She clicked her mouse。 Another screen came up。 〃Oh; wait; here's another one。 There it is;〃 she said。
It filled half the screen。
An enormous yellow…white blob of atmospheric disturbance。 It filled the entire left…hand side of the map; smothering nearly half of the pictured Antarctic coastline。 In real terms; Schofield thought; the solar flare must have been absolutely enormous。
〃And that is your solar flare; Lieutenant;〃 Abby said。 She turned to look at Schofield。 〃It must have moved eastward after this shot was taken and covered us; too。〃
Schofield stared at the yellow…white blob superimposed on the Antarctic coastline。 There were slight discolorations in it; red and orange patches; even some black ones。
Abby said; 〃Since they usually explode in one section of the sun's surface; solar flares usually only affect defined areas。 One station might have a total radio blackout while another; two hundred miles away; will have all of its systems working just fine。〃
Schofield stared at the screen。 〃How long do they last?〃
Abby shrugged。 〃A day。 Sometimes two。 However long it takes for all the radiation to make the trip from the sun to the Earth。 Depends on how large the original sunspot was。〃
〃How long will this one last?〃
Abby turned back to face her puter。 She looked at the depiction of the solar flare on the screen; pursed her lips in thought。
〃I don't know。 It's a big one。 I'd say about five days;〃 she said。
A short silence followed as what she said sank in to everyone in the room。
〃Five days;〃 Rebound breathed from behind Schofield。
Schofield was frowning in thought。 Abby: 〃You say it disrupts the ionosphere; right?〃
〃Right。〃
〃And the ionosphere is 。。。〃
〃The layer of the Earth's atmosphere about 50 to 250 miles up;〃 Abby said。 〃It's called the ionosphere because the air in it is filled with ionized molecules。〃
Schofield said; 〃OK。 So; a solar flare explodes on the surface of the sun and the energy it emits travels down to Earth; where it disrupts the ionosphere; which turns into a shield through which radio signals can't pass; right?〃
〃Right。〃
Schofield looked at the screen again and stared at the black splotches on the yellow…white graphic representation of the solar flare。 There was one larger black hole in the middle of the yellow…white blob that held his attention。
〃Is it uniform?〃 he asked。
〃Uniform?〃 Abby blinked; not prehending。
〃Is the shield uniform in its strength? Or does it have weak points; inconsistencies; breaks in the shield that could be penetrated by radio signals? Like these black spots here。〃
Abby said; 〃It would be possible to penetrate them; but it would be difficult。 The break in the flare would have to be directly over this station。〃
〃Uh…huh;〃 Schofield said。 〃Is there any way that you could figure out when or if one of those breaks would be directly over us? Like; maybe; this one here。〃
Schofield pointed at the large black hole in the center of the yellow…white blob。
Abby studied the screen; evaluated the possibilities。
Finally; she said; 〃There might be a way。 If I can bring up some previous images of the flare; I should be able to plot how fast it's traveling across the continent and in what direction。 If I can do that; then I should be able to make a rough plot of its course。〃
〃Just do what you can;〃 Schofield said; 〃and call me if you find anything。 I want to know when one of those breaks is going to pass over this station; so we can be ready to send a radio signal to McMurdo when it does。〃
〃You'll have to fix the antenna outside…〃
〃I'm already on it;〃 Schofield said。 〃You just find me a break in that flare。 We'll get your antenna up again。〃
In Washington; Alison Cameron was also sitting in front of a puter。
She was in a small puter lab in the Post's offices。 A microcrofilm viewing machine sat in the corner。 Filing cabinets lined two of the four walls。 Half a dozen puters filled the rest of the space in the small lab。
Alison found the screen she was looking for。 The All…States Library Database。
There is a popular urban myth that the FBI has a tap on every library borrowing puter in the country and they use this facility to track down serial killers。 The killer quotes Lowell at a homicide scene; so the FBI checks up on every library in the country to see who's been borrowing Lowell。 Like all good urban myths; this is only a half…truth。 There is a system (it is an updatable CD…ROM service) that cross…links every library puter in the country; telling the user where a certain book can be found。 It doesn't list the names of every person who has borrowed that book。 It just tells you where a particular book is located。 You can search for a book in several ways: by the author; by the book's title; or even by any unusual keywords that appear in the text of a book。 The All…States Library Database was one such service。
Alison stared at the screen in front of her。 She tabbed down to the SEARCH BY KEYWORD button。 She typed:
ANTARCTICA。
The puter whirred for about ten seconds; and the results of the search came up on the screen:
1;856;157 ENTRIES FOUND。 WOULD YOU LIKE TO SEE A LIST?
Great。 One million; eight hundred and fifty thousand books contained the word Antarctica in some way or another。 That was no help。
Alison thought for a second。 She'd need a narrower key word; something a lot more specific。 She got an idea。 It was a long shot; perhaps a little too specific。 But she thought it was worth a try anyway。 She typed:
LATITUDE …66。5° LONGITUDE 115° 20' 12〃
The puter whirred as it searched。 This time the search didn't take long at all。 The results came up on the screen:
6 ENTRIES FOUND。 WOULD YOU LIKE TO SEE A LIST?
〃You bet your ass I'd like to see a list;〃 Alison said。 She hit the 〃Y〃 key for 〃Yes〃 and a new screen appeared。 On it was a list of book titles and their locations。

Alison stared at the list。
Every one of these entries; in some way or another; mentioned latitude minus 66。5 degrees and longitude 115 degrees; 20 minutes; and 12 seconds。
They were mainly university papers。 None of the names meant anything to Alison: Llewellyn; Austin; and the two Hensleighs; S and B。
It looked like the latter Hensleigh…B。 M。 Hensleigh…had written a book on Antarctica。 Alison looked at its location reference。 It had been printed at Harvard University; but it was available at AML…all major libraries。 Unlike all of the other entries…a collection of single…issue privately published theses…this Hensleigh guy's book was videly available。 Alison decided she'd check it out。
There was; however; one other entry that caught her attention。
The last one。
PRELIMINARY SURVEYWAITZKIN; C。 M。LIBCONG1978
Alison frowned at the final entry。 She checked a quick reference list that was affixed to the side of the puter monitor。 It was a list of all of the abbreviations used in the database。 Alison found 〃LibCong。〃
〃Aha;〃 she said aloud。
LibCong stood for the Library of Congress。 The Library of Congress was situated across the road from the Capitol Building; not far from Alison's office。
Alison looked at the final entry again。 She wondered what a preliminary survey was。 She looked at the date of the entry。
1978。
Well; whatever it was; it was over twenty years old; so it was worth checking out。
Alison smiled as she hit the button marked: PRINT SCREEN。
〃All right! Hoist her up!〃 Book called。
Rebound and Snake pulled on the stabilizing cables; and Wilkes Ice Station's battered radio antenna…a long black pole thirty feet high; with a…blinking green beacon light at its tip…rose slowly into the air。 The intermittent flash…flash of the green beacon light illuminated all of their faces。
〃How long do you think it will take?〃 Schofield asked Book; yelling above the wind。
〃It won't take us long to hoist it up; that's the easy part;〃 Book replied。 〃The hard part will be reconnecting all the radio wiring。 We've got the power going again; but there's still another fifteen or so radio wires to solder back together。〃
〃Ballpark?〃
〃Thirty minutes。〃
〃Get to it。〃
Shane Schofield trudged back down the entrance ramp of the station and headed inside。 He had e back inside to check on two things: Abby Sinclair and Mother。
Abby met him on the A…deck catwalk。 While Schofield and the others had been outside; she had been in the radio room looking at weather maps on the puter; trying to find a break in the solar flare。
〃Any luck?〃 Schofield asked。
〃Depends on what you mean by luck;〃 Abby said。 〃How soon did you want it?〃
〃Soon。〃
〃Then I'm afraid it's not that good;〃 she said。 〃By my calculations; a break in the solar flare will pass over this station in about sixty…five minutes。〃
〃Sixty…five minutes;〃 Schofield said。 〃How long will it last?〃
Abby shrugged。 'Ten minutes。 Maybe fifteen。 Long enough to get a signal through。〃
Schofield bit his lip as he took all of this in。 He had been hoping to get a window in the solar flare a lot sooner than that。 He desperately needed to get in contact with McMurdo Station to tell them about the French warship that was sailing off the coast of Antarctica aiming a battery of missiles at Wilkes Ice Station。
He asked; 〃Will there be any more breaks ing over the station?〃
Abby smiled。 〃I thought you'd ask that; so I checked it out。 There will be two more breaks in the flare after the first one; but there's a long wait for them。 OK。 The time is now 2:46 p。m。 so the first w
