cenzi, the link below may answer your question. I hope it does. We are moving roughly 60ish degrees to the left of the Galactic Centers direction and a bit left of Altair.

A Plumb-bob placed under an overhang or similar shadow casting structure will give you Astronomical Noon, as the ancients knew it. You actually don't even need a plumb-bob as you become familiar with the object's shadow progression each day. A sundial is the perfect time keeper as well. I've...
Integral,
It varies alot. I used 'high noon' in my earlier comments, which is a common term. But the time I use is Astronomical Noon. The beauty of this moment is the shadow cast confirms the moment, using angles of the shadow pre-noon and post-noon helps visually see the time approach and...
Jim, thanks for your interest in my interest.
I live near Houston, TX. My home faces as near to True North as possible. My roofline casts a shadow across my front yard at 'high noon' that is clearly observable. I have marked this shadow line (100 feet from east to west) at both the Winter...
I have watched the Sun's shadow make its trek from the solstice moments for many years. I have it marked and like to observe it as Earth's tilt reaches it's maximum point, from Summer to Winter and back. I used a heliodon to built a large structure (80 feet long/12 feet tall=roofline of my...
Good question Simon. The density flucuates according to 1) He availability around the outside of the Heliosphere (flucuates); 2) The strength of the solar wind (fluctuates); 3) Speed of the Heliosphere's travel through space (flucuates). We don't have historical density data for this zone, so...
Steve,
The following links are as much detail as is available, I suppose. Not sure they can answer your questions. Might try emailing some of the POCs on the last report. Good luck.

Thanks for your reply Simon. I know my question seems to answer itself, but with regards to electromagnetics of larger fields and objects, I am trying to oversimplify the obvious because of the scientific efforts in understanding space weather theory and electromagnetic predictions. So you...
Given the above quote reference Helium within our Heliosphere, I have a grouping of questions for the electromagnetic wise.
If Earth and Jupiter were both placed within a dense Helium plasma region/field of our Heliosphere at the same time; and considering He plasma's high electrical...
