"Friends of the Magnetosphere" Seminars

Below is a schedule of the informal LASP Friends of the Magnetosphere(FOM) Seminars for the Spring 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.


Full Schedule

February 28, 2012 – “Magnetic Reconnection Throughout the Heliosphere”

Speaker:   Mark Swisdak (University of Maryland)
Date:   February 28, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

Throughout the heliosphere magnetic reconnection facilitates the conversion of the energy stored in stressed magnetic fields into thermal energy, high-speed flows, and energetic particles. After first discussing the basic theory of reconnection and the role numerical simulations play in our current understanding of it, I will consider the effects of different plasma environments, including such […]

March 6, 2012 – “Investigating the mode structure of ULF waves in space and on the ground”

Speaker:   Theodore Sarris - (Democritus University, Greece)
Date:   March 6, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

Magnetospheric ULF (Ultra-Low Frequency) waves have frequencies in the mHz range, comparable with the drift frequency of high-energy particles, with which they resonantly interact. A critical parameter in this interaction is the azimuthal mode number of the waves, which determines the resonant condition for drift-resonant acceleration. We investigate the mode number and spatial extent of […]

March 13, 2012 – “Ions in magnetospheres of the outer planets: (Mis)interpretation of plasma data and non-unique interpretations”

Speaker:   Frank Crary, (SwRI)
Date:   Tuesday, March 13th
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

Abstract Pending

March 20, 2012 – “Upwelling to Outflowing Oxygen Ions at Auroral Latitudes during Quiet Times: Exploiting a New Satellite Database”

Speaker:   Rob Redmon (NOAA/NGDC)
Date:   March 20, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

The mechanisms by which thermal O+ escapes from the top of the ionosphere and into the magnetosphere are not fully understood even with 30 years of active research. A dynamic auroral boundary identification system has been developed using DMSP spacecraft observations at 850 km to build a database characterizing the oxygen source region. This database […]

April 3, 2012 – “Imaging in the Solar Wind”

Speaker:   Craig DeForest (SwRI, Boulder)
Date:   April 3, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

The vision for STEREO/SECCHI was to image solar wind phenomena continuously from their origin in the solar corona to interplanetary space. Analyzing these data is a challenge: the background star field accounts for 99.9% of the total intensity in the field of view of HI-2. However, with sophisticated post-processing techniques it is possible to separate […]

April 10, 2012 – “Magnetospheric substorm expansion and recovery phase features in Earth’s near- and mid-tail regions”

Speaker:   D.N. Baker (LASP)
Date:   April 10, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

The Cluster set of spacecraft in combination with other operating satellites are well-suited for the study of plasma sheet thinning and expansion associated with magnetospheric substorm dynamics in the Earth’s magnetotail. The Cluster orbital apogee of r=19 RE often places the spacecraft set in a very good location to be close to the substorm neutral line (reconnection) position. [...]

April 17, 2012 – “The Non-Linear Response of the Polar Cap Potential – New Questions”

Speaker:   Rick Wilder (LASP)
Date:   April 17, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

It is well known that the cross-polar cap potential (CPCP) exhibits a non-linear response to the interplanetary electric field. This response is commonly referred to as CPCP “saturation”. Using plasma convection data from the Super Dual Auroral Radar Network (SuperDARN) and the Defense Meteorological Satellite Program (DMSP), as well as statistical ionospheric conductance models, we […]

April 24, 2012 – “Field Aligned Currents in Saturn’s Middle Magnetosphere”

Speaker:   Licia Ray (Imperial College, London)
Date:   April 24, 2012
Time:   4:00 PM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

The Saturnian magnetosphere is a rapidly rotating system populated with neutral gas from Enceladus. Neutrals are ionized and picked-up by the planetary magnetic field and, outside of 6 Rs radially transported outwards through the magnetosphere. Field-aligned currents couple the magnetospheric plasma to the ionosphere, transferring angular momentum to the magnetospheric plasma. These upward currents are […]

July 9th, 2012 – “Unsolved issues of magnetospheric activity”

Speaker:   Bob McPherron (UCLA)
Date:   July 09, 2012
Time:   11:00 AM
Location:   LASP Space Science Building, room N248 upstairs. Map
Abstract:  

Abstract pending
