"Very clear night! Cloud free, but fire smoke visible to the south and east from N. Calofornia fires. Possibly some smoke to the north low along the horizon. No visible light domes in any direction and only one or two single glare sources in the valleys below from ranches. Exceptionally bright Milky Way with rich detail from Sagitarrius Star Cloud to Cygnus. Easily visble from horizon to horizon. M31 easily visble with naked eye. SQM readings probably a little low due to Milky Way being almost overhead. Milky Way casting shadows with no problem. One of the best nights skies this observer has seen."
