TORSHAVN, Faeroe Islands (AP) -- For months, even years, hotels on the remote Faeroe Islands have been fully booked by fans who don't want to miss an almost three-minute-long astronomical sensation. Now the sky gazers just hope the clouds will blow away so they can fully experience Friday's total solar eclipse.

Scores of eclipse chasers and scientists have invaded the archipelago armed with telescopes, cameras and glasses for safe direct solar viewing ahead of the big event.

The weather forecast is better 1,200 miles to the northeast, in the Arctic islands of Svalbard, where spectators can hope for a clear day. The full eclipse will only be seen in a narrow path across the northern hemisphere, reaching the Faeroes at 0945 GMT (2:45 a.m. PDT) on Friday.

"This is our 10th total eclipse. We love to watch them and being able to look at the corona with your eyes in the middle of the eclipse is really an exciting moment, to experience the diamond rings coming and going," said Les Anderson, a 60-year-old from San Diego, California, in the Faeroe capital of Torshavn.

The population of the 18 rocky islands between Scotland and Iceland has swelled by approximately 10,000 for a few days from its usual 48,000 souls.

"There has never, never been so many people on the islands before," said Theresa Kreutzmann, head of the tourism office in Torshavn.

The two best places to fully experience the total solar eclipse are the Faeroes, where the moon covers the sun completely for 2 minutes 45 seconds, and Svalbard, more than 800 kilometers (500 miles) north of the Norwegian mainland, where it will be 15 seconds shorter.

A partial solar eclipse can be seen across Europe and parts of Asia and Africa. Britain's Meteorological Office says 95 percent of the sun will be covered in the Hebrides, Orkneys and Shetland Islands.

Although Faeroe camping sites have opened ahead of time for those willing to brave nighttime temperatures of around 1.5 degrees Celsius (35 degrees Fahrenheit), authorities on Svalbard have reminded last-minute visitors that bringing a sleeping bag and finding a cozy corner for the night is not an option. The thermometer there hovers around minus 15 degrees Celsius (5 degrees Fahrenheit). And then there are the polar bears, which roam freely -- meaning that people need to carry firearms when moving outside settlements.

On average, three bears are shot in self-defense every year on Svalbard with an estimated polar bear population of 3,000 -- roughly the same as the human population. Visitors have been attacked. Just Thursday, a bear attacked a tent in which a Czech tourist was sleeping, slightly injuring him. In 2011, a British teenager was fatally mauled by a bear that attacked the tent he was sleeping in.
