The Signora Comes Early

The dish stood on the shoulder of the mountain above the Fucino, nine metres across, and it had not moved in azimuth since 1998. Nobody had told it to. The telephone company had closed the station in March of that year, taken away the racks and the diesel and the good chairs, and left the dish because it would have cost more to cut down than it was worth as scrap. Ettore Di Giacomo had been its technician for thirty-one years. When they closed the gate he asked for the key, and they gave it to him, because nobody else wanted it.

He had pointed it due south and raised it to fifty-five degrees, and there it had stayed. Every night the sky went through it, from east to west, a strip a little more than a degree and a half wide. Ettore listened to the strip.

Ilaria Pace came up on Saturdays. She was sixteen, in her third year at the liceo scientifico in Avezzano, and the school required her to do a certain number of hours of work experience before she finished. Most of her class did theirs at the bank or the pharmacy. Her grandmother was Ettore's sister. That was the whole of the arrangement.

On the last Saturday of September he was waiting for her at the gate, which he never did.

"I have something," he said. "Come and look, and say nothing for one minute."

The hut was cold. It always was, the stove took an hour to make any difference, and Ettore lit it only when she came. The receiver was a small grey box that cost him ninety euros, plugged into a laptop older than she was. It swept the band from 1,370 to 1,430 megahertz every few seconds and drew the result as a picture, the waterfall, time running down the screen and frequency across. In the middle, a little to the right, there was always a soft brightening, wider at some hours than at others: hydrogen, the cold gas of the galaxy, which is everywhere. Ettore had been watching it for twenty-eight years. He said it was like watching the sea from a window. The sea is always there and it is never the same.

He scrolled the waterfall back to the previous night. Far to the left of the hydrogen, at about 1,381, there was a thin bright line. It was not there, and then it was there, faint, then strong, then faint again, and then it was gone. Between top and bottom, perhaps five minutes.

"Last night," he said. "Twenty-one, two minutes and thirty seconds. That is the middle of the hump." He turned the notebook round so she could read it. He wrote everything in ink, in the square hand they had taught him at the technical institute in 1966.

21/9 — 21:18:52 22/9 — 21:14:47 23/9 — 21:10:41 24/9 — 21:06:36 25/9 — 21:02:30

"Before the twenty-first, nothing. I looked back through the recordings. Nothing. Then she comes. And every night she comes four minutes earlier." He put his finger on the column. "You know what comes four minutes earlier every night."

She did know. She had done it in the spring, in the unit on astronomy, with a diagram of the Earth going round the Sun and a little arrow on the Earth. The Earth turns once with respect to the Sun in twenty-four hours. But it is also going round the Sun, a little under one degree a day, so to bring the same star back to the same place it has to turn a little less. Three hundred and sixty-five and a quarter days in the year, three hundred and sixty-six and a quarter turns with respect to the stars. The star comes back early by a day divided by three hundred and sixty-six, which is about two hundred and thirty-six seconds. Three minutes and fifty-six.

"The stars," Ettore said. "She is fixed to the stars. She is not one of ours."

Ilaria looked at the column for longer than a minute. Then she took a pencil from the jar and subtracted, in the margin of his notebook, which he allowed nobody to do.

"Four minutes and five," she said. "Four minutes and six. Four minutes and five. Four minutes and six."

"Four minutes."

"The stars are three fifty-six. You are ten seconds fast. Every day."

He was quiet. The stove ticked.

"Ten seconds is nothing," he said. "How well do I know the middle of the hump? The line comes up slowly, it goes down slowly, I look at the screen and I say: there, that is the top. I am good, but I am not ten seconds good. Say I am wrong by ten seconds either way. Then your ten seconds is inside my error."

This was true, and she said so. She had a teacher who said that the most important thing in any measurement was to know what kind of wrong you were. Wrong by a little, in the place where everyone is wrong, or wrong in a way that means you are in a different world. Ten seconds with an error of ten seconds is the first kind.

"But it is ten seconds every day," she said. "Your error does not grow. Mine does. If she is a star, then in three weeks she still comes three fifty-six earlier every night, and your mistake in finding the top is still ten seconds. If she is not a star, then in three weeks she is two hundred seconds ahead of where the star would be. Two hundred is not inside your error."

"And then?"

"Then she is not a star."

"What else comes back every day, nearly with the stars, and is not a star?"

"I don't know," she said. "That is the point of waiting."

He looked at her the way he looked at the dish when a bearing made a new noise.

"Write it down, then," he said. "What you think will happen. Before it happens. Otherwise afterwards you will say you knew."

So she wrote, on a clean page at the back of the notebook, under the date: If star: 17/10 at 19:36:00 ± 10 s. If not star: earlier. She worked out the first number at the table with the pencil, twenty-two days of three fifty-six from the time of the night before, and checked it twice, and he watched her check it and said nothing, which was how she knew it was right.

Then they argued about the clock.

"The laptop's clock," she said. "How good is it?"

"Very good."

"How do you know?"

He opened a drawer. Inside, on a coil of cable, was a black plastic puck the size of a biscuit. "This goes on the windowsill and tells the computer the time. It listens to the navigation satellites. It is good to a thousandth of a second. Better than my heart."

"So the clock is not the problem."

"The clock," said Ettore, "was never the problem."

She could not come the next Saturday because of a chemistry test, and the Saturday after that her father needed her at the warehouse, because the carrots were coming out of the Fucino by the lorry-load and the women on the sorting line were two short. She phoned him instead, on Sunday nights, and he read her the numbers.

The signora did not come every night. On the third of October there was nothing at 1,381 at all, the whole night, and Ettore sat up until two in the morning to make sure. On the fourth, nothing. On the fifth she came back at the hour she would have come if she had never been away, and he read this to Ilaria down the phone in the voice of a man reporting that a cat has returned.

"She keeps her hour even when she is not here," he said.

"So does a star."

"So does a star," he agreed.

On the ninth, nothing again. The other nights, she came. Ilaria put the numbers into a spreadsheet on her phone, two columns: what Ettore measured, and what a star would have done. The columns separated slowly. At the end of the first week they were seventy seconds apart. At the end of the second, a hundred and forty. Ettore did not say anything about this on the phone, and Ilaria did not either. They talked about the weather on Velino, which had its first snow on the twelfth, and about the stove.

---

On the seventeenth of October she came up on the bus to Pescina and walked the last four kilometres, because her father needed the car. The road went up in a series of hairpins through the oaks, which were turning, and at every bend the plain opened out below her, flat as a table, ruled into strips of brown and green, with the great white dishes of the space centre standing in the middle of it like plates put out to dry. She had been told that the plain had been a lake until a prince drained it, a hundred and fifty years ago. Now it grew carrots, by the lorry-load. From up here you could not see a single carrot. You could see the order in which they had been planted.

The hut was warm when she arrived. Ettore had lit the stove before she came, which he had never done.

He did not show her the notebook at once. He made coffee in the little pot, two cups, and only after she had drunk hers did he push it across the table.

15/10 — 19:40:38 16/10 — 19:36:32

"Tonight," he said, "if I am a star, nineteen thirty-six exactly. You wrote it. I have not looked at the page since."

"If she comes."

"If she comes."

They waited. At nineteen twenty-five the line was not there. She watched the hydrogen breathing on the right of the screen, the soft wide band that had been there every time she had ever looked, and she thought that it was the only thing in the picture that would certainly be there tomorrow. At nineteen thirty a thin brightness appeared far on the left, at 1,381, and Ettore made a small sound with his tongue against his teeth.

She came up. She stood at her brightest. She went down. Ettore marked the top on the screen with the cursor, then moved it a little, then moved it back.

"Nineteen thirty-two twenty-seven," he said. "Give or take."

She turned to the back of the notebook. If star: 19:36:00. She did the subtraction in her head and then on the page, because he would want to see it on the page.

"Three minutes and thirty-three seconds early."

"Two hundred and thirteen seconds."

"Your error is ten."

He did not argue. He sat back in the chair and looked at the dish through the window. In the last of the light it was the colour of a pigeon.

"Twenty times my error," he said. "Then she is not a star." He said it plainly, the way he would have said that a cable was cut. "So what is she?"

Ilaria took the notebook and turned to a clean page. She had thought about this on the bus, and up the hairpins, and she had decided that she would not say anything she could not write down.

"She comes back every day," she said. "Not every star day. A bit less. Twenty-three hours, fifty-five minutes and fifty-four seconds, near enough. Something that goes round the Earth and comes back over us in the same place every day, but not quite. A satellite."

"I worked with satellites for thirty-one years," said Ettore. "My satellites did not come back every day. They never went away. They hung in the sky like lamps and I pointed the dish at them and that was the end of it. We called them the ladies." He put his finger on the window, at the empty south. "That is where they were. Thirty-six thousand kilometres up, going round exactly as fast as the Earth turns, so they stand still. If she were one of those, she would be on my screen all day and all night. She is on my screen for five minutes."

"So she goes round faster than the Earth turns. She goes round more than once a day."

"How many times?"

"Let us try twice," she said. "Twice is the simplest number that is not once."

She wrote the Moon at the top of the page, because the Moon was the one satellite she knew. Twenty-seven days and a third. Three hundred and eighty-four thousand kilometres. Kepler: the square of the time goes as the cube of the distance. A satellite going round twice a day takes half a day, about. Half a day over twenty-seven and a third is one over fifty-five, roughly, zero point zero one eight. Square it. Take the cube root. She did not have a calculator that did cube roots without fuss, and she did not want the fuss, so she guessed: seven hundredths, cubed, is three hundred and forty-three millionths, and the square of eighteen thousandths and a bit is a little under three hundred and thirty-five millionths. Seven hundredths, a shade under. So the satellite's orbit is seven hundredths of the Moon's.

"Twenty-six thousand seven hundred kilometres from the centre of the Earth," she said. "Take off the Earth, six thousand four hundred. Twenty thousand up. A bit more."

She looked up. He was not looking at the page. He was looking at the drawer.

"Twenty thousand," he said. "Twelve hours round." He opened the drawer and took out the black puck on its coil of cable and put it on the table between the cups. "Twenty thousand kilometres. That is where these talk to. The navigation. The Americans' clocks."

For a while neither of them said anything. Then Ettore laughed, once, not unkindly, at the puck.

"I bought a box to tell me what time it was," he said, "so that I would know exactly when the stars came. And it was her sister."

Ilaria picked up her phone and typed 1381 MHz into it, and read for a minute. Then she read it out, because she thought he would want to hear it exactly, and not from her.

"The GPS satellites carry a third channel. 1,381.05 megahertz. It is not for navigation. It is for the Nuclear Detonation Detection System. It is not on all the time."

Ettore said: "Say it again."

She said it again.

"So she is looking for flashes." He turned the puck over in his hand. On the bottom was a sticker with a serial number and the name of a shop in Pescara. "Every night she comes over the mountain and looks down at the Fucino to see if anybody has set it on fire. And she says so. Twenty-eight years I sit up here, and the only one who knocks is a satellite keeping watch for the end of the world."

"She doesn't knock for us," said Ilaria. "We were just in the way."

"Of course. Nobody knocks for us." He put the puck back in the drawer and shut it. "That is also information."

---

He did not want to stop. She had thought he might. She had thought, on the bus, of what she would say if he wanted to switch the receiver off and go down to his sister's for the winter, and she had not found anything. But he took the notebook and turned it to the front and wrote, in the square hand: 17/10. Signora identified. GPS, L3. Not a star. And under it, after a moment: Nineteen thirty-two twenty-seven. Twenty times the error.

"She will come tomorrow," he said, "at nineteen twenty-eight twenty-one, more or less, if she is switched on, and I do not need to see her. Help me with the handle."

The elevation drive had not been used since 1998. The motor had died a long time ago, but there was a hand crank for maintenance, and he had kept it greased, and he had kept the wire brush hanging next to it, and he had kept the brass collar polished, because he was the kind of man who did. Ilaria held the torch. He fitted the crank, braced his feet, and turned. Nothing. He turned again, and something in the gearbox let go with a crack like a branch, and the great dish began, very slowly, to lift.

He counted the turns aloud. Forty turns to the degree; she had seen it written inside the cover of the gearbox, in the same square hand, under a date in 1979. At eighty he stopped and leaned on the crank and breathed.

"Two degrees," he said. "Fifty-seven. She does not cross there. I hope."

"How do you know?"

"I don't." He took the crank off and hung it back on its nail. "We will look tomorrow. If she comes at nineteen twenty-eight, I was wrong, and I go up two more."

They went back inside. The stove had burned down and he fed it. On the screen the waterfall went on falling, pale and grainy, the hydrogen on the right as it always was, though the dish now looked at a strip of sky it had not looked at in twenty-eight years. On the left, at 1,381, there was nothing at all.

Ilaria turned to the back of the notebook, to her page, and under If not star: earlier, she wrote the date, and the time, and the word correct. Then she gave him back the pencil, and he put it in the jar.
