The Gardens at SIUE is a botanical garden in Madison County, Illinois. It sits roughly 3.4 km (2.1 mi) W of Edwardsville.
The Gardens at SIUE is a botanical garden on the campus of Southern Illinois University Edwardsville (SIUE). It originated as an arboretum and occupies a 35 acres (14 ha) tract of the university's 2,660 acres (1,080 ha) campus at Edwardsville, Illinois. It serves as a twofold function as a living laboratory dedicated in support of the educational and research missions of the university and as a place of beauty for the university community to share with the general public. In light of this duality, the gardens' master plan calls for the creation of a "public garden featuring spectacular horticulture, event spaces, areas for social gatherings and contemplative gardens" to be continuously enhanced over the coming years. The Gardens at SIUE was recognized by the Missouri Botanical Gardens as a "Signature Garden" until the MOBOT program was discontinued.From the Wikipedia article “The Gardens at SIUE”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From The Gardens at SIUE, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.2 hours on a moonless night), and the core peaks around 22° above the southern horizon. Our light-pollution model puts the sky at about Bortle 6 (bright suburban sky), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 6 Bortle 6 — Bright suburban sky. The Milky Way is only visible near the zenith; the sky glows grey-orange in photos. Modeled zenith brightness ≈ 19.15 mag/arcsec². Aurora needs roughly Kp 7.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 42% average cloud cover) and February as the cloudiest (64%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
