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...

Shelbyville Sundial
Wednesday, 13 November 2024 19:36
It isn't often that a sundial face is created before the gnomon is attached. In Shelbyville IN a large, circular art piece in the form of a sundial, was created at the Blue River Trailhead early in 2024. If they had chosen an analemmatic sundial, a walker of the trail could have simply stood on the appropriate date and used his or her own shadow to tell the local solar time. ...

The armillary was a gift to the university on its 50th anniversary in 1962 by the Miami chapter of Tri Delta. [See the NASS Registry for details]

In November 2024, a team consisting of members from SPL, TTDG and CMD of VSSC successfully designed and installed an accurate and fully functional sundial at the Rocket Garden of VSSC Space Museum, Thumba (8.53°N, 76.86°E). Following a space theme, the vertical gnomon is a 3-stage rocket that casts its daily and seasonal shadow on a dial face 1 1/2 meters by 1 meter. The the sundial face is the top of a wedge with an angle of 8.53°. Instead of hour and minute lines, every 15 minutes shows a complete analemma with the path from December to June in red and from June back to December in blue. The dial is corrected for longitude and shows Indian Standard Time from 9:00 to 15:30.

It isn't often that a sundial face is created before the gnomon is attached. In Shelbyville IN a large, circular art piece in the form of a sundial, was created at the Blue River Trailhead early in 2024. If they had chosen an analemmatic sundial, a walker of the trail could have simply stood on the appropriate date and used his or her own shadow to tell the local solar time. But Shelbyville residents have a more ambitious plan. The artistically paintedd design is a typical horizontal sundial, requiring a real slanted gnomon. In a news article by Jeff Brown in The Shelby County Post for Nov 12, 2024, "The Blue River Community Foundation received approval Tuesday morning from the Board of Works and Public Safety to purchase and install a gnomon that will turn the art piece at the Blue River Trailhead just north of downtown Shelbyville into a functioning sundial." According to the article, the completion of the sundial will be paid for by grants and private donations.
Photo from The Shelby County Post with a "birds eye view" insert of the sundial layout. The gnomon will cross half or more of the path.

For two years News Atlas (https://newatlas.com/architecture/) has reported on the progress of the construction of the Sun Tower in Yantai, China. The 164-foot (50m) curved conical tower was designed by OPEN Architecture symbolized the watch towers of the Ming dynasty (1368 to 1644 CE) that looked out over the coastline to warn of impending attack from the sea.
Adam Williams in the Nov. 4, 2024 issue of News Atlas provides another "infomercial" on the Sun Tower completed and opened in November on schedule:.
"Informed by meticulous studies of the Sun, the northern edge of the building is parallel to the noon sunlight of the equinoxes, while the entrance tunnel aligns with the sunset during the Winter Solstice," explains OPEN Architecture. "Sitting at the center of the Sun Tower is a semi-outdoor theater, which has been orientated with its central axis pointing towards the sunrise over Zhifu Island on Summer Solstice."
"Facing the ocean, the concave inner shell absorbs the sounds of the ocean, amplifying back through the structure, and down to the amphitheater at the base. Radiating from the center of the Plaza is a series of elliptical rings, resembling planetary orbits. A water channel is carved into the stone pavement. The intersections between the rings and the water channel mark the building shadow at specific hours during the equinoxes, and one outer ring features a series of fountains that celebrate the 24 solar terms of the traditional Chinese calendar."
This is an impressive structure.
