Clingmans Dome
Great Smoky Mountains NP
Local Relevance
The scientific findings at Clingmans Dome provide Jonesborough residents with the most reliable data on regional atmospheric stability.
"FWHM definitely affected, probably by vibrations of the observation tower itself. Light polltion sources visible both in foreground and at horizon. A thin layer of haze evident to east, possibly part of approaching clouds. First data set virtually cloud free. Sky free of contrails. Limiting magnitude found in Pegasus. Andromeda galaxy visible, M15 requires much effort. Milky Way detail easily detectable near zenith. Sky appeared noticeably brighter than previous nights, possibly due to some airglow. I also think it may have to do with the atmospheric clarity. All other nights contained some amount of possible light absorbing clouds."
