After a 65-day disappearance, the sun reappeared at the top of Alaska, but the cold yellow disk sitting on the southern horizon failed to heat temperatures out of the subzero double-digit deep freeze. Barrow was 28 degrees below zero when the sun struggled over the horizon at 1:09 p.m. for a 61-minute game of peekaboo behind pink clouds before setting. Restaurants in Barrow celebrated with sunrise lunch specials. In the interior of Alaska, some towns were reporting high temperatures in the minus-50 to minus-65 range and were shivering into a second week of extreme cold, the National Weather Service said. “The daytime highs have little meaning because there is still no significant sunlight this far north,” Fairbanks meteorologist Ted Fathauer said.
