摘要: Ideas and models for the appearance of photospheric magnetic structure are confronted with observational data. Some findings are: The flux emerging in an active region consists a bundle tubes which were already concentrated before penetrating into photosphere. A model rising bunch joining few strands at larger depths describes coalescence spots near leading following edges while more may surface center region. There is no evidence appreciable helical twists bundles.
