POETRY, Taylor |
I will describe our current and future POETRY projects and
progress. There will also be several new products to show,
including the complete Blackout! product, a new CD, a new
litho set, the Space Weather Center, the Northern Lights
Poster which is in progress, and, Force 5, a new
planetarium show, which is also in work.
|
Brief review IMAGE FUV in flight Calibration, Mende |
A review of progress on what quantitative numbers one
can deduct from FUV measurments.
|
RPI data availability and visualization, Galkin |
RPI data analysis tools now feature a database of expert
ratings that allows searching for the measurements of a
particular scientific content. The technique might be of
interest to the IMAGE team scientists and data managers.
|
Pitch-angle distributions of the storm-time ring current, Brandt |
Date: 24-26 May 2000. We see significant effects of varying
PAD as a function of MLT. Knowledge of the PADs are
essential to do proper forward modeling of the ion
distribution. We propose a mechanism for developing the PADs
we see, which involves interaction between ring current and
plasmasphere.
|
Simultaneous ENA observations of ring current injection from IMAGE and Polar, Henderson |
This study examines data from the Oct 4-6, 2000 storm. We
will discuss correlations between the ENA images (MENA and
HENA) and in situ measurements from the LANL geosynchronous
satellites. We also discuss first steps toward image
inversion to determine ion distributions.

Importance of energetic neutral atom emission from the exosphere: IMAGE/HENA, Roelof |
A discussion of non-geocorona dominated ENA emission at low
altitudes as seen by HENA will be presented.
|
Upper limits on intensities of energetic 1-100 keV neutral hydrogen atoms generated beyond the heliospheric termination shock: Measurements from IMAGE/HENA/MENA, Roelof |
Energetic neutral hydrogen atoms generated in the vicinity
of the heliospheric termination shock can provide significant
diagnostics of the pre-shock and post-shock plasma conditions.
|
RPI Observations of plasmaspheric ducted echoes, Fung |
Examples and interpretation of ducted echoes observed by
RPI at altitudes of a few Earth radii will be presented.
|
Precipitation into the cusp (two coordinated talks), Fuselier/Frey |
FUV observed several cases of strong precipitation into the
cusp. This happened during northward IMF and high solar wind
densities. The best FUV data were recorded after perigee
with close distance to the Earth and were obtained on
2000-262-01:30-06:00, 2000-279-06:40-09:00 and
2000-311-22:00-23:00.
|
FUV stellar calibration, Gladstone |
Initial results of calibration of the FUV instrument
against known stellar objects will be presented and
compared with pre-flight and dayglow modeling results.

Abstract |
Survey of plasmasphere properties and forward modeling, Sandel |
Current efforts to survey the total He+ plasmasphere
content will be discussed, along with a survey of
the position, shapce, and motion of the plasmapause.
Forward modeling of the plasmasphere will also be discussed.
|
MSM simulations of May 24, 2000 and comparison to EUV data, Goldstein |
MSM modeling is done for the May 24, 2000 event, to attempt
to reproduce key features (stripped-down plasmasphere,
afternoon sector drainage tail, morning sector "shoulder")
of the plasmaspheric configuration inferred from EUV images.
Successful modeling of global plasmaspheric configuration
(which we see for the first time via EUV data), and the
inverse problem (deducing electric fields from EUV images)
may be of interest for an extended mission proposal. Solar
wind and IMF data are available from ACE, Wind, IMP-8, and
Geotail.
|
Steep density gradients observed by RPI, and comparison to sharp edges in EUV images, Goldstein |
Toward the goal of calibrating the EUV images, an attempt is
made to correlate the locations of steep density gradients
(as observed in situ by RPI) with EUV "Helium edges;" i.e.,
sudden drops in brightness in the remotely-sensed Helium
emissions of EUV images. The study incorporates 450 RPI
density measurements from approximately 140 passes (June-
August,2000) of IMAGE through the plasmasphere.
|
Future LENA study directions, Moore |
Future LENA study directions: solar wind LENA variations and
long term trends; substorm and storm variations in LENA
environment; perigee pass outflows and relationship to
auroral activity and to solar wind variations.
|
Proton precipitation in substorms, Mende |
This work is supposed to be a multi event study intended to
study systematics of the proton signatures of substorms for
JGR. We have not identified the events yet.
