At 6:45 PM, I had an impromptu eclipse date with the sun and moon. I'd forgotten all about it until a friend posted something about the
eclipse on Facebook. I dropped everything and made a mad dash for the door. But we were not in the path of totality. My Mylar
eclipse glasses from the
Hawaiian total
eclipse on
July 11, 1991, were up in Forestville, I was completely unprepared to view this partial eclipse, what would work? I could think of nothing, other than some old Mylar hard drive bags. Bingo! I dragged a box of computer parts from the morgue, left a constellation of old hard drives and memory cards scattered all over the bed, trying to find a good Mylar bag. I was running out of time.
I ran out in the street and viewed the sun through the old Mylar hard drive bags, looking like some street loonie. Passersby stared, but I didn't care. However, the fog bank kept thrusting its tongue out. I was determined; something about seeing eclipses changes how you think. So I drove up the hill to the next clear spot in the road unhampered by high rises.
The Mylar bags worked, but were less successful, they were too thin, I couldn't see through multiple layers and the one really dense Mylar bag was too warped or full of minute holes for true viewing pleasure. But I had all kinds of eclipse viewing tricks up my sleeve leftover from childhood. I ripped the cover off a paperback book and punched a hole in it with a ballpoint pen. The pinhole camera idea wasn't working out, nor were the tree leaves cooperating. The sun was too low on the horizon to cast myriad eclipses on the ground through tree leaves.
It's a little known fact that trees cast myriad images of the sun on the ground. All those funny little circles of light are really projections of suns. Trees make natural pinhole cameras. During an eclipse, the ground beneath the trees is covered with hundreds of eclipse shadows. You just have to know where to look. A piece of white cardboard helps put it into focus. Oak trees work best. How very druidic. Must be something about the negative spaces created by oval leaf shape of oaks as pine needles are too thin.
I discovered the pinhole camera effect by accident Feb. 26, 1979, when I was pinning something up on the kitchen wall, I was living in Cotati with Sweet Old Bob, but that's another eclipsed story.
I was admiring some shadows cast on the wall by a rockrose succulent I had hanging out the kitchen window, they looked very Japanese sumi-e, but there were funny little moving crescents on the wall. WTF? Ants? Small spiders? I went to get my camera to document the strange moving shadows, and then I realized the light outside was strange...it was far too dark for noon, no clouds in the clear blue sky. Hmmm.
Then it dawned on me: it was a total
eclipse of the sun, I had no idea...my rockrose informed me. Too afraid to look directly at the sun, as we were not quite in the path of totality (Washington to Greenland), I don't remember seeing Bailey's beads, nor the diamond ring, just a slivers of light, like the half moons on my fingernails.
Wherever the rockrose needles intersected each other, they made a natural pinhole camera with myriad "lenses." I madly took photos of eclipse shadows. I made pinhole cameras, used my hands to cast eclipse shadows, I was clean mad with the joy of discovery. Even the eucalyptus tree was celebrating the eclipse....there were eclipse crescents everywhere on the ground.
Surely this phenomenon had been discovered before, but by whom? Lost in the mists of time. I was a modern day
Sor Juana de la Crúz experimenting with light and shadow. I was totally in the zone—jazzed by the adrenaline rush of discovery and excitement....but I was home alone, no one to share it with.

Chasing the setting sun, I parked the car at the top of MacArthur and Adams Point, darkened the car with my car shades and got innovative, asking "what if..." I set some reading glasses in a beam of light on the dashboard and got little twin eclipses projected onto the car door, but then, too soon, they disappeared.
I tried using double sunglasses to view the sun as it hid behind a cloud bank, and marveled over the rainbow colors I could see through the polarized lenses, and then it came to me in a flash: I thought, what if I have the wrong day, what if there's no eclipse and I'm looking straight into the sun's corona like a mad dog? Will I go blind due to some cosmic joke?
I drove home disgruntled, thinking my experiment had failed, only to find I'd caught the ratass end, not the beginning of the eclipse. Then I found out that it began at 6:15, not 7:15. Where did I get that info from? Probably from somebody living on Mountain Time.
But I was pretty chuffed over resorting to reading glasses trick—you know how you can sometimes see rainbow hued suns on the ripples of a lake or on the beveled edge of a rearview mirror? That's what gave me the idea. That, and the crystal heart dangling from the rear view mirror. Association by degree. To use the reading glasses as a projector telescope. Focus was easy, about 2 feel from the door, once I lined the glasses up to the sun.
I experimented with tilting the lenses, etc., and I was able to make surreal 3-D parallax suns, reminding me that the eclipse image I was seeing was really projecting upside down. Just like when you take a magnifying glass and hold it away from you and everything turns upside down. Add another magnifying glass in front of it, and you can set the world right again. Sometimes I do that trick with kids to blow their minds. That, and using old CDs to throw rainbows across a crowded room.

It's a little known fact that we actually see the world upside down. Which explains a lot. Our brain processes what we see and sets it right side up. Light bounces off the retina, and crosses paths entering the optic nerve for the brain to decode it. Pretty cool stuff.
So, I was feeling a bit like the unschooled Dutch scientist
Antony van Leeuwenkoek (1632-1723), who felt that the best teacher was an open mind uncluttered by scientific dogma. Well, I had that. He valued curiosity, and said to observe, observe, observe, and then experiment—and so I did.
Son of a brewer and a basketmaker, Van Leeuwenhoek was a highly unlikely candidate for scientist. Friend of Vermeer, he was attracted to light, he also as a lens grinder and maker of spectacles (lately so relevant in my life), which led to his invention of the microscope: a lens and a pinhole of light. A focal plane. Much like the inner workings of the Nikon camera lens
aperture I held in my hand. That, and Gallileo's telescope.
Unfortunately the photos I took were post eclipse phenomena, I was too distracted by technical difficulties, only able to eke out 2 photos due to dead batteries, but it does illustrate my point, albeit a
Khruschev's shoe photo—after the fact.
I marveled at the rainbow fringe cast around the edges of the sun images and was reminded of another lensmaker, an English contemporary of van Leeuwenhoek's who noticed rainbows cast on the edges of a ground lens he was working on in a darkened room.
This observation led to
Sir Isaac Newton's (1643-1727) famous 1704 magnum opus,
Opticks: a Treatise on the Reflexions and the Refractions and Inflexions and Colours of Light, and the discovery of the color spectrum revolutionized the work of poets and artists. Suddenly paintings were full of prismatic color and poets harnessed the metaphor of rainbow.

Reflection, absorption, transmission, wavelength. I tried an experiment with two pairs of reading glasses and discovered that two lenses cancelled each other out and dimmed the image of the sun. But then I had four eclipses projected on the wall!
Sitting in my darkened car, I felt like I was inside the Camera Obscura at the Cliff House in San Francisco watching twinned projected suns on the doors of my car. It worked really well, you could even see the layers of cloud bank in front of the sun.
Forgive me Antony van Leeuwenhoek for standing on your gravestone. I meant no disrespect. Coming in from the bright sun into the dimly lit church at Delft, I was purblind. I looked for you in vain, until my friend Vins said, "you're standing right on top of him!" With your lenses you gave us entrance to a cognate miniature worlds of animalcules—inner constellations of foramifera and spirogyra held in a single drop of lake water. And camera lenses. Our world has never been the same, wee beasties, and all.
I'm still seeing sun spots before my eyes.
PS I found the time error, from a forwarded email from Antonia Lamb, who gave lots of astrological implications as a gateway to great power, but listed the eclipse at 7:30 PM. Always double check the facts, ma'am.
