AB: The Pioneer 10 (P10) Lyman Alpha dataset is the only dataset that is available for the study of the very local interstellar medium (VLISM) in the downstream direction relative to the incoming interstellar neutral hydrogen flow, at very large distances from the sun. Selected P10 data obtained in 1984 and 1986 at distances between 31.81 to 32.25 and 37.29 to 37.74 AU have been used to estimate the local interstellar neutral hydrogen and proton densities. State of the art, stationary neutral-plasma and radiative transfer models have been used in the interpretation of the data. No VLISM heliospheric model was found that best fitted both the P10 1984 data and the 1986 data. The most probable cause for the failure to find a single best fit model is neutral hydrogen density fluctuation due to heliospheric time-dependence. The result obtained here is in qualitative agreement with recent Voyager 1 observations.
