This is what I've advertised here some months ago. :)
We're currently experiencing a lull in activity. I still hope in the coming months we'll restart the thing and add more features, but some of the key people (myself included) are busy doing other stuff, unfortunately.

Eugene,
It would help if key people worked together here. Robertus Maximus and Solar have key pieces of information for scales that David, Chris, etc, can help map in Plasmascape. Also, Gareth of “See the Pattern” on YouTube, can make this material more readily accessible to the newbie, as he has with a number of EU and other “non-mainstream approved” topics.
If you want, consider Robertus probably the expert on Plasmascape scales from Sun for sure, up to heliosphere, possibly. Solar should be the “go to” for local interstellar cloud scale, for sure.
My dream, would be maybe you and Gareth, interview these two first. Possibly include DJ if he isn’t overcommitted with other tasks.

My general point, is that with these still too splintered groups of the Thunderbolts forum, “See the Pattern” YouTube site, “Plasmascape”, “The Electric View” Skype group (also on YouTube, sometimes), etc, too much information is falling through the cracks, or at least, not channeled to those who need it. i.e., the geeky details we need in Plasmascape, vs the general speculation that is also encouraged in “the Electric View” discussions.

I'd like a decent in-detail talk on skype, but neither of them uses it, as I understand.
Gareth is on Plasmascape chat already. Though not much is happening there recently.
And yes, I agree that a lot of useful info is falling through the cracks. Organizing research is not an easy task.
Recently I became concerned with another - related - problem: that a lot of not useful info does not fall through the cracks. And some people keep clinging to their theories despite the evidence that they don't work (e.g. the anode Sun model).

Voyager 2 at the Edge

Charged particle measurements

A recent series of scientific papers revealed Voyager 2’s findings at the edge of the heliosphere.

“Voyager 1 (V1) exited the heliosphere on 25 August 2012 at a distance of 121.6 AU (18.3x109km) and latitude 34.5 degrees (using the heliographic inertial coordinate system) and within a few degrees of the nose of the heliosphere… Voyager 2 (V2), on a slower trajectory than V1 and south of the heliographic equatorial plane at a heliographic latitude of around -32.2 degrees… (o)n 5 November 2018, V2 crossed the heliopause (HP) at a distance of 119AU (17.9x109km) at 218 degrees heliographic longitude.” (1)

With both Voyager spacecraft now in the local interstellar medium (LISM) a reasonable assessment can be made of their findings and how it fits, or perhaps does not fit, with the proposal on this thread.

“The heliosheath (HS) is also the principal acceleration region for anomalous cosmic rays (ACRs) most of which were previously thought to be accelerated at the termination shock (TS). V1 encountered a plasma stagnation region 8AU before crossing the HP, when the radial component of the solar wind became zero and later became intermittently negative, while the tangential flow was nearly steady at around 40km/s in the –T direction (in conventional RTN (radial-tangential-normal) heliographic coordinates, in which the +T direction is that of planetary motion around the Sun).” (2)

Voyager 1 exited the heliosphere during solar maximum conditions (mainstream researchers tend to factor in a solar cycle ‘delay’ when interpreting the data from both Voyager spacecraft) when it detected a counter-rotating solar wind flow, how does this compare to Voyager 2’s findings?

“The intensity fluctuations in the electrons are much more pronounced than those of ions of similar energies, indicative of substantial plasma/magnetic field structures sensed by the small gyroradius and relativistic speeds of the electrons.” (3)

Voyager 2 found that ‘structures’ were heavily influencing electrons and ions at the HP.

“Thus, heliospheric material is apparently leaking out of the HS to >0.6AU beyond the HP…”. “…at V2, there are both low and high energy ions upstream of the HP, and they persist to at least 0.6AU, while ACR protons are apparently present to >1.1AU. Not surprisingly, they flow along the interstellar magnetic field away from the HP…” (4)

In the 1970’s Ralph Juergens suggested that cosmic rays were the ‘return current’ of stars with a greater potential than the Sun; the potential of our own Sun causes ‘material’ to ‘leak’ out of the heliosphere. Juergens theorised that solar wind protons (i.e. ‘return current’) were the main current carriers powering the solar discharge, Voyager 2 has found the ‘return current’.

“…ions of >3MeV inside the HP are nearly isotropic, although at E>28keV, they show motion away from the nose of the heliosphere (+T direction). Those outside the HP, however, move primarily in the –T direction along the magnetic field…” (5)

Voyager 2 exited the heliosphere under solar minimum conditions at the spacecraft’s latitude it found charged particle motions opposite to those found by Voyager 1, outside of the heliosphere the motions reversed again- counter-rotating you may say.

“The tangential component fluctuated between 60km/s and 160km/s in the +T direction… with occasional excursions of >50km/s, and substantial structure, particularly close to the HP. The radial component ranged from a few kilometres per second to 100km/s, but was occasionally close to zero, such as on 2017.3, and again on 2018.4 at distances of 114AU and 117AU, respectively. Further there are remarkable excursions in the tangential component in late 2017 and 2018, suggestive of deep penetration of the Galactic magnetic field through the HP…” (6)

Voyager 2 not only found the tangential solar wind flow to be opposite to that measured by Voyager 1, but large variances were suggestive of ‘Galactic’ structures influencing the heliosphere itself.

“At V1…there were multiple episodes of magnetic flux tubes containing enhanced field and GCR intensities.”

“…It is clear that no radial inflow was seen on the upwind flank of the HP. (by V2) The contrast with the interaction at V1 is obvious. There is inflow of cold Galactic plasma in this case. The observed angular distributions reflect this inflow and suggest a field line interchange, all consistent with a flux interchange instability at the HP boundary.” (7)

As has been suggested on this thread, at solar maximum, current arriving at the Sun is not focussed near the Sun’s polar regions rather it becomes more filamentary arriving at lower latitudes- this is what Voyager 1 found by contrast and although there were many similarities, Voyager 2 found a more orderly HP as would be expected during solar minimum conditions.

On the ‘tangential’ solar wind component

Mainstream solar scientists view both Voyager spacecraft as exiting the heliosphere in the ‘nose’ direction, I disagree. I have made the case in earlier posts that the concept of ‘nose’ and ‘tail’ are incorrect. To my mind both Voyagers have left the heliosphere in a pinched region of the ‘heliotube’ and as such the tangential solar wind may be interpreted as a ‘wrap-around’ flow along the long axis of the ‘heliotube’.

Voyager 2 at the Edge

Magnetic Fields

“…the Voyager 1 spacecraft, moving radially in the northern hemisphere, which crossed the heliopause on 25 August 2012 at a distance of 121.6AU. We show using observations of the magnetic field and energetic particles that Voyager 2 crossed the heliopause in the southern hemisphere on 5 November 2018 at a distance of 119.0AU. Voyager 2 observed a much thinner and simpler heliopause than Voyager 1 as well as stronger interstellar magnetic fields, and it discovered a ‘magnetic barrier’ in the heliosheath that strongly influences the entry of cosmic rays into the heliosphere…These observations, together with the Voyager 1 observations and existing models, show that the magnetic barrier, the heliopause and the neighbouring very local interstellar medium form a complex interconnected dynamical system.” (1)

At solar minimum, Voyager 2 found a far simpler, less chaotic heliopause than Voyager 1 found at solar maximum, this time, however, the LISM magnetic fields were stronger than those measured by Voyager 1.

“It is conventional to measure magnetic field direction in a spacecraft-centred radial-tangential-normal (RTN) coordinate system. In the RTN coordinate system, R is the unit radius vector directed radially from the Sun, T is the cross-product of the solar rotation vector with R, and the unit vector N completes a right-handed system…the azimuthal angle was close to 270 degrees throughout the interval…Thus, the average azimuthal angle before the heliopause crossing was the same as the average angle azimuthal angle after the heliopause crossing…The largest component of B was the BT component, which was negative (directed opposite to the direction of solar rotation).” (2)

Once again we see a ‘tangential’ magnetic field were the radial magnetic field is highly diminished; as previously mentioned the ‘tangential’ nature of the magnetic field applies only to mainstream models of the heliosphere. The expected sharp difference between solar and interstellar magnetic fields has not been found rather there has been a gradual change as if the heliopause is a structure surrounded by a much larger structure in the LISM.

“…the magnetic barrier, the (particle) density was relatively high (reaching a maximum 0.004 cm3), the temperature was high (60,000K) and the speed was relatively low (but still 100 km/s)… shows the magnetic barrier as a porous barrier to the >70MeV nucleon cosmic rays…thus the magnetic barrier, with its strong magnetic fields in the heliosheath, acted as a ‘leaky barrier’ to the cosmic rays from the VLISM.” (3)

A region of higher magnetic field strength coincides with a drop of cosmic rays approaching the heliosphere, is the ‘magnetic wall’ or ‘magnetic barrier’- an indication of the Sun’s potential?

“Voyager 2 crossed the heliosphere from the magnetic barrier and entered the VLISM on 5 November 2018 (day 309) at a distance of 119AU from the Sun. The magnetic field strength increased to 0.68 nT across the heliopause and the counting rate of the >0.5 MeV nucleon particles decreased across the heliopause, as observed by Voyager 1 when it crossed the heliopause in 2012. The heliopause observed by Voyager 2 was stable and thin, in contrast to the unstable thick heliopause observed by Voyager 1… Observations from Voyager 1 have shown that shock waves and pressure waves can propagate through the heliopause and into the VLISM…The magnetic field strength observed by Voyager 2 in the VLISM (0.68+/-0.03 nT) was significantly larger than the draped magnetic field (0.49 nT) of the VLISM observed by Voyager 1, indicating an asymmetry of the heliosheath and heliopause…As observed by Voyager 2 , there was either no net change or a very small change in the magnetic field direction from one side of the heliopause to the other.” (4)

The Voyager spacecraft found a similar but different heliopause, the main asymmetry is related to the solar cycle and not to the location of the two spacecraft. The VLISM now shows a stronger magnetic field and appears more ordered. During solar maximum the heliopause and VLISM was more chaotic with the appearance of ‘flux tubes’.
With increasing distance from the heliosphere Voyager 1 has found that charged particle levels gradually increase, if both Voyager spacecraft are still functioning by the maximum of Solar Cycle 25, estimated to occur between 2023 and 2026, I predict that both spacecraft will find traces of the solar cycle beyond the heliosphere- as it is beyond the heliosphere where the solar cycle originates.
