I think you'll find the clue was in the graphic you posted; ionisation of cometary neutrals by solar UV. Ions then interact with known and measured solar wind and IMF.
Nothing there about non-existent electric woo on the comet, or unexpected, non-observed currents from the Sun.
As usual, plenty of (bad) interpretations, and still zero evidence.
Whilst were on the evidence thing me 'ol mate can you tell Stefano Mottola PI for ROLIS that the comet MUST HAVE DUST!
surprised to find no fine dust...ok where do you think the fine dust is located Jonedave116? Should be good for a giggle
Because he say's at 0:40 we see NO dust!
We see gravel/pebbles and we'll have to work out were these came from!
Mmmmm.... from the rock that is 67P!
Looks, again like your dirty snowball is in serious trouble most probably fatal only to be saved with ad hoc and bizarre explanation that until you have dig sound plausible
So, no DUST or ICE on the surface! so of course invoke your magical pink unicorns and hide it under the poorly thermally conducting very porous surface, that has cracks and fractures (but no sublimation strangely), never to be tested by Philea!
brilliant dodge and weave there sport!

THEMIS mission
Was that an apology for Kristian Birkeland, I heard? Dude nailed it 1908

So where are these currents around the comet? Have a look at the magnetic data preceding, during and following the jet observed on 29 July. <70nT down to ~2nT. No electric currents in that cavity. None in the cavity at Halley. No solar wind, and only cometary ions detected. Where are they coming from? Not the solar wind and nothing electrical. Sunlight still gets through, though.
Hilarious watching you back peddle!
Nearly as funny as watching
To the non existent "ice" and "dust"?????
What the hell are you on about now? They've seen dust. They've seen what is almost certainly ice. They've detected water vapour and CO2 and various other gases. They excavated H2O from Tempel 1.
So no, there is plenty of evidence for ice and dust. Including the density, which isn't that of rock, by the way.
What we see no evidence of is electric woo, or enormous increases in the solar wind flux to create the observed gases.
As I keep saying, you have zero evidence for this crankery.
Again, what the hell are you on about? There is zero evidence for the electric sun woo. But this is not the thread for that. This is about comets and the total lack of evidence for any electric woo thereon.
