- STEP 3. Local Support: Contact SIU Carbondale Physics Department for updated site access and group observation schedules.
- STEP 4. Observation Density: There are 5 recognized sites near Poplar Bluff offering varied horizons and atmospheric stability levels.
Poplar Bluff is positioned in a strategic 'Starlight Corridor.' It is far enough from the MO metro glare to allow for deep-sky imaging, yet serves as a convenient staging area for the deeper Class 4 skies found at Houchin's Field.
The Best Times for Stargazing in Poplar Bluff
In MO, the transitional periods of early Summer often provide a stable atmosphere between weather fronts. For Poplar Bluff residents, this means less 'star twinkling' (scintillation) and a significantly steadier view for high-magnification planetary observation.
Expert Tips for Poplar Bluff Observers
Thermal equilibrium is key. Since Poplar Bluff temperatures can shift rapidly after sunset, allow your telescope mirrors at least 45 minutes to 'cool down' before attempting high-magnification work at Sam A. Baker/Otahki Lake KOA. This prevents 'tube currents' from blurring your view of Jupiter or Saturn. Scientific Context: While local conditions vary, the instrumented reading of Bortle 4 at Houchin's Field (237.0 miles away) remains the benchmark for regional sky quality.

Houchin's Field
Mammoth Cave NP
Local Relevance
The scientific findings at Houchin's Field provide Poplar Bluff residents with the most reliable data on regional atmospheric stability.
"A very calm, humid and clear night. 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. Limiting magnitude found in Pegasus."
Log Cabins
Fort Donelson NB
Local Relevance
For observers in Poplar Bluff, Log Cabins serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"SQM of 20.47 at 2035 local time. Only fair transparency and seeing. Some fast moving clouds. High humidity. Milky Way visible from 20 degrees above north horizon. Great rift visible, Saggitarius cloud not easily visible, Scutum cloud not visible. Milky Way about 10-12 degrees wide, but faint and no fine details. To the NW a blue white light dome easily seen. Due East is the Clarksville lightdome almost 25 degrees high and 15 degrees wide. Core is bright. Adjacent to the light dome is a spotlight (which we determined was coming from the cemetary here in FODO park). To the West and Southwest is another lightdome fainter than Clarksville, but brighter than the Milky Way"
