Calgary defenceman Eric Frere gloves down Derek Hulak’s shot in the first overtime period.
Ward wins it in triple overtime Huskies crowned Canada West champions KEVIN MENZ Sports Editor Brett Ward doesn’t always score goals, but when he does he makes sure they are game winners in triple overtime. Ward’s shot from the point in the sixth period of the third and deciding game of the Canada West final March 11 at Rutherford Rink found its way through screened University of Calgary Dinos netminder Dustin Butler’s pads and pushed the University of Saskatchewan Huskies to a 2-1 win and their first conference title since 2007. “I definitely just threw it at the net and didn’t know where it was going,” said a breathless Ward after the 106-minute and 33-second
affair — the longest in Canada West history. “Thank God it went in.” The third-year Huskies defenceman only scored one goal throughout the entire regular season but has already tripled that number in this year’s playoffs. He said that, as a defenceman, he was more focused on preventing the sudden-death winner than he was on scoring it and that being the hero was just a bonus. “I definitely haven’t scored the winner in a game like this before,” said Ward. The goal and the 2-1 series win over the Dinos lands Saskatchewan a spot at the University Cup, played March 22-25 in Fredericton, N.B. It’s the Huskies’ first appearance at the national
championship since 2008. “We have nine or 10 days here, so we’ll definitely celebrate a bit,” said Huskies goaltender Ryan Holfeld. “Then we’ll get back on track before we head out east.” Holfeld, who stopped 38 of 39 shots in the game, matched Butler save-for-save in the overtime periods and, ultimately, got the best of the Calgary netminder. While Holfeld highlighted the extra frames with his quick pads, no save was more important than his slide across the crease with only five minutes remaining in the fifth period. Hockey cont. on

A blast of energetic particles from the sun collided with Earth March 8, causing disruptions in all four of the University of Saskatchewan’s SuperDARN radars. SuperDARN, or Super Dual Auroral Radar Network, is an international system of over 20 radars operating together and looking into the polar regions of the Earth. The U of S controls four SuperDARN radars: one in Saskatoon, one in Prince George, B.C. and two in the arctic. “All of our radars in the last day or two have been receiving no data, they’ve been blacked out,” Kathryn McWilliams said a day after the network went down. She is a U of S physics professor who analyzes the radar network. The blackouts were due to the largest solar storm to hit Earth since 2006, McWilliams said. Earlier in the week, a pair of explosions on the sun’s surface sent massive clouds of particles — resembling bubbles — racing outward into space. “We just happened to be in the path of this thing,” McWilliams said. As the storm reached Earth, the particles interacted with the upper atmosphere and the magnetic field, leading to reports of auroral activity moving from the North
Pole to Canada and dipping into the northern United States. But McWilliams said the magnetic activity can also result in damaged power grids and cause GPS systems to misalign. “I believe GPS was probably quite strongly affected,” McWilliams said. “The communications between [satellites] and the ground have to go through the atmosphere, so when the storm is enhanced, radio waves tend to bend a bit more so your position is off.” Explosions on the sun, or solar flares, gradually increase in 11-year cycles. At peak level, Earth will absorb two or three solar storms per year. The last peak period was in 2001 or 2002, McWilliams said. “We should be getting more of these things happening as it has been unusually quiet even though we are getting close to the maximum activity period.” The SuperDARN radar system allows scientists to capture largescale voltage readings from miles above the surface to examine what happens when solar wind reaches Earth’s atmosphere. “We’re trying to understand the physics of the coupling between the solar wind, the Earth’s magnetic fields and the upper atmosphere,” said McWilliams. “Unfortunately, this time, because of the operational problems, we couldn't see anything.”
