I think that Voyagers are the coolest mission.

Seconded.

I think this combined plot speaks by itself:

V1 is definitively inside a totally new region...

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.

Thanks for the link, TheAnt!
This recall me to update the plot:

After two more weeks, initial impression became a robust trend!

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

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.

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!

News release: NASA Voyager 1 Encounters New Region in Deep Space.
QUOTE
December 03, 2012

PASADENA, Calif. -- NASA's Voyager 1 spacecraft has entered a new region at the far reaches of our solar system that scientists feel is the final area the spacecraft has to cross before reaching interstellar space.
