WE OBSERVED THAT
- Both sunspots were surrounded by intense, nearly radial
moat flows (diameter about 70").
- MMFS originated at the penumbral boundary and
migrate outside through the moat.
- Most of the MMFs appeared in closely
spaced pairs of opposite-polarity magnetic elements.
- Usually, the
magnetic element of sunspot polarity came out first and only then, the
second magnetic element of the opposite polarity appeared on the scene.
- Frequently magnetic elements in a pair were not equally visible:
opposite (to the sunspot) polarity element was often observed as a
loose and weak magnetic structure.
