Magnetosphere Seminars

Check back soon for the Fall 2018 Semester Schedule.

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 any interested persons are welcome to attend.

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

Alfven Wave Propagation in a 3D Model of the Io Plasma Torus

Speaker:  Parker Hinton [APS]
Date & Time:  Tuesday, Nov 13, 2018 ,  4:00 pm
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

We use a combination of in situ plasma data (Voyager 1), physical chemistry, and Cassini UVIS observations to constrain a diffusive equilibrium model of the Io plasma torus (IPT) in three dimensions.

Magnetospheric Multiscale Observations of Magnetic Reconnection in the Earth’s Magnetosheath

Speaker:  Rick Wilder [LASP]
Date & Time:  Tuesday, Nov 06, 2018 ,  4:00
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

We will show several examples of diffusion region events observed in the magnetosheath, where the reconnecting magnetic fields have varying shear angles between them. We find that at low magnetic shear angle (anti-parallel reconnection), the electrons are agyrotropic, and the bulk of the energy conversion is due to electric fields and currents perpendicular to the background magnetic field.

Magnetic witches in your brain

Speaker:  Juan Roederer [University of Alaska]
Date & Time:  Tuesday, Oct 30, 2018 ,  4:00 pm
Location:  SPSC N100
Abstract:

The human brain is the only biological information system in the universe as we know it, that can willfully create “off-line” (i.e., without external information input in real time) images of non-existing things or never-experienced happenings, predict the long-term future of events, and make long-term plans (pet-owners: sorry, but this is an experimentally proven fact!)….

Jupiter is not Earth, Part II

Speaker:  Fran Bagenal [LASP]
Date & Time:  Tuesday, Oct 16, 2018 ,  4:00 pm
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

I hope to complete (ha!) my review of Juno results to date at the magnetosphere of Jupiter. In particular, I will focus on Jupiter’s intense aurora, what we are learning about processes that are similar to Earth – as well as important differences. One important difference is the role of the moons – particularly Io –… Read more »

MMS: Recent Results from Magnetotail

Speaker:  Robert Ergun [LASP]
Date & Time:  Tuesday, Oct 09, 2018 ,  4:00 pm
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

MMS has observed several electron and ion diffusion regions of magnetic reconnection in the Earth’s magnetotail. I will discuss what we know and what we do not know about magnetic reconnection in the Earth’s magnetotail.

Response Characteristics of the Ionosphere-Thermosphere System and Implications for Specification and Prediction

Speaker:  Eric Sutton [SWx-TREC]
Date & Time:  Tuesday, Oct 02, 2018 ,  4:00 pm
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

This talk will give an overview of recently developed data assimilation methods designed to accommodate the response characteristics of the I-T system while highlighting challenges, recent accomplishments, and expectations for improving I-T forecasting capabilities.

Solar rotation period driving of the plasmasphere

Speaker:  Scott Thaller [LASP]
Date & Time:  Tuesday, Sep 04, 2018 ,  4:00
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

Using Van Allen Probes data, we present the first in situ observations of convective processes in the inner-magnetosphere being driven at the solar rotation period (27 days) and harmonics.

Jupiter is not Earth: Latest from Juno

Speaker:  Fran Bagenal [LASP]
Date & Time:  Tuesday, Aug 28, 2018 ,  4:00
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

Juno is showing several surprises in the magnetosphere of Jupiter. This talk will survey these results from Juno and discuss their implications.

Using Electron Flux Oscillations as Indicators of ULF Wave Radial Diffusion

Speaker:  Theodore Sarris [Democritus University of Thrace​]
Date & Time:  Tuesday, Jul 17, 2018 ,  3:30 pm
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

We investigate the parameters affecting the appearance and amplitudes of 100s-keV electron flux oscillations, which appear under the effect of Ultra Low Frequency (ULF) fluctuations in the magnetosphere. To this direction, particle tracing simulations are conducted through a parametric study. It is found that the width in energy of electron energy channels are a critical… Read more »

Jupiter’s Magnetosphere is *now* seen by Juno JADE

Speaker:  Rob Wilson [LASP]
Date & Time:  Tuesday, May 08, 2018 ,  3:30 pm
Location:  LASP Space Science Building, room N100 (1st floor)
Abstract:

The at-launch mission plan of Juno barely allowed for exploration of the Jovian middle/outer magnetosphere, with only a narrow sliver of local time coverage to ~40Rj. However that plan has since changed, resulting in wide coverage over the proposed mission of 33 science orbits. Juno has completed a dozen perijove passes so far, with superb… Read more »
