Atmospheric Ice-crystal Effects Are Often Observed, starting about this time of year, because of the frequent appearance of high clouds made of tiny bits of ice. The most familiar of these optical effects is the 22°-radius halo, or ring, around the sun or the moon. Less often seen: a “corona,” a colored disk around the sun or moon — not the same as the solar corona seen during total eclipse; a “sundog,” a colored arc left and right of the sun; the sun pillar, a vertical column of light above the rising or setting sun; and a host of other rare and inconspicuous optical phenomena. All of these optical effects are a consequence of sunlight or moonlight refracting through or reflecting from the tiny facets of ice crystals in cirrus and other types of high clouds.
The Fremont Cottonwoods along The San Diego River in Mission Gorge are still showing their best tawny foliage. You can park at the Old Mission Dam historic site or at the Mission Trails Regional Park visitors’ center and explore the riparian area by way of riverside trails, or by walking, bike riding, or skating along the bike path high above the river’s south and east banks. Large cottonwoods can also be seen along other watercourses throughout the San Diego County backcountry, including along the Sweetwater River near Cottonwood Golf Course, and in Cottonwood Valley, east of Pine Valley along Interstate 8.
Saturdays New Moon Will Provide Us With Higher Than Average Tides. Saturday’s high tide will be 6.5 feet at 7:56 am, Sunday’s will be even higher at 6.56 feet at 8:24 am, and Monday’s high tide will peak at 6.59 feet at 8:55 am. We shouldn’t see any coastal flooding since the surf is predicted to only be in the 2-3 foot range, but it is always fun to go down and check out the waves crashing against the rocks.
