Koyama shivered under his hat and overcoat as he scanned the sky night after night. A bout of influenza kept him off the roof till the twenty-second, and he was annoyed to discover that Seki and Ikeya had together discovered a new comet while he was laid up. Increased dedication and vigilance, he vowed again.
The morning of the twenty-third, Mr. Koyama finally found his comet. There, near the not-yet-risen sun, he saw a fuzzy ball of light. He sneezed, gripped the Fujinans tightly, and gazed up again to confirm the sighting. Nothing else should be in that part of the sky.
His heart pounding, Mr. Koyama descended to his study and picked up the telephone. He called the telegraph office and sent a wire to the International Astronomical Union. (Telegrams are de rigueur with the IAU; a telephone call would be considered vulgar.) Offering vague prayers to a host of gods in which he did not profess actual belief, Mr. Koyama returned to the roof with the strange feeling that his comet would have disappeared while he wasn't looking. He breathed a sigh of relief.
The comet was still there.
The confirmation from the IAU came two days later, and confirmed as well what Mr. Koyama already knew from his own observations: Koyama 1983D was a real whizzer. It was flying from the sun like a bat out of hell.
Further reports indicated all sorts of anomalies. A routine spectrographic analysis showed that Koyama 1983D was a decidedly odd duck indeed: instead of the normal hydroxyls and carbon, Mr. Koyama's comet registered large amounts of oxygen, nitrogen, hydrogen, carbon, silicon, and various mineral salts. In short, all that was necessary for organic life.
A storm of controversy immediately arose over Koyama's comet. How anomalous was it, and was organic life possible in the cold and dusty ranges of the Oort Cloud? Mr. Koyama was interviewed by teams from the BBC, NBC, and Soviet television. He was profiled in Time magazine. He offered modest statements about his amateur status and his astonishment as to all the fuss; but he was inwardly more pleased than he had been over anything, even the birth of his eldest son. His wife observed him walking about the house with the strut of a twenty-year-old and the broad grin of a clown.
Every night and morning, Mr. Koyama was on the roof. It was going to be hard to top this, but he was going to try.
Part Two: October 1985
Astronomy was getting more attention these days, what with the reappearance of P/Halley 19821, but Mr. Koyama maintained his equilibrium in the face of the turmoil. He was an old hand now. He had discovered four additional comets since Koyama 1983D, and was assured of a prominent place in cometary history. Each of his cornets had been the so-called 'Koyama-type' comets with their weird spectrography and their bat-out-of-hell speed. Koyama-type comets were being discovered by all manner of amateurs, always hugging the sun.
The controversy had not died down; had in fact intensified. Was it possible that the solar system was passing through a storm of comets containing organic elements, or was this a fairly ordinary occurrence that somehow hadn't been noticed till now? Fred Hoyle smiled and issued an I-told-youso statement reiterating his theory of cosmic seedlings containing organic life; and even his bitterest opponents conceded that the annoying old Yorkshireman might have won this round.
Mr. Koyama received many invitations to speak; he declined them all. Time speaking meant time away from his rooftop observatory. Currently the record number of comet discoveries was nine, held by an Australian minister. Mr. Koyama was going to win the honor for Japan or die trying.
Part Three: Late June 1986
There: another comet, barely visible, chasing the sun about the sky. That made six altogether. Mr. Koyama descended to his study and called the telegraph office. His heartbeat increased. He needed confirmation on this one desperatelynot confirmation of the sighting, but of the spectrography.
Mr. Koyama was climbing the charts of comet-sighters, and this was in a period of a nervous, -increased watching of the sky: people were looking up a lot these days, hoping to find the dark nonreflective Swarm parent that was presumably lurking nearby. But the prospect of number six wasn't what excited Mr. Koyama-he was getting fairly blase about finding new comets these days. What he needed was confirmation of his new theory.
Mr. Koyama accepted the congratulations of the telegrapher and put down the telephone. He gazed with a frown at the chart he had
