Photo Descriptors - Larkin Memorial Sundial

ROW 1
DSC00646.jpg - Note circle of 12 Zodiac signs surrounding base of sundial.

DSC00645.jpg - Bowstring inclined at ~34-degree angle; equatorial band 
inclined at ~56 degrees.

ROW 2
DSC00647.jpg - Two of the more distinctive features of the Larkin Memorial 
Sundial are its modern design and analemma-shaped gnomon.

ROW 3
DSC00635.jpg - View from the west (facing almost due east). The meridian 
band runs north-south; the gnomon, representing the Earth's axis of 
rotation, intersects the semi-circular meridian band at the equivalent of 
the Earth's North and South Poles. Eight year-old boy is 51.5 inches 
(130.81 cm) tall.

DSC00638.jpg - View from the south (facing north), looking along the
meridian band. The equatorial band (time scale) runs east-west
(right-left). Boy is 51.5 inches (130.81 cm) tall, shown lying along the
time scale. The meridian band ('bow') bisects the equatorial band ('time
scale'); the 12 o'clock noon hour line is located on the time scale where
the two bands intersect (since solar noon occurs when the Sun crosses the
observer's meridian). Facing north, morning times are located on the left
side of the equatorial band; afternoon times are on the right.

ROW 4
DSC00636.jpg - Close-up, Garmin Geko 101 GPS receiver showing exact 
location of sundial (+/- ~20 ft.).

DSC00637.jpg - Close-up, Larkin Memorial Sundial commemorative plaque.

ROW 5
DSC00639.jpg - Analemma-shaped gnomon shadow, plus Garmin Geko 101 GPSr. 
Note that the dates shown along the sundial analemma (inscribed on the 
equatorial band) appear backwards compared to a globe analemma. Remember, 
Sun shadows fall in the opposite direction as the Sun.

ROW 7
DSC00634.jpg - The hour lines for the bowstring equatorial sundial are 
laid out on the inner surface of the equatorial band. Every hour is 1/24 
of a day, or exactly 15 degrees wide. The shadow of the gnomon (or style), 
cast among the hour lines on the equatorial band, shows the time.

DSC00648.jpg - View from the north (facing south), looking along the
meridian band. The equatorial band (time scale) runs east-west
(left-right).
