Local Observation Strategy

As a regional observation basecamp, Union City offers the essential amenities needed before heading into the isolated darkness of Houchin's Field. It marks the transition where the suburban light dome finally gives way to the true wilderness sky.

The Best Times for Stargazing in Union City

While Autumn offers the most consistent clear nights for Union City, wait for the 4-day window surrounding the New Moon each month for the deepest contrast. Since the sun sets early in the late Autumn months, you can often begin deep-sky imaging as early as 7 PM.

Expert Tips for Union City Observers

When observing from Riverside Regional Library, try to position yourself facing away from the nearest major light dome. For Union City residents, this usually means looking toward the rural horizons of TN to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Houchin's Field (167.8 miles away) remains the benchmark for regional sky quality.

Regional Perspective: Union City is situated just 12.5 miles from Martin, but its local horizon often provides a more stable viewing experience for planetary targets.

For observers in Union City, Houchin's Field serves as the definitive baseline for high-altitude transparency and localized skyglow data.

"Dewfall occurred during data collection, however dew heater prevented lens fog. Multiple light domes evident from site, as well as a continuous glow along horizon in all directions. Airglow was present. Andromeda galaxy easily visible, Beehive (Pegasus) visible with medium effort. Prominent dust lanes in Milky Way visible at zenith, but not below ~50 degrees."
