I think this combined plot speaks by itself:
V1 is definitively inside a totally new region... Source: http://voyager.gsfc.nasa.gov/heliopause/he...recenthist.html -------------------- I always think before posting! - Marco -

It really looks like it.
That particle/proton rate have stayed low for 2 more weeks, whereas the galactic cosmic rays continue to climb slowly. And turning of the spacecraft to look for any possible sideway movement did show that the particles were not moving sideways either. (Also described in the summary linked by Paolo.) Isn't that exactly the conditions to expect at the boundary of the heliopause? Now data from IBEX suggest there might be no bow shock zone at all. So all will depend on how deep this area might be, after that Voyager 1 might very well be in true Interstellar space. Related story 'The little motor that could' |

Thanks for the link, TheAnt!
This recall me to update the plot: After two more weeks, initial impression became a robust trend! -------------------- I always think before posting! - Marco -

NASA will host a media teleconference at 11 a.m. PST (2 p.m. EST) on Monday, Dec. 3, to discuss the latest findings and travels of NASA's Voyager 1 spacecraft. MORE HERE

Dilo
Are your graph labels are correct >70 and >0.5 not >70 and <0.5?? -------------------- |

That's what the original graphs say.

What am I missing. >70 is also >0.5, so how can >70 be going up the last month and >0.5 be going down????? Never mind--two different detectors measuring different types of particles, not one detector measuring two energy ranges.

However - the value of >70 is small compared to >0.5
It's risen from only 2 to 2.3 Whereas the >0.5 has dropped from 25 to about 2.3 i.e. - the amount of particles between 0.5 and 70 has dropped to essentially zero. |

Dilo Are your graph labels are correct >70 and >0.5 not >70 and <0.5?? Labels were correct (copied from original) but their postions on vertical axes were wrong! This is the correct (and updated) 1-year trend: Sorry for mistake! -------------------- I always think before posting! - Marco -

So much for there being a clear cutoff point
