The first of the new meteors landed on the earth in November, 1940. It was discovered by a farmer in his field near Brookline, Massachusetts, shortly after daybreak on the morning of the 11th. Astronomically, the event was recorded by the observatory at Harvard as the sudden appearance of what apparently was a new star, increasing in the short space of a few hours from invisibility to a power beyond that of the first magnitude, and then as rapidly fading again to invisibility. This star was recorded by two of the other great North American observatories, and by one in the Argentine Republic. That it was comparatively small in mass and exceedingly close to the earth, even when first discovered, was obvious. All observers agreed that it was a heavenly body of an entirely new order.
The observatory at Harvard supplemented its account by recording the falling, just before dawn of the 11th, of an extraordinarily brilliant meteor that flamed with a curious red and green light as it entered the earth’s atmosphere. This meteor did not burn itself out, but fell, still retaining its luminosity, from a point near the zenith, to the horizon.
What the farmer saw was a huge fire burning near the center of his field. It was circular in form and about thirty feet in diameter. He was astonished to see it there, but what surprised him more was its peculiar aspect.
It was still the twilight of dawn when he reached the field. He beheld the fire first from a point several hundred yards away. As he explained it, the light—for it was more aptly described as a light than a fire—extended in parallel rays from the ground directly upward into the sky. He could see no line of demarkation where it ended at the top. It seemed to extend into the sky an infinite distance. It was, in fact, as though an enormous search‑light were buried in his field, casting its beam of light directly upward.
But more than all this, the farmer was struck by the extraordinary color of the light. At the base it was a deep, solid green. This green color extended upward for perhaps fifty feet, then it shaded into red. The farmer noticed, too, that the fire did not leap and dance with flames, but seemed rather to glow—a steady light like the burning of colored powder. In the morning half‑light it threw a weird, unearthly reddish‑green glow over the field…
