Type: Oral Session: SH 3.5,SH 5.1, SH 5.2
Track: SH.5.2
Since 1996, energetic hydrogen and helium atoms (ENAs) have been identified and their fluxes are monitored by the High-Energy Suprathermal Time-of-Flight sensor (HSTOF) of the Charge, Element, and Isotope Analysis System (CELIAS) on the Solar and Heliospheric Observatory (SOHO) near the Lagrangian point L1. ENAs, neutralized via charge transfer reactions, move along ballistic trajectories una ... More

The energy spectra of protons in the 1-100 MeV range are studied under quiet solar activity periods during the 21st - 23rd cycles using data sets from near- Earth spacecraft. A series of low-flux spectra is approximated by the form J(E) =AE(^-g)+CE^n, the two terms describing solar/heliospheric and galactic components, respectively. By determining the best fitting parameters to the energy ... More

Track: SH.5.1
We examine the Voyager 1 (V1) and Voyager 2 (V2) intensity vs. time profiles in several energy bands of low-energy particle populations during the period 2005 through early 2007. There appear to be a set of propagating structures with ~1 year duration that appear first at V2, which is upwind of the solar wind termination shock, and then ~115 days later at V1 in the heliosheath. We will d ... More

Track: SH.5.1
Since the December 2004 termination shock transit of Voyager 1, Voyager 2 data have shown partly analogous, partly dissimilar features to the pre-shock activity seen by Voyager 1. One important point is the different energy dependence of suprathermal and mildly energetic omnidirectional particle flux variations for the two data sets. First harmonic anisotropy amplitudes and phases also displa ... More

IBEX-lo on the Interstellar Boundary Explorer (IBEX) will image energetic neutral H atoms (ENA) from the termination shock at 10 – 2000 eV and the flow distribution of interstellar O in spring and fall. The sensor combines a mechanical collimator to restrict the detectable arrival directions, an atom to negative ion conversion surface, an electrostatic analyzer, post-acceleration up to 20 ... More

The Virtual Cosmic Ray Observatory (ViCRO) is proposed to extend planned capabilities of NASA’s existing or developing heliophysics virtual observatories with a collection of important cosmic ray datasets with an initial focus on interplanetary solar and heliospheric science applications. Recent work from the Advanced Composition Explorer (ACE) and Voyager spacecraft shows the science value ... More

Track: SH.5.1
Voyager 1 (V1) continues to explore the heliosheath after crossing the solar wind termination shock on 16 December 2004. Voyager 2 (V2) is observing termination shock particles (TSPs) and may cross the shock at any time. The source of the classic anomalous cosmic rays (ACRs) is still under debate as it was not located at the shock where V1 crossed (~34 N heliolatitude). The ACR spectrum at ... More
