Touching the Stone

George Kelley, Jr.



In the year 1970, I began making systematic observations of variable stars. Not all stars are constant in their brightness. Some are multiple star sytems in which one star eclipses another causing variations in their combined light; some single stars pulsate over periods of days, weeks, or months; some multiple stars exchange material, often with explosive results; some stars, if massive enough and near the end of their lives, literally collapse and then tear themselves apart in a tremendous outpouring of energy that for a short time exceeds the total energy expended by all the stars in an entire galaxy. Variable star observers salivate over such things.

Watching the variation in the brightness of stars is not simply a game. Variable star observers faithfully record their observations and report them monthly to a central repository. There the information waits for professonal astronomers who use it in their studies to determine the nature, evolution, and ultimate fate of stars.

Soon after becoming an observer and measurer of variable stars, I became friends with a wonderful person in Ohio. Carolyn Hurless was outgoing, enthusiastic, possessed of an inquiring and brilliant mind. Each year, in August, Carolyn invited her variable star observing friends to visit her and her husband Don for a weekend of good food, endless conversations and music. Among my fondest memories of variable star observing are memories of these "August Orgies" as Carolyn named them.

At left, George Kelley, Jr., lines up the 12.5-inch reflector in his backyard observatory to observe the cataclysmic variable SS Cygni. Blue dots on the graph represent several years of observations by all AAVSO members; purple circles are George's observations; pages of notes record estimates of the star's brightness -- one estimate per line.
Carolyn's friends were deeply moved and saddened by news of her untimely death on February 13, 1987. One of our number, Paul Sventek, native Chicagoan, now a resident of Houston, TX, met Lowell Observatory staff astronomer Brian Skiff when Brian addressed a gathering of amateur astronomers in Houston. Over the years, Brian has discovered several asteroids. These small "planets" generally inhabit the space between the orbits of Mars and Jupiter.

Now, the discoverers of asteroids are allowed to name their discoveries once their orbits are well established. Paul prepared a formal nomination and asked Brian to name one of his discoveries for our friend Carolyn in memory of her and in honor of her contributions to astronomy. Brian agreed to do so. When the orbit of the asteroid formerly known by the preliminary designation "1981 VO" was settled, the International Astronomical Union gave the asteroid the number 3434 (in order of discovery) and the name "Hurless." (Carolyn's friends are pleased with a coincidence involving the two pairs of digits, 34 and 34: 1934 was the year of Carolyn's birth.)

Not long after Carolyn's asteroid was named, David Cortner calculated when over the next few decades the asteroid would come nearest Earth. Our best viewing opportunity would come in early October 1998. Even then, the small planetoid would be a faint object, testing the limits of our vision and the largest telescopes we owned. What better way to continue our tribute to Carolyn than to attempt to see the asteroid named for her? That thought simmered in the backs of our minds over the years. The summer of 1998 rolled around. David said to me, "Hey George, let's get the gang together and go for 3434 Hurless."

Invitations went out to Carolyn's husband Don in Ohio, to Paul in Texas, and to Gus Johnson in Maryland. The weekend of October 17th was chosen to assure us of a sky unpolluted by the light of the Moon. It did not assure us of clear weather, but October is statistically the clearest month of the year in southwest Virginia.

The first night of our search was clear. The asteroid, however, was located in an area of the southern sky devoid of bright stars from which to begin our "star-hop" to its mapped position. After three or four attempts, I managed to use my 12.5" reflector to locate the field of stars in which Carolyn's namesake lurked. Try as we might to see it, it eluded us. A defeated group of observers went to bed after 1 A.M., Saturday, still yearning for a glimpse of the elusive hunk of space rock.

Saturday evening was clear as well. While Don, Gus and I shared telescopic views of the heavens with local visitors, Paul and David undertook to locate the position of the asteroid in David's 16" reflector. Finally, at 11 P.M., David and Paul reported an extremely faint object near the calculated position of 3434 Hurless. I also took a peek, and sure enough, there glimmering, oh so faintly, was a "star" where star charts showed none. But we still would not claim victory until gathering more evidence.

Our friend Murray Cragin down in Florida sent us by e-mail a chart that showed stars much fainter than the asteroid. With that chart in hand, we were certain we had not seen a star: we had seen 3434 Hurless. On Sunday afternoon, we finally declared our search a success. We had come full-circle: we had figuratively touched the stone named for our friend.
