A Strawberry Moon and the Latest Sunset of 2010
June's Full Moon, which occurs on the evening of Friday, June 25 through the morning of Saturday, June 26, is sometimes called the "rose moon," "strawberry moon," or "honey moon" because of its tinted color. Especially when seen from the high northern latitudes, the June full moon always stays close to the horizon, where its light is filtered and reddened by the atmosphere. From San Diego, June's full moon reaches a maximum altitude of about 33° above the horizon -- about as high as the sun gets at noon in December.
2010's June Full Moon will experience a partial lunar eclipse, during which the moon partly enters the Earth's shadow, and therefore looks as if it has a bite taken out of it. The event occurs during the wee hours of Saturday, June 26. Partial eclipse starts at 3:17am, and continues until after the moon sets at around 5:45am. At mid-eclipse, 4:38am, slightly over half of the moon will be covered by Earth's shadow. This event will likely not be observable from the coastal areas of San Diego, due to the usual coverage by late-night and early morning, marine-layer clouds. The skies should be clear inland, especially over San Diego County's mountain and desert regions.
Latest Sunset of the year, 8pm Pacific Daylight Time in San Diego, occurs this Sunday, June 27 -- approximately one week after the summer solstice (our longest day). From now until late July there will be little change in the time of sunset, even though the total length of daylight will steadily shorten.
Grunion Runs are predicted to occur during the late evening hours (generally after 10pm and before 1am), following the nocturnal high tide, June 26 through June 29. The small, silvery grunion tend to spawn on wide, gently sloping beaches such as Silver Strand, Mission Beach, Pacific Beach, La Jolla Shores, and Del Mar. Open season for grunion starts in June, and from then until the end of summer, the fish can be collected in reasonable numbers using the hands only (fishing licence needed for persons 16 years of age and older).
