    Sunspots 3112, 3116,3119,3120 and 3118
  9. It's a question, rather several questions that may seem strange currently by referring to your sites Space weather live and space weather.com we see that there are 7 sunspots, the earth is moving towards sunspots 3075 and 3076 (correct me if I'm wrong) But in this case if what I don't understand is how can sunspots 3068, 3072 and 3073 still send us solar winds? And also when will we be safe from them? I don't know how it works but I imagined the earth would be out of their line of sight
  10. Howdy All Y’all, There have been a number of interesting posts under other topics regarding Jupiter’s influence - and that of the barycenter of the solar system, particularly when Jupiter is in Sagittarius, pulling the barycenter toward the center of the galaxy. After a little research and following the conversations across various topics, I thought I would create topic just for this stuff… Here is an excerpt from a post a few,days ago which I found particularly interesting: (I can’t seem to quote a post from another topic in here) Archmonoth wrote: (excerpts from Jun 6) So here is my hot take on mass/gravity influence: Distances, Weights, and Speculation: Galactic Core= 4 million solar (Sun) masses. Distance from the Sun: 8,000 parsecs, each parsec is 3.26 light years, each light year is 9.46 trillion kilometers, and 8 parsecs is 246,716.8 trillion kilometers. This means the pull of the core is 4 million masses divided over 246,716.8 trillion kilometers, and via the Inverse Square law, would mean, whenever the distance doubles, the gravitational pull is decreased by a factor of 4. This continues for 40 steps (1/2 distance) until you reach a distance of 897,000 kilometers (edge of Sun’s radius is about 700k) with a pull of 0.000,000,000,000,005,05 solar masses. (1.01x10^16 kilograms) I’m not saying the gravitational pull is 1.01x10^16 kilograms but is the equivalent gravitational pull of that weight at a distance of 897,000 kilometers. Jupiter is 778,000,000 kilometers from the Sun and has a weight of about 1/1047th (.00095) solar mass. Jupiter’s pull on the Sun at 759,765 kilometers (near the Sun’s edge) is 0.000,000,000,898 solar masses. This is many magnitudes above the gravitational pull of the galactic core. (1.796×10^21 kilograms) So, Jupiter increases the pull towards the center of the galaxy when in alignment and inversely changes when on the other side of the Sun. This tells me there is an acceleration and deceleration of the Sun’s velocity as it travels around the barycenter at different times during Jupiter’s orbit. Earth’s mass/distance: Mass: 1/330,000 Solar masses. Distance from the Sun: 149,000,000 kilometers Which is to say the Earth’s pull on the Sun at 582,031 kilometers (Just inside the Sun’s Radius) is 0.000,000,000,453 solar masses. (9.06×10^20 kilograms) Earth has about half the influence as Jupiter has on the Sun. The ratio and the amount are not overly important, just trying to express that there is an additive pull towards the galactic core. Each planet in alignment would add more acceleration and equivalent conservation. So, because of the acceleration, there is a curve/turn occurs in the barycenter and momentum is conserved. My guess is that this conservation duration takes 1 solar cycle (11ish years) to complete, returning to the solar minimum after the sunspots approach the equator (butterfly pattern). This is correlative with Jupiter aligning with Sagittarius (galactic core) and Jupiter’s orbit being 11.82 years. JUPITER IN SAGITTARIUS DATES December 25, 1982 - January 19, 1984 December 9, 1994 - January 3, 1996 November 23, 2006 - December 18, 2007 November 8, 2018 - December 2, 2019 October 22, 2030 - November 15, 2031 Here are the start times of solar cycles: Solar cycle 22: 1986-09 Solar cycle 23: 1996-08 Solar cycle 24: 2008-12 Solar cycle 25: 2019-12 My assumption/guess is that sunspots, flares, and CMEs are partially the result of energy/momentum being conserved after Jupiter (and other planets) changes the Sun’s velocity. End excerpts… I also found an interesting diagram showing the location of the barycenter relative to the sun… Note, a more accurate depiction would be to have the barycenter stationary and the sun orbiting it. Also, this orbit around hi the barycenter is a chaotic non-linear dynamic system. It has no closed form solution, so everything going forward should be taken with a big hunk of salt, due to “sensitivity to initial conditions”. Also note, the path of the sun around the barycenter is confined to what we would call a “strange attractor”. Never repeating, but confined to a bound region. if y’all don’t mind - please repost your posts on this topic here - at least the interesting ones… Sorryit too, so long to get this started! WW
