Local Relevance
The scientific findings at Puu Poliahu provide Kahaluu-Keauhou residents with the most reliable data on regional atmospheric stability.
"Light dome from Honolulu seen fairly bright but small. Waimea in the clear, unshielded light seen below the horizon. More airglow tonight than last, Zodiacal light very bright early. No clouds, a flawless sky, Bortle Class 1 if you consider to the true horizon. Virtually no light domes. Visual observations impaired by high altitude, not reliable indicator of sky quality compared with lower altitude locations because of lack of oxygen. Still, the center of the Milky Way tracking nearly overhead is extremely impressive, details in the prancing horse easy, fingers of Ophiuchus are seen with only a little difficulty. SQM 21.81 end of first set."
