Noctilucent Clouds

On the morning of October 28^th,rare noctilucent clouds were visible over Monterey. Noctilucent clouds are thin silvery-blue cirrus-like clouds frequently seen during summer twilight conditions at high latitudes (above 50°) in both hemispheres. These clouds are primarily composed of ice crystals at heights 50-70 miles above the earth's surface.
