Sentinel Dome
Yosemite NP
Local Relevance
The scientific findings at Sentinel Dome provide Riverbank residents with the most reliable data on regional atmospheric stability.
"Very clear, steady, excellent night for Astronomy. Light domes brighter from valley cities than on 8/31/2005, presumably because of clearer air. Gegenschein not visible. Some smoke below summit, should not interfere. No clouds. Sky near zenith very dark, excellent detail in Milky Way, to south and west significantly degraded."
Sentinel Dome
Yosemite NP
Local Relevance
The scientific findings at Sentinel Dome provide Riverbank residents with the most reliable data on regional atmospheric stability.
"Monitoring site at summit, just south of monument showing peaks. Very good sky considering proximity to Fresno, brightest light dome. Broad glow to distant WNW, Sacramento/San Francisco? All light domes do not extend much more than 20 degrees above horizon, may be hazy in the valley damping sources. Gegenschein not visible. Air quite steady, revealing fainter stars. Fire smoke to southeast. No clouds. This data simultaneous with C Moore at Pothole Dome."
