New Information on the Interstellar Magnetic Field in the Solar Neighbourhood
This thread originally began as a rejoinder to Bob Johnson’s EU2013 presentation in which the validity of the Electric Sun model was questioned. (1)

I had offered a possible route out of the criticisms raised by Bob Johnson by combining Hannes Alfven’s ‘closed circuit’ with Ralph Juergens’ ‘open circuit’ solar models. The result is what I have called a pseudo-Alfven circuit which is ‘open’ i.e. connected to the Sun’s environment, performing the role proposed by Juergens.
Later, I questioned the ‘accepted’ view of the heliosphere suggesting that the Sun, resides in a ‘Heliotube’.

From the two images in a previous post (
https://www.thunderbolts.info/forum/php ... 25#p127597) it can be seen that the IBEX Ribbon spans the pinched region of the Heliotube covering both northern and southern solar hemispheres. Now, a new study has shed additional light upon the Sun’s environment. (2)
The collected data “… show filament-like patterns of polarization position angles, which are related to both the heliosphere geometry, the kinematics of nearby clouds, and the Interstellar Boundary EXplorer ribbon magnetic field.” (3)
Despite the Interstellar Magnetic Field (ISMF) direction varying “strongly in different parts of the sky” coherent features nevertheless appeared: “The general view may be slightly complicated, but there are several interesting features showing well-aligned polarization vectors. Some of them resemble “arc” or “loop”-like structures.” (4)
“The polarization position angle patterns suggest that the polarizing dust grains are aligned along magnetic filaments, some with spatial extents greater than 90 degrees. Combined with data from several literature sources, Frisch et al. (2015a) found that the position angles for stars in the longitude range l = 315 degrees – 60 degrees reveal a filament in the direction toward the heliosphere nose region, as defined by the flow of interstellar neutral gas through the heliosphere (l - approx. 4 degrees, b - approx. 15 degrees). Our data also clearly show a filament in the opposite direction (l – approx. 180 degrees, b – approx. -15 degrees) corresponding to the (spatially broader) region of the heliosphere tail.” (5)
“The newly discovered filament that is centered near l = 240 degrees, b = -42 degrees roughly follows the direction of the IBEX ribbon ISMF.” (6)
We find a new filament in the ‘tail’ region of the heliosphere to compliment the known filament in the ‘nose’ region of the heliosphere. It can be seen from my illustrations that the discovery of a filament in this region should not have come as a surprise.
“These new polarization data firmly place the filament within the cluster of local interstellar clouds flowing past the Sun and extending to the solar location (Frisch et al. 2011).” (7)
“…a polarization map for the nearby stars at northern Galactic latitudes, for comparison with earlier results for more distant stars (Berdyugin et al. 2014). The most prominent feature seen in the northern (b > 30 degrees) high-latitude polarization map for the distant (d >= 100 pc) stars is a giant “arc” or “loop” between the longitudes 270 degrees and 45 degrees, with the center at l = 330 degrees.” (8)
“The polarization position angles show that the very local ISMF is arranged into distinct magnetic filaments, some with spatial extents greater than 90 degrees. These magnetic filaments provide a new perspective on the structure of local interstellar clouds…” (9)
“Comparison of polarization maps at the high northern Galactic latitudes for distant (100 pc < d < 500 pc) and nearby stars (d < 50 pc) reveals similar features of polarization patterns, that is, local magnetic field structures seen in the distance range d = 100–500 pc also extend to and appear at closer distances.” (10)
It would appear that we have a continuum of observations hinting that filaments in the Local Interstellar Medium (LISM) are directly influencing the heliospheric boundary. It must be kept in mind that I do not accept the consensus view of the heliosphere (I am using the term here for convenience) along with the consensus interpretation of the ‘nose’ and ‘tail’ regions. The discovery of a filament in the ‘tail’ region, I consider to be further evidence that the consensus view is wrong. I would also offer the possibility that the reported circularity of the IBEX Ribbon may be an illusion due to our observational perspective. Instead, the IBEX Ribbon may be related to filaments snaking along the ‘Heliotube’- further observations may confirm or deny this possibility.
