It was a fantastic
aurora; the best that anyone could recall in decades. When the September
18, 1941 Great Aurora took the stage, it was seen in Virginia, Denver
and St. Louis, but it was in New York City that it made itself distinctly
unwelcome. From Central Park at 9:30 PM, pedestrians could plainly see
several bright colored bands of light rivaling the full moon, in shades
of orange, blue and green. Curtains, rays and flashing displays of light
covered much of the sky throughout the rest of the night, giving New Yorkers
a taste of what their northern relatives in Alaska see on a weekly schedule.
The display had started before sunrise on Thursday, September 18 as thousands
of commuters got up and had breakfast before dealing with another New
York rush hour. This was a special day for other reasons as well. The
Brooklyn Dodgers would be playing the Pittsburg Pirates, and Red Barber
would be announcing the play-by-play activity over WOR radio. By 4:00
PM, the baseball teams were tied 0-0 when suddenly, and for an interminable
15 minutes, the broadcast on WOR radio was cut off by auroral interference.
When the broadcast resumed, the Pirates had scored four runs! Dodger fans
pounded the radio station switchboards by the thousands, hurling oaths
and bad language. The radio station tried to explain that they were absolutely
blameless, and that they should be cursing the auroral displays over their
heads. Apparently calm reasoning did little good. No one really bought
the idea that solar storms had raided the game.
NBC, meanwhile,
was busy trying to resolve their own problems. They were scheduled to
do a special inaugural broadcast to Mexico to open 23 new affiliate radio
stations. Although the program could be easily heard in the United States,
in Mexico the static and interference made the reception of the program
impossible, although north-directed broadcasts from Mexico to the United
States could be heard. Throughout most of Thursday, NBC and CBS short-wave
transmissions were badly interrupted just about everywhere. RCA could
no longer make connections with London directly, but they discovered that
a new channel had opened up instead. By transmitting to Buenos Aires and
then having the signal relayed to London along a 12,000-mile path, they
could get a connection that was actually clearer than along the direct
route. But the aurora were not quite finished with New York
The next day,
after dazzling aurora washed the skies the evening before, New Yorkers
were treated to a second amusing incident. At 11:45 AM, WAAT in New Jersey
was broadcasting recorded songs by Bing Crosby when a conversation between
two men interfered with portions of the music. Station engineers worked
frantically to clear up the cross-talk problem but there wasn't a whole
lot they could do. Within a few minutes, the voices just as mysteriously
disappeared, but not before callers from New Jersey complained by the
hundreds on the station's switchboards.
No sooner
had this problem solved itself when the noon news broadcast was interrupted
by a much louder conversation between two women. This time the discussion
was about their blind dates, and the language they used was euphemistically
noted by the newspapers as 'spicy'. Again, the auroral conditions overhead
had mixed a short-wave channel with the normal broadcast at nearly the
same frequency. Many callers complained about the change in programming,
which was being heard by young children. There were even a number of men
who called WAAT to inquire about the women during this aurora-moderated
dating hotline.
Because aurora,
and the powerful electromagnetic forces that cause them, have a strong
affinity for all things electrical, it is not surprising in retrospect,
that every communications technology we have erected in the last 160 years
has fallen victim to interference from these natural events.
Electrical
currents were magical in many of the ways that they worked. For example,
in 1820, Hans Oerstead a physicist at the University of Copenhagen could
make electrical currents deflect compass needles. Meanwhile, across the
English Channel, Michael Faraday uncovered an equally mysterious electrical
phenomenon: If you move a magnet across a wire, it causes a current to
flow in the wire. It's hard to imagine the excitement these investigators
must have felt as they saw electrical currents produce invisible magnetic
forces and vice versa. Faraday's discovery of changing magnetic fields
producing electrical currents, combined with Alexander von Humbolt's discovery
that sudden changes in the Earth's magnetism can occur in 'magnetic storms',
provided the ingredients for an interesting natural experiment. All that
was needed was a network of wires large enough to catch nature in the
act of inducing currents. The 30,000 mile long telegraph network available
in 1848 provided just the right technology for the experiment, and during
the next few years, telegraphists caught much more that simply the dits
and dahs they had bargained for. For a long time they had no clue what
was going on in their wires.
During the
aurora of November 17, 1848, the clicker of the telegraph connecting Florence
and Piza remained stuck together as though it had become magnetized, even
though the receiving apparatus was not in action at the time. This could
only happen if an electric current from some outside source had flowed
through the wires to energize the electromagnet. Telegraphers elsewhere
also began to notice that their lines mysteriously picked up large voltages
that caused their equipment to chatter as well, with no signal being sent.
Much of this was soon attributed to the long wires picking up lightning
discharges in their vicinity, and the solution was simply to erect lighting
rods on the telegraph poles. American telegraphists had only a short time
to puzzle over atmospheric electricity on their 1000-mile lines when in
1859, the Great Auroras of August 28 and September 4 blazed forth and
lit up the skies of nearly every major city on the planet. It was one
of the most remarkable displays ever seen in the United States up until
that time, and its effects were simply wonderful.
These aurora
were so exceptional that the American Journal of Science and Arts
published no fewer than 158 accounts from around the world describing
what the display looked like, the telegraphic disruptions they produced,
and assorted theoretical speculations. Normal business transactions requiring
telegraphic exchanges were completely shut down in the major world capitals.
In France, telegraphic connections were disrupted as sparks literally
flew from the long transmission lines. There were even some near-electrocutions.
In one instance, Fredrick Royce a telegraph operator in Washington D.C
reported that,
"During the
auroral display, I was calling Richmond, and had one hand on the iron
plate. Happening to lean towards the sounder, which is against the wall,
my forehead grazed a ground wire. Immediately I received a very severe
electric shock, which stunned me for an instant. An old man who was sitting
facing me, and but a few feet distant, said he saw a spark of fire jump
from my forehead to the shoulder. "
While a silent
battle was being waged between telegraphists and aurora, Alexander Graham
Bell, in 1871, uttered the first telephonic sentence in his laboratory
"Mr. Watson, come here. I want you". In less than a year, the first
toll-free, long-distance phone call was placed by Watson and Bell, between
Cambridgeport and Boston, using borrowed telegraph lines. Meanwhile, as
if to celebrate this event, the Great Aurora of February 4, 1872 colored
the skies. Again, reports could be found in the newspapers and science
journals of powerful voltages induced upon telegraph lines. During the
November 17, 1882 Great Aurora, the telephone lines of the Metropolitan
Telephone Company refused to work until after 2:00PM. Disruptions were
also reported on the cables to Cuba and Mexico. The Chicago stock market
was severely affected all day. By the time impacts were identified, it
was already far too late to rethink the deployment of the technology.
The impact that solar storms had on telegraph, telephone, and power lines
was truly unexpected. By the time the famous September 1859 storm had
lashed the Earth, telegraphy had already become a transcontinental reality,
displacing the Pony Express with 30,000 miles of line strung up on trees
and poles. Telephony was born 19 years later, but it took another 11 years
for its vulnerability to be tested during the November 18, 1882 solar
storm.
By 1901 there
were over 855,000 telephones in service in the 'Bell Telephone System'.
It seemed as though the telephone industry had taken the country, and
the world, by storm. Everyone wanted their own private line, and the only
limiting factor in the spread of this technology was how quickly the Bell
Telephone Company could cut down trees to make telephone poles, and wire
your city block or town into the growing national circuitry. Today, the
same public urgency exists in the cellular telephone market. Everyone
wants their own cellular phone, and telecommunications companies can't
launch satellites fast enough to keep up with the demand.
No sooner
had some considerable money been spent on wiring the world for telegraph
and telephone, but a still newer technology appeared in full bloom from
literally out of nowhere. Guillermo 'William' Marconi in 1895 tinkered
together the first spark gap radio wave transmitter and receiver in the
garden of his father's estate. Instead of transmitting and receiving electrons
flowing in a wire, it was the 'wireless' emission and reception of electromagnetic
radiation that carried the messages. By 1905, there were over 100 wireless
telegraph transmitters in the US with transmission ranges of 500 miles.
There were also some seven million telephones in service on the same wires
that once carried telegraphic messages.
So what did
people do with this new technology? Many people sure didn't use it very
responsibly. Unlike the telephone or telegraph where the ends of the lines
are geographically known, for wireless broadcasts, everyone is anonymous
unless they choose to identify themselves. As Historian Edward Herron
wrote in Miracle of the Air Waves: A history of radio
"..[Amateurs]
thrilled to calls for help from sinking ships...and were not above creating
synthetic excitement...sending out false messages that caused international
distress, confusion, and waste of time and resources...Commercial stations
depending on the dollar revenue from the dots and dashes, were constantly
at war with the amateurs who rode ruthlessly into the same wavelengths,
causing havoc with the commercial messages."
This forerunner
to modern computer 'hacking' was the main reason why the US Government
had to step in and put an end to the unruly amateur broadcasts in 1917.
Once World War I had concluded in 1919, the embargo was lifted, and the
pace of radio technology research exploded like champagne out of a bottle.
The first commercial radio station, KDKA, owned by Westinghouse opened
for business on November 2, 1920 to a hungry crowd of over 30,000 amateur
wireless operators who had cobbled together their receivers as home hobbyists.
Two years later, there were 1.5 million sets in use, and by the end of
the decade there were radio sets in 7,500,000 homes. This phenomenon had
taken eight years to escalate to this level, while telephone service took
37 years to reach the same number of homes. Today's stampede of people
onto the Internet is only the most recent of many waves of colonization
of new high-tech niches that have opened up during this century.
Most of the
broadcasting during the 1920's was done at long wavelengths, but by 1925
the Navy got involved with short-wave broadcasting because it could be
received long distances with little interference, and could also be transmitted
during the daytime, unlike the then-popular long wave transmissions. Wars
are fought day and night, so there was tremendous pressure to push transmission
technology to higher frequencies and shorter wavelengths where daytime
'bounce' was possible. Ironically, the short-wave radio frequencies would
drive communication into the very domain that made then a victim of solar
interference. Now, whenever aurora dominated the sky, and the Sun was
throwing out flares like electromagnetic thunderbolts, their impacts would
appear in many different guises, and across the entire spectrum of communications
technology. By the time that solar cycle 17 began in 1933, 23 million
homes (70% of total homes) had short-wave radio receivers, and Americans
listened to nearly one billion hours each week of broadcasting. Television
receivers operating in the newly conquered megacycle radio spectrum were
already being field tested by several manufacturers and were expected
to be available to the consumer within a few years. Short-wave interruptions
were an increasingly common annoyance during daytime broadcasting, but
their origins in distant solar flares were not recognized until 1937.
The Great
Aurora of January 1938, March 1940, and February 1956 were seen in Europe
and as far south as Sicily. British citizens in 1938 were dazzled by the
biggest display they had seen in 50 years and thought London was aflame.
Crowds in Vienna awaiting the birth of Princess Juliana's baby cheered
the January aurora as a lucky omen. Millions of Easter Sunday calls to
Grandma in 1940 were halted between 10:00AM and 4:00PM on March 24. Even
the Executive Curator of the Hayden Planetarium, William Barton, had to
go on a nation-wide radio hookup to explain what was going on. The February
1956 Great Aurora included one of the most intense blasts of cosmic rays
ever recorded by scientists up until that time. But while scientists and
the public were being dazzled above ground, a far more urgent series of
events was unfolding beneath the sea. A full-scale naval alarm had been
raised for a British submarine, which was thought to have disappeared.
The Acheron had been expected to report her position at 5:05 EST while
on Arctic patrol. When it failed to do so, emergency rescue preparations
were begun. Ships and rescue planes began the grim task of searching the
deadly, ice cold waters between Iceland and Greenland, but no trace of
flotsam or jetsam from the sub was ever seen. Then, the 'missing' submarine
turned up four hours later when its transmissions were again picked up.
The February
10, 1958 Great Aurora colored the skies over Chicago and Boston in a dramatic
spectacle that punctuated more earthly events. A terrible snow storm had
paralyzed upstate New York, and another Redstone rocket had just been
launched by the U.S Army. In a foretaste of what would become a common,
and expensive, problem decades later, the Explorer 1 satellite launched
two weeks earlier, suddenly lost its primary radio system. The geomagnetic
activity knocked out telecommunications circuits all across Canada, and
although it was not visible in the New York area, it was so brilliant
over Europe it aroused fears of conflagrations. The Monday storm cut-off
the United States from radio contact with the rest of the world following
an afternoon of 'jumpy connections' that ended with a complete black out
by 3:00 PM, although contact with South America seemed unaffected. By
evening, radio messages to Europe could occasionally be sent and received.
Radio and
TV viewers in the Boston area, however, were reportedly having their own
amusing problems. For three hours, they fiddled with their TVs and radios
as their sets went haywire, at times blanking out entirely, or changing
stations erratically. Channel 7 viewers began getting Channel 7 broadcasts
from Manchester Vermont, while Channel 4 viewers received ghostly blends
of the local Boston station and one in Providence, Rhode Island. Viewers
had just finished watching the 'Lawrence Welk Show' at 9:30 PM and were
preparing to watch a nationally-broadcast TV movie 'Meeting in Paris'
on Channel 4, or listen to a boxing match. What they hadn't counted on
was that they would get to do both at the same time. Jane Greer played
the ex-wife who asks her former spouse, played by Rory Calhoon, to smuggle
her new husband out of France. Instead, they discover '...that the old
spark is still alive when the have a strange encounter in Paris'. During
a passionate love scene, the audio portion of the movie was replaced by
the blow-by-blow details of the boxing match:
"Smith
gave him a left to the jaw and a short right hook to the button.
But
darling we love each other so much.
A
left hook to the jaw flattened Smith and he's down for the count.
Kiss me
again my sweet."
The newspapers
prior to 1958 made frequent mention of short-wave problems coinciding
with aurora and magnetic storms. Often these problems were announced in
banner headlines on page one. Today, we seldom hear of telephone or short-wave
interruptions making any impact on us, at least not the way they used
to. But yesterday's communications mishaps are only the preludes to even
wider, and more insidious, problems we now have to deal with in the most
recent decade
