September 2010 Equinox is approaching

The September equinox occurs at 03:09 (or 3:09am) Coordinated Universal Time (UTC) on September 23, 2010. It is also referred to as the autumnal or fall equinox in the northern hemisphere, as well as the spring or vernal equinox in the southern hemisphere (not to be confused with the March equinox). This is due to the seasonal contrasts between both hemispheres throughout the year. The equinox will occur in the evening of September 22, 2010, for locations on US Eastern Daylight Time or further west. To find the September equinox date in other time zones or other years, please use the Seasons Calculator. What happens during the September equinox? The sun crosses the celestial equator and moves southward in the northern hemisphere during the September equinox. The location on the earth where the sun is directly overhead at solar noon is known as the subsolar point. The subsolar point occurs on the equator during the September equinox and March equinox. At that time, the earth’s axis of rotation is perpendicular to the line connecting the centers of the earth and the sun. This is the time when many people believe that the earth experiences 12 hours of day and night. However, this is not exactly the case. During the equinox, the length of night and day across the world is nearly, but not entirely, equal. This is because the day is slightly longer in places that are further away from the equator, and because the sun takes longer to rise and set in these locations. Furthermore, the sun takes longer to rise and set farther from the equator because it does not set straight down – it moves in a horizontal direction. Moreover, there is an atmospheric refraction that causes the sun’s disk to appear higher in the sky than it would if earth had no atmosphere. has a more detailed explanation on this topic. has more information on why day and night are not exactly of equal length during the equinoxes.

In his Newsletter Sal Rachele from Sedona, AZ writes: “Once again, it’s that special time of year when the days and nights are of equal length. It is also the time of most rapid change in the Earth’s seasonal cycle, which can be likened to the middle point of a pendulum swing (the base point). Coupled with the equinox is a full moon and Jupiter conjunction, for a triple treat. Astrological and astronomical events do not, in themselves, cause our states of consciousness, but they can greatly augment what we are already feeling. During a time of amplified energy, it’s a good idea to send loving and compassionate thoughts to those places and situations that seem to be out of balance. Let’s also resolve to heal any conflict within ourselves that could add to the problems in the world.”
