges are approximate. Rise and set crossings are modelled between samples. Clouds are shown only at fresh forecast hours for the same area and night. Terrain, nearby lights, haze, fog, dew, optics and your eyes are outside this calculation. This page does not promise that Jupiter will be seen.
