The heat of summer hasn’t yet passed, even though we’re past “seasonal summer” and are almost at “meteorological fall.” Yes, the autumnal Equinox is almost upon us, arriving on September 23, at 2:50 am CDT. Even though the term means “equal night,” the day is longer than 12 hours on an equinox because Earth’s atmosphere refracts sunlight. Why does day insist on exceeding its boundaries, you ask, and not be content with with “equality?”

Refraction, or bending of the light, causes the Sun’s upper edge to be visible from Earth several minutes before the edge actually reaches the horizon. The same thing happens at sunset, when you can see the sun for several minutes after it has actually dipped under the horizon. This causes every day on Earth – including the days of the equinoxes—to be at least 6 minutes longer than it would have been without this refraction. The extent of refraction also depends on atmospheric pressure and temperature. It’s the nature of days to want to be longer, or if they’re like my little girl, to want one more story or just one more drink of water before the lights go out for nighty night.
This is the season of sunflowers, and they bring light inside when we want to keep the shades down or the curtains drawn to keep the hot sun from cooking our dwellings and driving up our air conditioning bills. I’d bought some blooms to brighten my home and enjoyed them while I repainted my condo. They died during this weeklong endeavor. Afterwards I took a break from wall painting to do some canvas painting. I decided to paint the dying sunflowers.
Van Gogh painted numerous sunflowers, often in vases, but he also painted canvases of the flowers with no background or container. One had double heads, but the other larger one had four life sized dried heads and is approximately 24” x 39.” He painted it between August and October, 1887. Van Gogh often painted flowers to practice color combinations. Some think he saw the sunflower as a symbol for the bright sun of the south of France, the light of which permeates his paintings. His friend and art colleague, Paul Gauguin traded his work for one of Vincent’s dried sunflower paintings.
