"Friends of the Magnetosphere" Seminars

Below is a schedule of the informal LASP Friends of the Magnetosphere(FOM) Seminars for the Fall 2012 semester. LASP holds a series of informal seminars focused on space physics and plasma research relating to the magnetospheres of Earth and other planets.

The intended audience is space and planetary physics researchers in the Boulder area, although in most instances any interested persons are welcome to attend.

For more information or if you have questions, please contact Rob.Wilson at lasp.colorado.edu

View the Address and Directions page for detailed directions to any of the LASP locations.

November 27, 2012 – AGU Practice Talks

Speaker:   Various
Date:   Nov. 13, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

An opportunity for those with oral presentations at AGU to have a practice. If there are only a few takers then we’ll open it up to posters too. Karan Molaverdi

September 4, 2012 – “Charging of dust in the Enceladus plume: Limits on free electron depletion”

Speaker:   Frank Crary (LASP)
Date:   Sept. 4, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

In 2005, the Cassini spacecraft a large plume of water vapor emitted from the south pole region of Saturn’s moon, Enceladus. This plume adds approximately 100 kg/s of water molecules and ice particles to the Saturn system and produces an interacts with Saturn’s magnetosphere similar to the Io-Jupiter interaction. A key difference between Enceladus and […]

September 11, 2012 – “The Effect of Sudden Wind Shear on the Earth’s Magnetosphere”

Speaker:   Joe Borovsky (SSI)
Date:   Sept. 11, 2012
Time:   04:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

We have been looking at the properties of the solar wind at 1 AU and the physics of solar-wind/magnetosphere coupling. The solar-wind plasma is filled with wind shears. The velocity jumps across the shear layers can be Mach 1 or greater. Several times per day an abrupt wind shear passes the Earth. Global MHD simulations […]

September 25, 2012 – “Using frequency domain techniques in real-time space weather applications”

Speaker:   Jenn Gannon (USGS)
Date:   Sept. 25, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

The USGS Geomagnetism Program operates magnetic observatories across the United States, providing high quality, near real-time magnetic field measurements. These data support operational tasks, and are used as near real-time drivers to space weather models and indices. This presentation will discuss how frequency-domain techniques can be used in real-time to separate signals of interest, and […]

October 9, 2012 – “Electron scale structures and dynamics in thin boundary layers”

Speaker:   Cecilia Norgren (Uppsala)
Date:   Oct. 9, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

It is characteristic for many plasma environments in the Universe to form extended thin boundaries, separating regions of different kind of plasmas. Plasma processes at these boundaries are often of multiscale nature, coupling small electron scales and large magnetohydrodynamics scales, and may result in transport of energy and plasma, plasma energization and generation of plasma […]

October 16, 2012 – “Applying a Kalman Filter to Outer Radiation Belt Electrons”

Speaker:   Quintin Schiller (LASP)
Date:   Oct. 16, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

Data assimilation methods are becoming increasingly popular to describe the observationally sparse environment in Earth’s magnetosphere. As energetic electrons pose a number of hazards to manned and unmanned spacecraft, the outer radiation belts are an especially high profile candidate for data assimilation techniques. Energetic electron diffusion can be simplified with a Fokker-Plank equation, which also […]

October 23, 2012 – “Inward shift of outer radiation belt electrons as a function of Dst index and the influence of the solar wind on electron injections into the slot region”

Speaker:   Hong Zhao (LASP)
Date:   Oct. 23, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

The radial positioning of radiation belt electrons as a function of the Dst index and the controlling solar wind parameters for deep penetration of energetic electrons into the inner magnetosphere are investigated. Using 2-6 MeV electron data from SAMPEX satellite from Jan 1995 to June 2004, we examine the L location of energetic electron deepest […]

October 30, 2012 – “Fast Flow Channels and Ionospheric Joule Heating in the Cusp Region Under Non-Southward IMF”

Speaker:   Rick Wilder (LASP)
Date:   Oct. 30, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

We investigate fast plasma flows in the high-latitude cusp region during periods of extreme northward, dawnward, and duskward interplanetary magnetic field (IMF). During such periods, magnetic reconnection occurs near the cusp, leading to extreme energy deposition into the dayside ionosphere-thermosphere system. We use precipitating particle data from the DMSP spacecraft, as well as assimilation of […]

November 6, 2012 – “Rapid enhanced precipitation of radiation belt electrons: microbursts and precipitation bands”

Speaker:   Lauren Blum (LASP)
Date:   Nov. 6, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

We investigate rapid enhancements in energetic particle fluxes measured at low earth orbit by the SAMPEX satellite. Using high time resolution data from SAMPEX/HILT, enhanced precipitation of radiation belt electrons due to pitch-angle scattering is observed on a variety of timescales. Both the magnitudes and distributions of microbursts (~msec precipitation features), as well as longer […]

November 13, 2012 – “Ion acceleration observed by MEX”

Speaker:   Laila Andersson (LASP)
Date:   Nov. 13, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

This presentation will show ion observations below 2000 km from the MEX mission. The focus will be on bulk flows versus acceleration observations. The discussion will be mainly on what can be extracted and what is the limitations with this data set in the light of the MAVEN mission.
