Bill Carter had been planning his bucket-list winter vacation to Alaska for 30 years, and he couldnt have picked a better time to take it.
The retired chemist from Jesup, Ga., didnt mind that February temperatures can hover near minus 40 degrees on the outskirts of Fairbanks, because the night sky there offered Carter something most people never get to see: the aurora borealis.
Yellows, oranges, greens. There were light bursts that would come from time to time, Carter said during his trip. There were light rays that seemed to come from the ground up, and from the sky down.
The northern lights can be seen on dark, clear nights when charged solar particles strike the upper atmosphere near the North Pole. Because of a predicted peak in a solar cycle, this year and next year are expected to offer prime viewing for the elusive phenomenon. So Alaskas tourism industry is gearing up for thousands of visitors like Carter including jetloads from Japan who are willing to wait outside in freezing weather, often for hours past midnight, in hopes of catching a once-in-a-lifetime glimpse of the lights.
Fairbanks, the largest city in Alaskas interior, is well-suited for aurora tourism because its just at the edge of the auroral oval, a ring-shaped region that circles the north magnetic pole where auroral activity is most common. It also has less cloud cover because of its distance from the ocean, and tourists usually can escape the citys light pollution by driving just 10 miles out. Lonely Planet, National Geographic and the Los Angeles Times travel section have all named Fairbanks or its surrounding areas as one of the best tourist destinations this year.
Dixie Burbank got a glimpse of the aurora as a child growing up in Wisconsin, but as an adult always wanted to travel to where the lights are more powerful.
This has been something Ive talked about for years, finally making our trek up to Alaska to see the northern lights, said Burbank, of Sun Prairie, Wis., who, like Carter, saw the lights during a visit to Alaska last month. Because of the solar max, this was the year to do it.
Solar cycles last about 10 or 11 years, and the solar max is the cycle peak, when the sun emits the most energy.
The heavens just opened up with activity, Burbank said. Its sheer excitement to see the lights come out.
When the solar cycle hit its low point or solar minimum in 2006, NASA predicted that the next solar maximum could produce the most activity since the historic solar max of 1958, when the northern lights could be seen as far south as Mexico. If you compound that with the fact that aurora activity tends to become more common around autumnal and vernal equinoxes, the start of spring this month could be quite hectic for Fairbanks.
Because of the buzz of the aurora blasts, we definitely think its gotten more attention from the media, said Deb Hickok, president and CEO of the Fairbanks Visitor Bureau and Convention Center. Its certainly been a busy winter.
Bernie Karl owns one of the most popular resorts in the Fairbanks area to see the lights. He said his Chena Hot Springs resort has been completely booked from the end of December to the end of March and all of next winter.
Todd Salat, a professional Alaska-based photographer who has been chasing the northern lights for 16 years, said he has seen some of the most powerful auroras of his career this winter and has taken some of his best photographs, too.
The thing just goes crazy and starts ripping across the sky, then all of a sudden, you cant believe what youre seeing ripples of light going from one horizon to the other in a matter of, you know, five or 10 seconds, Salat said. (Its) just incredible. It makes you feel small because its big. Its global.
But Salat and others who observe the aurora on a regular basis arent quite sure the predictions of increased activity will hold true based on what theyve seen so far this season.
Mark Conde, a professor of physics at the University of Alaska Fairbanks, expects that recent solar activity indicates auroras may not be as active this month as some have anticipated.
The current solar cycle is proving to be far less active than previous ones by quite a wide margin, Conde said. I would expect the peak of the current cycle if it follows the current trend we have now its probably going to only be about half as active as it was in 1958.
Despite Condes expectations, Fairbanks still expects to be inundated with tourists, especially from Japan. Japanese tourists have been traveling to see the lights for years, but the number of them traveling to the United States has risen significantly since Japan Airlines began chartering flights directly to Alaska almost a decade ago. The airline chartered 15 jets from cities throughout Japan to fly to Fairbanks this winter.
Shigeo Mori, who does Japanese marketing for Chena Hot Springs, explained that the Japanese fascination with northern lights stems from a philosophy that contemplates both sides of nature: its destructive power as well as its natural beauty.
Its more than a phenomenon for the Japanese people, Mori says. Its tradition; its history.
