"Seeing good, transparency poor, very hazy. Lights from San Joaqin Valley cities subdued by haze and smoke, gradually clearing but very slowly as night progresses. Stars near the horizon almost extinguished, overhead pretty good sky, fairly dark. Airglow low plus extinction gives a very dark horizon sky to the northeast. SQM 21.66 1st, 21.74 2nd, 21.74 third, 21.76 fourth."

"Evening begins very hazy, lots of moisture in the air. As night progresses, inversion layer drops below summit, downvalley wind brings clearer and drier air. Lights of cities to west somewhat dimmed by haze, however illuminate the summit on its west side strongly, ruining night vision unless hidden from view. Air very steady, faint stars easily seen near zenith. Western sky very bright to 45 degrees above the horizon. M33 barely visible near zenith, gegenschein barely visible near midnight. Fantastic seeing, excellent observing site for that reason alone. However, do not recommend the summit for public or telescopes, possibly Wolverton parking lot or Wuksachi?"
