SUNWHEEL GATHERING INFORMATION

Sunwheel in Winter


VERNAL EQUINOX 2014 -- SUNRISE & SUNSET GATHERINGS AT THE U.MASS. SUNWHEEL:

  • Thursday March 20, 2014
  • 6:45 a.m. and 6:00 p.m. (EDT)


The public is invited to witness the passing of the seasons by joining Dr. Judith Young of the U.Mass. Dept. of Astronomy to watch the Sun rise and set over the tall standing stones in the U.Mass. Sunwheel for the Vernal Equinox of 2014. The sunrise and sunset events will be held on Thursday March 20, 2014. Visitors for the sunrise viewing should arrive at 6:45 a.m., and visitors for the sunset viewing should arrive at 6:00 p.m. EDT. These gatherings will celebrate the Equniox and 17 years of Sunwheel seasonal events for the public, which have attracted over 10,000 visitors.

For those interested in learning about the sky, the gatherings will include a presentation which will describe the significance of the equinoxes & solstices, the cause of the seasons and phases of the Moon, the story of building the Sunwheel, and other calendar sites around the world such as Stonehenge & Callanish in the UK and Chichen Itza in Mexico. There will also be an explanation of the Moon's 18.6-year cycle, also called the Major Lunar Standstill. Come gather in community and connect with the sky -- bring your questions, your curiosity, and be prepared for freezing temperatures including waterproof footwear. The gatherings typically last 1 hour, and are held in all types of weather except rain and blizzards. Please note: The sunrise event will be more ceremonial and participatory in nature, including elements of ritual, personal reflection, poetry, song, and meditation, along with teachings on the astronomy of the seasons.

Donation: A $3 donation is requested to help with the cost of the additional sitework and future events which are planned. Sunwheel T-shirts & sweatshirts will also be available for purchase.

About the Vernal Equinox (in the Northen hemisphere):
This year, the precise instant of the Vernal Equinox, when the Sun is located in the sky directly over Earth's equator, is @ 12:57 p.m. EDT on March 20, 2014. The Vernal Equinox marks the first day of Spring in the northern hemisphere. It is also the day the Sun rises into the sky to be visible for 6 months as seen from the North pole, and the day the Sun disappears from view for 6 months (i.e. sets) as seen from the South pole. On the Equinox, any observer located on the Earth's equator will see the Sun pass directly overhead at local noon, and that person will cast no shadow at noon. For all observers on Earth (excluding the North and South poles), the Sun on the Equinox rises due East and sets due West, is up for 12 hours and down for 12 hours, illuminating all latitudes. Given that the Sun's position in the sky changes substantially from day to day at the time of the Equinox, only on the precise day of the Equinox are the above properties observed. From the Sunwheel here in Amherst, we observe a very beautiful sight as the Equinox Sun rises and sets through the stone portals in the Sunwheel toward the East and West directions.

Location: The UMass Sunwheel is located south of McGuirk Alumni Stadium, just off Rocky Hill Road. The Sunwheel can easily be reached from the center of Amherst, following Amity St. to the west, on the right hand side of the road about 1/4 mile after crossing University Drive.
