Sky & Telescope - December 2018 - 69
than in the same time in December."
Jay used an idea from an old Chinese sundial that lets sunlight through
a small hole in a large disk. That way
there's a big shadow with a bright spot in
the middle, which makes it easy to read
from a distance. Of course, Jay's shadow
disk is a representation of the Sun.
Jay started the project in early June
of 2017. After mounting the gnomon
near the peak of his roof, he started
marking points on the solstice, June
21st. At 15-minute intervals he marked
the outline of the spot, and those spots
became the long row of ellipses at the
bottom edge of the field. Each month, on
or about the 21st, he did the same thing.
The equinoxes on September 22 and
March 20 were the dates for the single
straight line across the center. Additionally, at exactly clock noon he made
another point along the analemma. Connecting those dots created the figure 8.
For the final artistic presentation,
Jay chose to make the sundial represent its home: the state of New Mexico.
The equinox line became Route 66, the
watermelon slice
is a tribute to the
beautiful Sandia
(Watermelon)
mountains, and
the whole works
is framed in
turquoise, New
Mexico's state
p The pointer spot ilgem. The balloon

commemorates
special moments.
the Albuquerque
International Balloon Festival.
Jay has also marked several personal
moments on his sundial. And the motto
at the bottom comes from the very last
line of an essay a family friend wrote
before he died.
Jay has created a beautiful and highly
functional work of art. You could, too!

S&T's Eclipse Flight:
Chile July 2, 2019
From the vantage point of an A320 aircraft flying 37,000 feet
above the Pacific Ocean, you'll be high above any clouds that
might lurk below, seeing up to 3¼ minutes of totality in a dark
sky that makes the Sun's corona look incredibly dramatic.
Our flight will depart from and return to Santiago, Chile.
