New Amateur Comets
The first of the new comets was bagged on March 11th. Douglas Snyder swept up the faint object in Aquila while scanning the predawn skies with a 20-inch f/5 Dobsonian telescope at his backyard observatory in Palominas, Arizona. Seven hours later, as dawn approached Japan, Shigeki Murakami in Matsunoyama, Niigata Prefecture, picked up the interloper with his 18-inch f/4.5 reflector. Designated Comet Snyder-Murakami, C/2002 E2, the object is currently visible in medium-size telescopes as a 10th-magnitude glow moving north-northeast in the morning sky, from Aquila to Sagitta and then to Vulpecula.
"This is such a rare and rewarding event," says Snyder, "and I'm still so overwhelmed at my luck in finding it."
The last time a comet was discovered visually in the United States was on April 22, 1998, when Patrick L. Stonehouse of Wolverine, Michigan, discovered C/1998 H1 with a 17½-inch reflector.
Just one week after the Snyder-Murakami find, in the early morning twilight of March 18th, Japanese observer Syogo Utsunomiya discovered another comet with a pair of 25x150 binoculars. Experts have yet to calculate the orbit of the new object (dubbed C/2002 F1), but for the past couple of days, the fuzzy ball has shone at 11th magnitude in Pegasus.
Below is a table listing the magnitude and location of Comet Snyder-Murakami. A similar listing for C/2002 F1 will become available when its orbit is determined.
