Title, Author Abstract
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.

Title, Author 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.
