Local Relevance
For observers in Stonegate, Florissant Fossil Beds National Monument serves as the definitive baseline for high-altitude transparency and localized skyglow data.
"Very cold temps (27°) at start time and light winds. Transparency was excellent. The light dome of the greater Denver area easily visible to the NNE up to about 25° above horizon. Colorado Springs visible to the east and maybe a little brighter than Denver and light dome visible to the naked eye to almost 30°. The Milky Way rose later in the evening and the Prancing Horse was visible, though not vivid in detail, as the light dome of Colorado Springs was impacting that part of the sky. Naked eye limiting magnitude of 6.8 in the Big Dipper , which was near the zenith. Excellent night sky and great location for viewing and telescopes shielded from the highway."
