The Summer Solstice occurs at 9:38 AM PDST. "Sol" refers to the Sun and "stice" means to stand still. Each day before the Summer Solstice the Sun appears a little higher in the sky at noon. The Sunís altitude at Noon on the Summer Solstice, as seen from Sonoma County, is 75 degrees above the southern horizon. It also rises some 30 degrees North of East and sets some 30 degrees North of West. This results in the Sun being above the horizon for 14.5 hours and below for 9.5 hours giving Sonoma County its long warm summer days. After the Summer Solstice the Sun appears a little lower in the noon-day sky each day and rises & sets further South until the Winter solstice.

The Perseid meteor shower is estimated to peak around at 11:00 PM PDST this evening. It occurs this year only two days before a New Moon, meaning excellent viewing tonight and into tomorrow's early morning hours. Each year the Perseid meteor shower results from planet Earth crashing through the debris of comet 109P/Swift-Tuttle. As the small pieces of debris slam into Earthís upper atmosphere and burn up, they cause the atmosphere to fluoresce and we see a streaks of light called a meteors.

9/23/15

The Autumnal, or Fall Equinox, occurs at 1:21 AM PDST today. The Autumnal Equinox happens when the Sun passes through the Celestial Equator on its downward path toward the Winter Solstice. The Celestial Equator is the Earthís equator extended as a great circle out into space. Equinox refers to equal night. At the time of Equinox the Sun is essentially above and below the horizon an equal amount of time for all locations on planet Earth. The Autumnal, or Fall, Equinox marks the official beginning of our Fall season of the year. On the Autumnal Equinox in Sonoma County, at 12:00 Noon, you will find the Sun 52.5 degrees above the southern horizon.

9/27/15

The Full Moon occurs at 7:51PM PDST. Also occurring is the last of a series of four total lunar eclipses known as a tetrad of eclipses. The Moon will rise just after sunset already in the partial phases of the eclipse. Totality will begin about 7:11 with greatest eclipse at 7:48pm. In addition This Full Moon is also known as the Harvest Moon. It is the Full Moon that occurs closest to the Autumnal, or Fall Equinox. At this time of year the Moon has a low angle-of-ascent along the eastern horizon, as a result it appears to rise at nearly the same time each night. By doing so and being full, moonshine brightens the Earthís surface from twilight into the night hours for several days. This was said to allow harvesting of crops into the night hours; therefore, a Harvest Moon.

The Geminid Meteor shower is expected to peak around 10AM this morning. The Geminids often give a good show at least a day either side of their peak. This means the night of Sunday, December 13th and 14th (just a couple days after the New Moon) could offer a nice show, given clear weather conditions. The Geminid shower is not caused by the traditional debris of a comet's tail; but rather, from a frazzle Palladian type asteroid named "3200 Phaethon." The Geminid show has been increasing in numbers of meteors and could display over 100 per hour.

12/18/15

The First Quarter Moon occurs at 7:13AM PST.

12/21/15

The Winter Solstice occurs at 8:48 PM PST. "Sol" refers to the Sun and "stice" means to stand still. Each day before the Winter Solstice the Sun appears a little lower in the sky at noon. The Sunís altitude at Noon on the Winter Solstice, as seen from Sonoma County, is just 28 degrees above the southern horizon. After the Winter Solstice the Sun appears a little higher each day at noon. This results in increased daytime hours each day (until the Summer solstice) and is considered the beginning of the natural new year.

12/25/15

The Full Moon occurs at 3:11AM PST.
