Skyward Dec 2023 with Dr. David Levy

Skyward for December 2023 By David H. Levy On the fourteenth of October 2023, I witnessed my 99th eclipse. This tally includes everything from barely noticeable penumbral eclipses of the Moon, where one can occasionally distinguish a slight shading of one side ofc the Moon as it wanders past the Earth’s outer shadow, to the dramatic and life-affirming total eclipses of the Sun. The October eclipse was actually an annular eclipse or “ring” eclipse. The annular phase occurs during which the entire Moon covers the Sun, but because the Moon is near its apogee, or farthest point from the Earth in its orbit, then the Moon is surrounded by a ring of sunlight. I was all set to join the group heading to southern Texas to see the annular eclipse, but last month I was invited to be the keynote speaker at the Homecoming festival at the State University of New York at Plattsburgh. This invitation meant so much to me that I was not about to pass it up. So, I took a big chance, and it paid off. The night of my lecture was clear and starry. I began the lecture with my own definition of what a university can be. The world is as it is; we can try but, in the end, it is difficult if not impossible to change it. A university, however, at its best represents the world as it can be. For me, this represents the ideal of what a university can accomplish. The case of SUNY Plattsburgh is a specific example of that possibility. The not-too-large student population, understandable relationships among students and faculty, careful and interesting course offerings, and even the Plattsburgh Cardinals sporting program, all help to promote this goal. But this University offers one thing more. About 40 miles to the south, within the ancient Adirondack mountains, lies their rural campsite called Twin Valleys. As a youngster I attended the Adirondack Science Camp there in what were three of the happiest summers of my life. And for the past 20 years there has been the Adirondack Astronomy Retreat at this magnificent place. On the eve of the eclipse my friend Ed Guenther and I led a small group of people to observe at our Adirondack Astronomy Retreat site, during which time I did a little comet hunting. The following morning the sky was cloudy but there were plenty of breaks in the clouds so we got a magnificent view of the partial eclipse. We were excited; the crowd was excited, and we thoroughly enjoyed the partial eclipse that lasted about two hours. During this excitement, the solar system continued its inexorable motions, as the Earth, the Moon, and the planets slowly wended their way through space and time.
