Frans Maes Received a Royal Decoration
Monday, 24 March 2025 21:33
Several years ago Frans decided to write the course on sundials that included self assessment questions to force students not only to read the text, but to internalize the concepts. And a final submittal question "not necessarily a difficult question, but: no answer, no new lesson." Thus Frans Maes began writing lessons and sending them out to students.
NASS has now used his material to create...
500 Foot Tall Gnomon Project

While using Google Maps, some artists living in the UK became unusual dialists when it occurred to them that the shadow cast by a skyscraper could be used as the gnomon of a really tall sundial.
The forty-seven story Beetham Tower in Manchester is 554 feet tall and dominates the city's skyline. So it occurred to Annie Harrison, Jude Macpherson and Jacqueline Wylie to use the shadow cast by this structure to chart the progress of the sun as part of an art project.

Its not often a sundial is also a monumental piece of sculpture weighing tons, but that is what developer Fred Steiniger installed this May at the Innovation Corporate Center in Oro Valley, Arizona. Long-time NASS member and professional dialist John Carmichael was intimately involved with the 3-year long project, which is still ongoing. Carmichael still has to install a noon-line sundial. Project completion is sometime this year before the planned dedication slated for noon at Autumnal Equinox.

Located in Port Angeles, Washington, Peninsula College recently dedicated a sundial measuring eight feet in height. The dial is notable for its unusual design: the basic construction is one of a polar dial, but also includes the sun's analemma so dial viewers can correct for the equation of time.
The dial was designed by the late Ben Davis and donated to the school in his honor by Honey Davis, his mother. Installed on campus near the Science and Technology Building, Dr. Tom Keegan perhaps expressed sentiments the best when he said, “Honey Davis’ very generous gift to Peninsula College is deeply appreciated. It’s fitting that it be placed by our Science and Technology Building so that Ben’s amazing engineering skills serve as an inspiration to our students and encourage them to stop and look and study his sundial."

A nearly twenty year project to build a sundial near the Arctic Circle in Fairbanks, Alaska was finished this year by Martin Gutoski, a professional surveyor. Gutoski conceived the idea in 1992 when he reviewed a survey for the local library in Fairbanks’ North Star Borough. Originally out of concern for safe-guarding survey corners, he got in contact with a local club whose members saw to the landscaping of the library and other public buildings. One thing lead to another and so began the odyssey that ended just recently.
One interesting aspect that will appeal to anyone who has ever built or contemplated building a sundial is that the dial location is only about one and one-half degrees south of the Arctic Circle. This is an aspect which Gutoski fully explored with models, first a small one and later a full-scale wooden one, before committing the design to its final form, which uses an airplane propeller for the gnomon.

Sundial Wrist Watch
- Details
- Hits: 16671
A novel wrist watch is being proposed which uses LED's instead of the sun to cast shadows. Proposed by an individual named Anders who lives in Sweden, the watch, which is still just a concept, is read much like a conventional analog watch. But instead of an hour hand and a minute hand, it uses LEDs which rotate around the outer ring of the dial and shine on a small gnomon at the center of the watch. One LED casts a shadow for telling hours and another for telling minutes. It is too soon to tell whether this concept watch will prove popular enough to manufacture.
Parasol Sundial

Primarily an industrial designer, Kota Nezu has designed a parasol for people who use their umbrellas for shade as well as staying dry.
With just a little bit of effort, Nezu's dial can be used to tell the approximate time of day and season of the year. The parasol comes equipped with a small compass to aid in lining things up. And even though a true sundial aficionado might point out that a proper dial has to be designed for a specific latitude, this handly umbrella is sure to be a conversation starter come rain or shine.

Carefree Dial gets a Sunburst

- Hits: 9368
The first sundial in the NASS Registry is the dial from Carefree, Arizona. This 35 foot tall dial was designed by architect Joe Wong and solar engineer John Yellott and when built in 1959 was considered the second largest sundial in the world. You can see in the accompanying photo that hanging midway along the sundial's gnomon is a garish colored ball, a "Sunburst". [It is partially hidden by a background palm tree.] This structure was part of the original design. From the on-line Carefree City SunTimes, editor-in-chief Kathryn Miller brings us the story of its origin, demise, and now its restoration. The seven-foot wide wrought iron Sunburst has not been on the gnomon for the last 20 years. From Miller's article, "As the story was told by Carefree Vice Mayor John Crane in his March CITYSunTimes column, “The Joe Wong designed Sunburst enjoyed a short life. In 2004, when the Sunburst was determined to be beyond repair it was donated to the Cave Creek Museum where it resided outside for many years."
Eventually the museum returned the rusting icon to the City of Carefree, ending up in the Town garage. Miller's article now reports it's restoration that was completed in March 2021: "...[Back in] 2019, a Carefree resident, who prefers to remain anonymous, took it upon himself to return this misplaced, but not forgotten, historic and iconic art piece to its rightful place. Now, a reincarnated Sunburst, dimensionally identical to the original, but with improved design and modern materials, holds a place of honor in the Town center, once again celebrating the desert sunshine and casting its glow beneath the Sundial."
Perhaps an indicator of the times with the urge to turn night into day, this Sunburst that hangs on the gnomon is now electrified and illuminate with LED lights, blending in with the LED lighting of surrounding cactus in ithe plaza.
