Treble Cone near Lake Wanaka has ranked first in a survey out today by Australian magazine, Your Money, to find the best value ski area throughout Australia and New Zealand.
Comparing 11 major resorts in Australia and New Zealand, including packages and prices for peak season dates in July and August, each resort was given a score based on key attributes consumers look for when planning a trip to the snow. These included the cost of travel and accommodation, equipment hire, lift passes and quality of snow and terrain.
Treble Cone is scheduled to open on 23 June for the 2011 season. For further information, visit http://www.treblecone.com/ |

Be careful what you wish for... As just posted in the News section - sun spot activity is currently less than expected, and the sun may be about to enter a quiet period. The well-known "Maunder Minimum" (when very few sun spots were observed) lasted 70 years and coincided with the "Little Ice Age". Fancy a 70-year ski season??? :shock: :D :D :D |

The following Press Release was issued yesterday by scientists from the US National Solar Laboratory.
WHAT'S DOWN WITH THE SUN? MAJOR DROP IN SOLAR ACTIVITY PREDICTED A missing jet stream, fading spots, and slower activity near the poles say that our Sun is heading for a rest period even as it is acting up for the first time in years, according to scientists at the National Solar Observatory (NSO) and the Air Force Research Laboratory (AFRL). As the current sunspot cycle, Cycle 24, begins to ramp up toward maximum, independent studies of the solar interior, visible surface, and the corona indicate that the next 11-year solar sunspot cycle, Cycle 25, will be greatly reduced or may not happen at all.
Image courtesy of Wattsupwiththat - Average magnetic field strength in sunspot umbras has been steadily declining for over a decade. The trend includes sunspots from Cycles 22, 23, and (the current cycle) 24. The results were announced at the annual meeting of the Solar Physics Division of the American Astronomical Society, which is being held this week at New Mexico State University in Las Cruces: http://astronomy.nmsu.edu/SPD2011/
Spot numbers and other solar activity rise and fall about every 11 years, which is half of the Sun's 22-year magnetic interval since the Sun's magnetic poles reverse with each cycle. An immediate question is whether this slowdown presages a second Maunder Minimum, a 70-year period with virtually no sunspots during 1645-1715. Hill is the lead author on one of three papers on these results being presented this week. Using data from the Global Oscillation Network Group (GONG) of six observing stations around the world, the team translates surface pulsations caused by sound reverberating through the Sun into models of the internal structure. One of their discoveries is an east-west zonal wind flow inside the Sun, called the torsional oscillation, which starts at mid-latitudes and migrates towards the equator. The latitude of this wind stream matches the new spot formation in each cycle, and successfully predicted the late onset of the current Cycle 24.
In the second paper, Matt Penn and William Livingston see a long-term weakening trend in the strength of sunspots, and predict that by Cycle 25 magnetic fields erupting on the Sun will be so weak that few if any sunspots will be formed. Spots are formed when intense magnetic flux tubes erupt from the interior and keep cooled gas from circulating back to the interior. For typical sunspots this magnetism has a strength of 2,500 to 3,500 gauss (Earth's magnetic field is less than 1 gauss at the surface); the field must reach at least 1,500 gauss to form a dark spot. Using more than 13 years of sunspot data collected at the McMath-Pierce Telescope at Kitt Peak in Arizona, Penn and Livingston observed that the average field strength declined about 50 gauss per year during Cycle 23 and now in Cycle 24. They also observed that spot temperatures have risen exactly as expected for such changes in the magnetic field. If the trend continues, the field strength will drop below the 1,500 gauss threshold and spots will largely disappear as the magnetic field is no longer strong enough to overcome convective forces on the solar surface. Moving outward, Richard Altrock, manager of the Air Force's coronal research program at NSO's Sunspot, NM, facilities has observed a slowing of the "rush to the poles," the rapid poleward march of magnetic activity observed in the Sun's faint corona. Altrock used four decades of observations with NSO's 40-cm (16-inch) coronagraphic telescope at Sunspot. "A key thing to understand is that those wonderful, delicate coronal features are actually powerful, robust magnetic structures rooted in the interior of the Sun," Altrock explained. "Changes we see in the corona reflect changes deep inside the Sun." Altrock used a photometer to map iron heated to 2 million degrees C (3.6million F). Stripped of half of its electrons, it is easily concentrated by magnetism rising from the Sun. In a well-known pattern, new solar activity emerges first at about 70 degrees latitude at the start of a cycle, then towards the equator as the cycle ages. At the same time, the new magnetic fields push remnants of the older cycle as far as 85 degrees poleward.
All three of these lines of research to point to the familiar sunspot cycle shutting down for a while.
There's some interesting commentary on Wattsupwiththat. |

Darn. Just as I was about to offer the price of a coffee in Courchevel - €50 - a used lift pass from St.Anton and a single old ski sock...

Hmm, there's a shocker; Austrians wanting to keep hilly bits of Austria Austrian. Quite right. |
