Voyager CRS Summary Plots

Voyager 2 CRS 0.5 MeV plot
Voyager 2 CR >70 MeV plot
Voyager 1 CRS 0.5 MeV plot
Voyager 1 CR >70 MeV plot

These plots above from the Voyager 1 and 2 Cosmic Ray Experiments (CRS) show the most recent six-hour count rate data from low and high energy proton channels as these spacecraft move outward within and beyond the heliosheath. This is the barrier region of high local fluxes between the supersonic heliosphere and local interstellar space. Full mission plots from these channels are shown below. The CRS Principal Investigator is Professor Edward C. Stone of the California Institute of Technology. On behalf of the CRS team, Dr. Nand Lal of the NASA Goddard Space Flight Center maintains the CRS data site for public access
here.

Mission summary plots of six-hour average counting rates for > 0.5 MeV and > 70 MeV protons from the Cosmic Ray Subsystem (CRS) experiments on Voyager 1 and 2. The two plots are updated yearly. The proton data are taken directly from the CRS team website here. Solar distances in AU for each spacecraft are also shown.
