VOYAGER RECENT 6-HOUR HISTORY

The Cosmic Ray Subsystem team has made available plots and listings of 6-hour averages of two counting rates, PGH and LA1. The PGH rate consists of greater than 70 MeV/nuc nuclei, primarily protons, and is a good indicator of the level of modulation of galactic cosmic rays. It can also respond to large solar flares. The LA1 rate consists of greater than 0.5 MeV/nuc nuclei, principally protons, and is sensitive to low-energy phenomena in interplanetary space (e.g., co-rotating interaction regions, associated enhancements and solar flares).

The most recent 6-hour averaged figures for the LA1 and IPGH Rates can be displayed by selecting the thumbnail images below.

These figures are updated several time each week as new data becomes available.
