Redoubt - American Camp
San Juan Island NHP
"Light domes all around, Victoria brightest and largest. Class 4. Hazy, fog to the south, high humidity, seeing very good, transparency fair. Sky at 30 degrees altitude and lower much poorer than other parts, airglow cannot be discerned because of light domes and haze. No Zodiacal light, even in AM. Evening hours better, Cygnus milky way at Zenith well displayed but later the entire band looks washed out. Dark adaptation difficult. Port Angeles and Port Townsend visible in early evening, lost in fog late. Puget Sound light dome subdued, Victoria light dome bright but cut off vertically to the south, presumably because of fog. Data sets 1-3 OK, 4th has problem with wire pulling out of camera, no good. 5th incomplete and no good."

"Looking down on Victoria and Sidney B.C., Port Angeles in distance across the Strait. Daytime visibility 50 miles +, a little layered haze, no clouds. Low humidity, dry offshore flow. Some obstructions from trees to north and east, west and south pretty clear. Brightest core of light dome is Victoria, B.C., very significant, another light dome to the east smaller and farther away but has a bright core. Puget Sound area has broader, fainter light dome, NNE is a glow probably from Vancouver, core not seen because of trees. Bortle Class 4, ZLM 6.0-6.3 (seen very intermittently), 6.4 not seen. Transparency improves as it gets later (very good), seeing excellent. The Milky Way is washed out noticeably, but only slightly at the Zenith. Light dome of Victoria to at least 60 degrees altitude. Gradients throughout the sky, no region is uniformly dark. Milky Way disappears below Scutum, Sagittarius star cloud nearly invisible, lost in light dome of Victoria (at least 4 or 5 times brighter). Dark adaptation is not possible without shielding the eyes. Glare from hundreds of unshielded lights, brightest in the Sidney area 2 or 3 times brighter than Venus. However, at Zenith, the Cygnus Milky Way exhibits the North America nebula, rift in the star cloud, Great Rift visible throughout its entire length."
