Monitoring the velocity of the interplanetary hydrogen
Abstract
We are proposing to use HST/STIS over a single orbit to make Lyman-alpha observations of the interplanetary hydrogen {IPH} during the March-April period of this year {2013}. This special request is driven by the need to resolve the current controvery between Ulysses and IBEX results, to better characterize the trend of the IPH velocity with the solar cycle, and to provide new constraints on the state of the local interstellar medium. Monitoring the IPH velocity is a keystone to understand the dynamics of the heliosphere and the local interstellar medium. Results can be applied to the study of astrospheres.
