Penumbral Moving Magnetic Features




Draft


Most recent draft is here.


Paper Rewrite -- Remaining Tasks

  1. Magnetogram MMFs: better statistics - SWAMIS code
  2. Application to models - flux emergence?
  3. Trace inclination variations as functions of radius, time
  4. Decay of sunspot: what is flux removal rate?
