Boca Chita Key
Biscayne NP
"Extremely bright site, made even more so by the abundance (100's!) of campers/partyers who brought every conseivable form of light. Was able to shield most of the direct glare sources from the camera. Partly cloudy much of the night, but a short period of mostly clear skies. The light dome of the greataer Miami area overwhelming to the north and west. The sky to the east and southeast not too bad if you screen yourself from all the other light. The light dome extended to the zenith. Stars visible to the east at about 10°-15° above the horizon."
Boca Chita Key
Biscayne NP
"One of the brightest NPS sites this observer has ever visited. The continuous light dome from Homestead to Miami and north is impressive. The skies were partly cloudy initially, but slowly cleared to only a couple of some clouds. Limiting magnitude star of 6.8 (in Ursa Major) was only seen later in the night (0230) after at least 2 hours of observing time away from the light dome. Warm temperatures helped with visual acclimation. Most all of the local glare sources present the previous night were gone, which also helped the viewing. The entire landscape was well illuminated from the distant light dome."
