A second sky-light gnomon creates a classical analemma on the floor.

He has a number of videos well worth watching:  Sunset at the foot of the pyramid of Pueblito, Mexico, diurnal beams at summer and winter solstices, the equinox and more.  Visit Ruben Nohuitol’s photos and web-cam videos at: www.ruben.mx

Posted: Saturday, 21 January 2012 16:15

nass_news_2012_jan_downton_abbeyMany have been following the Primetime Emmy Award winning series Downton Abbey on PBS.  This British World War I period drama was filmed on location at Highclere Castle in Hampshire, which represents the fictional Downton Abbey.  Many outdoor scenes were filmed in the village of Bampton, Oxfordshire. (See http://en.wikipedia.org/wiki/Downton_Abbey )

As you follow the lives of aristocrats and servants in this acclaimed series, keep an eye out for sundials.  Attached are photos of three sundials noticed by NASS members.  Want to search for yourself?  The full episodes of series #1 are available at PBS.org and the new series #2 is just starting.

Chatham Square Dial Vandalized - Again Print
Posted: Friday, 20 January 2012 22:15

nass_news_2012_jan_catham_square_dialLesley Conn reports in the Savannah Morning News the restoration of its vandalized sundial.  This is no college prank, but a malicious and repetitive attack on the Louis B. Toomer sundial in Chatham Square in the historic district of Savannah, Georgia. Conn reports that “City officials are adding new elements to the repair process – a public plea for help and a reminder to the monument marauder that destruction of public property is a felony. They made their case Tuesday after sealing a new sundial to the stone base.”

The 8 inch diameter sundial has a face of bronze with Roman numeral hours delineated every 15 minutes and delicately shaped brass gnomon.  It sits atop a concrete pedestal with indented lettering stating “In Memory of Louis Burke Toomer, Registrar of U.S. Treasury, 1953-1956, Founder and President of Carver State Bank, 1927-1961”. ...”   If the vandalism is a demonstration of “occupy wall street” it is very misplaced.  City conservation coordinator Larry Fagley says “We’ve welded it, we’ve drilled holes in it to shoot more epoxy into it, and within a week, they’ve kicked it off…”

nass_news_2011_dec_UWashSundial

Want to watch a sundial in action?  Professor Woodruff Sullivan and Ian Smith at the University of Washington in Seattle have just launched an active webcam of the University’s large vertical declining sundial on the side of the Physics and Astronomy building.   The webcam image is updated once per minute day and night. “we know that some of you will want to stare at it for hours on end (or at least bookmark it….”

Their website has many features including the first two time-lapse movies of the giant sundial showing the all-day shadow on the summer solstice and on the autumn equinox. More time lapse videos will be presented during the months that come.  In the near future they will improve the present camera with higher-resolution and greater reliability.

A flurry of sundial webcams existed in 2004-05 when the EarthDial Project, the invention of Bill Nye and Woody Sullivan, was run under the auspices of The Planetary Society. The Project, with a motto Two Worlds, One Sun was run in conjunction with the MarsDial Project, which involved the Mars Exploration Rovers Spirit and Opportunity, each of which landed on Mars in 2004 with a small calibration target turned into a Mars sundial on its deck. People around the world were urged to build sundials of a standard design and display them to the world using a webcam. Click Here to See Time Lapse Movies of Some of These Dials.  A new Mars sundial will arrive red at the red planet next August onboard Curiosity.

Dial "Down Under" Acquired by Historical Museum Print
Posted: Monday, 05 December 2011 06:43
nass_news_2011_dec_cohen_2nass_news_2011_dec_cohen_1The words “sundial” and “convict” are not often used in the same context, but that is the situation in Port Macquarie, Australia when a vintage sundial made around 1840 was put on permanent display at the Port Macquarie Historical Museum.  The dial was made by colonial engraver Raphael Clint and was once owned by Danial Cohen, who, convicted in 1830 of receiving stolen property in Lancaster, was sent to Port Macquarie, a penal colony at the time.

Hour Horary Quadrant Print
Posted: Sunday, 04 December 2011 16:19

nass_news_2011_dec_1396_quadrant1What’s worth more than £150,000?  An hour horary quadrant dating to 1396 with the personal seal of Richard II.  It is up for auction at Bonham.  The quadrant, owned by Christopher Becker in Australia, spent the last twenty years in a bag of pipe fittings.  An ancestor of Becker apparently came across the quadrant 150 years ago somewhere in Northern England before its final resting spot in Australia.

This quadrant divides the day into 24 equal hours.  With a plumb-line attached to one of its corners, pointing the quadrant towards the sun allows the time to be read at the intersection of the plumb line and one of the engraved scales.  On its reverse, the quadrant shows a badge depicting a stag lying down wearing a coronet around its throat,  symbols associated with Richard II.

The oldest European astrolabe dated 1326 is credited to being used by Chaucer (1342-1400) and resides in the British Museum.

Curiosity Sundial Launched Print
Posted: Saturday, 03 December 2011 19:35

nass_news_2011_dec_CuriosityDial“Two Worlds One Sun” lives on as the Mars Science Lander called Curiosity makes its way to Mars, once again carrying a camera color calibration target that will be used as a sundial.  The original Mars sundial was the idea of Bill Nye, the Science Guy, and designed by Professor Woody Sullivan of University of Washington.

The spacecraft was launched toward Mars on 26 Nov 2011.  Onboard Curiosity the camera calibration sundial has four edges each containing a panel of text and image, written by Jim Bell, planetary scientist from Arizona State University and the Mars Exploration Rover team with graphics designed by artist Jon Lomberg. 

The digital camera and calibration target was created by Tyler Nordgren from the University of Redlands and a group of six scientists, astronomers, educators and artists worked together to create a digital camera that is calibrated to photograph the climate on Mars.  On the team was Bill Nye and Professor Sullivan.

Dr. Bell now executive Director of the Planetary Society and Lomberg were both on the team that designed the similar sundials for the the Spirit and Opportunity Martian rovers.  Artist Jon Lomberg has a long history in spacecraft graphics, starting with Design Director for  NASA’s Voyager Golden Record and a long-time collaborator of Carl Sagan. He won an Emmy Award for his work as Chief Artist of the TV series COSMOS.

Connetquot Students Use Sundials to Tell Time Print
Posted: Wednesday, 16 November 2011 09:13

nass_news_2011_nov_ConnetquotSecond-grade students at Connetquot Elementary School in Islip, New York, created sundials using paper plates and pencils.   The pencil gnomons were set mostly vertical by the students and then they traced the resulting shadows at three times during the day.  This helped teachers Leslie Davis and Melissa Love demonstrate the sun’s apparent movement in the sky and talk about the earth's rotation as the cause. "The students really had fun," said Love, "and they were able to recognize that a sundial is a tool that can be used to measure time."   See more photos at: http://www.eischools.org/news.cfm?story=31664&school=293

Italian Gnomonist Giacomo Agnelli Dies Print
Posted: Saturday, 05 November 2011 17:30

Dear Friends,

A great loss has hit our gnomonic community in Italy. Our friend Giacomo Agnelli died about a week ago.  Giacomo was one of the great gnomonists of the past. He had written dozens of articles in engineering and horology, also dealing with mechatronics [mechanical] sundials. He had worked at the European space project, and had frequent ...articles for our magazines [on] gnomonics. He had participated in all meetings of horology in Italy and was known for his satirical cartoons and caricatures gnomonic...

Washington's Sundial in the Spotlight Print
Posted: Saturday, 15 October 2011 18:03
nass_news_2011_oct_mount_vernonGeorge Washington's Sundial is in the Spotlight: Sometime during 1765-1781 Washington placed a 12 inch brass horizontal sundial at the heart of his Mount Vernon plantation. The sundial sits atop a white painted octagon wood pedestal in the center of the front lawn of his mansion.  It stands as a visual reminder of the importance of time to all who passed it.  A replica of the original dial now reminds tourists of the time, but the original is in the museum.  Go to http://www.georgewashingtonwired.org/ and read more about Mount Vernon and visit NASS_Registry_Dial167 where you can find details of Washington’s dial.

Sun City Dial Re-Dedicated Print
Posted: Tuesday, 11 October 2011 19:55

nass_news_2011_oct_SunCityThe restored Sun City dial re-dedication ceremony held October 7th, 2011 was a huge success.  A large crowd of several hundred dial enthusiasts came to the grounds of the large dial at the Sundial Recreation Center at 8:30 in the morning to celebrate the restoration of the dial that months before was an endangered and condemned landmark. 

The dial was the idea of John Meeker, Sun City developer.  In the 1970’s “he saw the potential in building not just a place for old people to live, but to create a community where there was a love affair for what it stood for …. The sundial is the perfect example of what he stood for. He gave it more hours than there were in a day, it stood one foot taller than its twin in Carefree Arizona and it was all about living life large. Virtually everything he did was bigger and better than what folks expected…” said Dell Webb Museum president. NASS member John Carmichael discussed the unique gnomon that has four shadow casting edges and NASS member Simon Wheaton-Smith talked about how the sundial told time and its features to the many people in attendance.  Letters and email sent from NASS and international Sundial List members were instrumental in the Sun City board decision to save the dial from demolition.  NASS Roger Bailey’s letter to the Sun City administrators was specifically mentioned.

The sundial is located at The Sundial Recreation Center located at 14801N. 103rd Avenue, Sun City, AZ 85351. Photos by John Carmichael.
