This is a " bolt on blog " to my earlier Jan 15 2009 blog, on Spiral Sunspots The bolt on, is prompted by my locating an early NOAO (National Optical Astronomy Observatory ) picture imaging a rare Spiral Sunspot. ( noao.edu Image Gallery / Sun. ). when the images will appear when clicked }. This is quite an old image , and was taken by the Kitt Peak Vacuum telescope in 1982. The absence of explanations as to its origin, is indicative of an " entrenched " solar / sunspot anomaly barrier.
This example is a, " Surfacing Spiral Sunspot." ( Strangely, this Sunspot has a fleeting resemblance to a Sea Horse ) . Sub-Surface Sunspots however, will ocurr much more frequently within the Suns Interior, remaining invisible to us , and disintegrating out of sight, as they are subjected to impacts from massive infalling debris, resulting from the disintegrating spiral jet contrails. Unless as the specimen discussed, they appear on or nearing the Suns photosphere. Subsurface Spiral Sunspots , will, it is anticipated disintegrate more rapidly, due to impacts from infalling jetted residue. The Solar Core, and its jets, have, of course long lost their ability to jet at escape velocity, and can only jet to sub orbital velocity.
The Surfacing Spiral Sunspot imaged, at noao.edu posesses distinctive architecture that provides clues that indicate that the Spiral Sunspot is indeed Jetting and Precessing. It can be clearly observed that the wide jet contrail is sweeping out a spiral path as the Sunspot Core Jets are carried around as dictated by the sunspot cores angular momentum. The core of course has twin jets, and the inner jets, also precessing , are projecting into the Suns interior, and remain invisible to us as observers.
