Sky's Up January-February 2018 | Page 54

on the road with Doveed Two magic minutes worth the trip By DAVID H. LEVY Sky’s Up Editor in Chief What happened on August 21, late in the summer of 2017, was breathtaking, incredible, and incomprehensible. An eclipse of the sun is actually very simple — a cosmic coincidence during which the Moon passes in front of the Sun. Because Wendee and I were in the path of totality, we saw a total eclipse, which is a lot more than science, and which is not so simple. We left Tucson on August 19th, traveling by airplane to Los Angeles and thence to Redmond in Oregon. We arrived in Madras a few hours later, and over the course of the next day joined with several of our friends who had agreed to make a similar trip. The eclipse began promptly at 09:07 a.m. on the 21st. As the Moon took its first tentative bite out of the Sun, the eclipse appeared to be as simple as described; as more and more of the sun was covered by the moon the temperature began to drop, slowly at first, and then more precipitously. And with less sunlight, shadows of buildings, trees, and people became sharper. But still the eclipse was a simple event—until totality came. As the shadow of the Moon approached us, the solar crescent became a thin line of light. As the light began to thin even further, it broke into a multitude of points. Bailey’s Beads! First described by Francis Baily at the annular eclipse of May 15, 1836, these tiny beads of sunlight peering through valleys at the edge of the Moon, precede and follow totality. Within a second or two those beads vanished, all but one. At that one moment, the Diamond Ring, the simplicity of the eclipse utterly transformed itself into a complex symphony of magic, beauty, romance, emotion and wonder. The corona, the Sun’s atmosphere, stretched several solar diameters out into space; actually it reaches Earth. Two minutes later the shadow left us and continued its journey across the United States. Thousands upon thousands of other people would get to see much the same thing we did in the next couple of hours. 54 COURTESY OF David H. Levy This image, taken near the middle of totality, reveals the inner corona showing a prominence. Does this seem like an awful lot of travel for just two magic minutes? Was it worth it? Absolutely, you bet! To stand in the shadow of the Moon, witnessing the onset of darkness in the middle of the day is an experience I shall never forget as long as I live. Nor will all the people who traveled to share the experience with us. Ika Hackett, who had traveled with her family from Canada, set up a white sheet in hopes of catching the shadow bands. This effect, which takes place in the seconds just before and after totality, is very difficult to see. Sadly, she told me that she had failed to see them. “I did see a faint rolling effect of light and darkness that lasted for a few seconds.” “Ika!” I answered her. “You saw the shadow bands. that’s what they often look like!” The play of light and shadow is very subtle indeed. At only one other eclipse did Wendee and I see better shadow bands. Instead of a small white sheet to cross over, the play of light and shadow had an almost unlimited expense of Antarctic ice to play with. At the eclipse of November 2003 in Antarctica, we saw 12 minutes of shadow bands. This time we didn’t have to travel to the ends of the Earth to see them. The following day we had to wait several hours for our long delayed flight back home. But it didn’t matter. We had been witness to one of the most spectacular events nature can provide – a total eclipse of the Sun. Sky ’ s Up A partnership written in the stars By WENDEE WALLACH-LEVY Guest Contributor No matter what I chose to do in life I was always the organizer. As a physical education teacher and coach, I organized all the in class tournaments, the intramural activities in my schools as well as the after school activities. My days were long, and my weekends non-existent as they were filled with school sporting events. On the occasional weekend when no school events were planned, I did volunteer work for our local American Red Cross Chapter. There, I organized the annual Learn to Swim programs in the city of Las Cruces, N.M. Before I retired from teaching I was the chair of the local Health and Safety Services Committee. As if I didn’t have enough to do I moonlighted for New Mexico State University at the Weekend College on Sunday afternoons. Without going into great detail about each area I organized I viewed the rare free weekend as a vacation. I used to wonder, after all the organizing I did during my 26 year teaching career, what it would be like to organize a famous person. (This was way before I had met David). Needless to say, when David and I eventually did get together I was ready to keep his life organized but totally unprepared for what I thought would be a fairly simple transition. When it became obvious that I was going to formally retire from teaching and move out to Tucson and co-habitate with David, this is how I broke down our tasks. I began by confiding to David that I knew comparatively little about astronomy, but did know enough to see through a situation/ problem and intuitively know what needed to be done. Then I objectively looked at our strengths and naively said these words: You are a wonderful astronomer, lecturer and writer, I will take care of everything else. (What was I thinking?) At first David disagreed. He knew how hard I worked in Las Cruces and he wanted to take care of me and let me just relax and enjoy the ride. That didn’t last long. By the end of our first week, I took over the bill paying and the shopping, and 21 years later I am back to doing what I originally suggested. For those of you familiar with the Rocky movies, especially Rocky 1, this needs no explanation. One of the strengths of our marriage is that our strengths are so different, there is no comp
