Explanation: Sometimes part of the Sun can just explode into space. These explosions might occur as powerful solar flares, coronal mass ejections, or comparatively tame eruptive solar prominences. Pictured above is one of the largest solar prominence eruptions yet observed, one associated with a subsequent coronal mass ejection. The prominence erupted last month and was recorded by several Sun-sensing instruments, including the recently launched Solar Dynamics Observatory (SDO). The above time lapse sequence was captured by SDO and occurred over a few hours. In recent months, our Sun has becoming increasingly active, following a few years of an unusually dormant solar minimum.
The International Association of Wildland Fire is planning the 11th Wildland Fire Safety Summit, to be held April 4-8, 2011 in Missoula, Montana. This year’s theme is “Promoting the Story of Wildland Fire Safety”, and highlights the importance of story and narrative in safety training, operations, research, and organizational learning.
The two-pager flyer for the Summit can be downloaded HERE. The first page of it is below.
Later in the year more information will be posted at the conference web site.
The National Fire Protection Association is accepting applications for their NFPA 1977 committee, Standard on Protective Clothing and Equipment for Wildland Fire Fighting. This is your chance to provide input on equipment you might be stuck with down the road. It is my understanding that you don’t have to be a member of the NFPA to serve on their committees.
These photos were taken Monday, May 3 in the Bigfork area, which is on Flathead Lake in northwest Montana. Over much of Montana on Monday and Tuesday they had some major winds that damaged trees, signs and trucks. The photos were taken by Rick Trembath of Flathead Forestry and Fire Consulting, a former Chief of the Bigfork Fire Department.
More information and photos of the extrication of the trees are below.
On May 10, 2000, a fire that began as a prescribed fire in Bandalier National Monument burned into Los Alamos, New Mexico. In its most extreme state on May 10, the Cerro Grande Prescribed Fire was carried by very high winds, with embers blowing a mile or more across the fire lines to the north, south, and east, entering Los Alamos Canyon towards Los Alamos, New Mexico. The towns of Los Alamos and White Rock were in the fire’s path and more than 18,000 residents were evacuated.
By the end of the day on May 10, the fire had burned 18,000 acres, destroyed 235 homes, and damaged many other structures. The fire also spread towards the Los Alamos National Laboratory, and although fires spotted onto the facility’s lands, all major structures were secured and no releases of radiation occurred.
The Cerro Grande Fire was the largest, most destructive wildfire that New Mexico has ever known. The fire swept across 47,000 forested acres in Bandelier National Monument, the Santa Fe National Forest, Los Alamos National Laboratory, Los Alamos County, and the Santa Clara and San Ildefonso Indian Reservations, causing about $1billion in property damage. Over 280 homes were destroyed or damaged and 40 Laboratory structures burned.
The fire had a major effect on prescribed fire operations nationwide. For more info.
