History of Arapahoe County
History of Arapahoe County Arapahoe County was named for the Arapaho Indians, one of the In the late 1820s, trappers searched larger tribes of plains Indians, who along with the Cheyenne occupied this region for beavers to supply Arapahoe County east of the foothills running into what is now western the great demand for mens beaver Kansas. Arapahoe County is Colorado’s first county, since almost hats. In the late 1830s and 1840s, half of the entire area now Colorado was Arapahoe County of the the demand shifted to buffalo Kansas territory. In 1861, when Kansas was made a state, Colorado skins. In 1832, the first trading was made a territory with Arapahoe County as one of the 17 original post on the South Platte River was counties. built on Cherry Creek, which was then part of Arapahoe County. The original Arapahoe County was 30 miles wide and extended from Sheridan Boulevard, the present western boundary of Denver, Adams In 1848, gold prospectors on and Arapahoe counties to the Kansas border. This peculiar shape was their way to California stopped in due to the practice of giving counties with large amounts of plains Colorado long enough to pan its territory at least some of the foothill territory where there was water streams. They found gold on West for mining and irrigation. Even though Arapahoe County did not Dartmouth Avenue, just west of reach the foothills, the streams running from the mountains supplied Englewood where Dry Creek flows water.

Here, we describe the present state of knowledge with respect to such jets, which are a very common phenomenon downstream of the quasi-parallel bow shock. We discuss their properties as determined by satellite observations (based on both case and statistical studies), their occurrence, their relation to solar wind and foreshock con- ditions, and their interaction with and impact on the magnetosphere. As carriers of plasma and corresponding momentum, energy, and magnetic flux, jets bear some similarities to bursty bulk flows, which they are compared to. Based on our knowledge of jets in the near Earth environment, we discuss the expectations for jets occurring in other planetary and B F.

A Profile of Space Weather
A Profile of Space Weather Space weather describes the conditions in space that affect Earth and its technological systems. Space weather is a consequence of the behavior of the Sun, the nature of Earth’s magnetic field and atmosphere, and our location in the solar system. The active elements of space weather are particles, electromagnetic energy, and magnetic field, rather than the more commonly known weather contributors of water, temperature, and air. The Space Weather Prediction Center (SWPC) forecasts space weather to assist users in avoiding or mitigating severe space weather. Most disruptions caused by space weather storms affect technology, With the rising sophistication of our technologies, and the number of people that rely on this technology, vulnerability to space weather events has increased dramatically. Geomagnetic Storms Induced Currents in the atmosphere and on the ground Electric Power Grid systems suffer (black-outs) Pipelines carrying oil, for instance, can be damaged by the high currents. Electric Charges in Space Solar Radiation Storms Satellites may encounter problems with the on- board components and electronic systems. Hazard to Humans Geomagnetic disruption in the upper atmosphere High radiation hazard to astronauts HF (high frequency) radio interference Less threathening, but can effect high-flying aircraft at high latitudes Satellite navigation (like GPS receivers) may be degraded Damage to Satellites Satellites can slow and even change orbit. High-energy particles can render satellites useless (either temporarily or permanently) The Aurora can be seen in high latitudes Impact on Communications HF communications as well as Low Frequency Navigation Signals are susceptible to radiation storms. HF communication at high latitudes is often impossible for several days during radiation storms Space Weather Prediction Center The Space Weather Prediction Center (SWPC) Forecast Center is jointly operated by NOAA and the U.S. -
Lakewood, Colorado October 2013
Preliminary Feasibility Study Lakewood, Colorado October 2013 Prepared for SC SUSTAINABLE COMMUNITIES INITIATIVE DENVER REGIONAL COUNCIL OF GOVERNMENTS City of Lakewood 40 West Arts Denver Regional District Council of Governments ARTSPACE 250 Third Avenue N., Suite 500 Minneapolis, MN 55401 612.333.9012 www.artspace.org Introduction he City of Lakewood, Colorado, owes its name to a railroad man, W. A. H. Loveland, who platted its first lots in the 1880s. But it owes much of its mid-20th century T growth to America’s love of the automobile and the commercial activities that support the “love of the open road” lifestyle. Before the interstate system was built, U.S. Route 40 was the main drag between Denver and Salt Lake City, and it passed right through the heart of Lakewood on West Colfax Avenue. Although I-70 has supplanted U.S. 40 as the path of preference through the Rockies, West Colfax Avenue remains a major thoroughfare, and much of its historic character has survived. Indeed, to drive along West Looking west along Colfax Avenue in the late 1960s (Photo: Wikipedia Commons) Colfax Avenue today is to be reminded of an era when gas stations, roadside diners and indie motels were staples of the American landscape. But Lakewood itself has moved far past the 1950s. Today it has more than 140,000 residents and is the fifth largest city in Colorado, trailing only Denver, Colorado Springs, Aurora, and Fort Collins. A measure of its status is the new W light rail line, which opened earlier this year, connecting Union Station in downtown Denver to the Jefferson County Courthouse in Golden. -
The Magnetosphere-Ionosphere Observatory (MIO)
1 The Magnetosphere-Ionosphere Observatory (MIO) …a mission concept to answer the question “What Drives Auroral Arcs” ♥ Get inside the aurora in the magnetosphere ♥ Know you’re inside the aurora ♥ Measure critical gradients writeup by: Joe Borovsky Los Alamos National Laboratory [email protected] (505)667-8368 updated April 4, 2002 Abstract: The MIO mission concept involves a tight swarm of satellites in geosynchronous orbit that are magnetically connected to a ground-based observatory, with a satellite-based electron beam establishing the precise connection to the ionosphere. The aspect of this mission that enables it to solve the outstanding auroral problem is “being in the right place at the right time – and knowing it”. Each of the many auroral-arc-generator mechanisms that have been hypothesized has a characteristic gradient in the magnetosphere as its fingerprint. The MIO mission is focused on (1) getting inside the auroral generator in the magnetosphere, (2) knowing you are inside, and (3) measuring critical gradients inside the generator. The decisive gradient measurements are performed in the magnetosphere with satellite separations of 100’s of km. The magnetic footpoint of the swarm is marked in the ionosphere with an electron gun firing into the loss cone from one satellite. The beamspot is detected from the ground optically and/or by HF radar, and ground-based auroral imagers and radar provide the auroral context of the satellite swarm. With the satellites in geosynchronous orbit, a single ground observatory can spot the beam image and monitor the aurora, with full-time conjunctions between the satellites and the aurora.
