NLFFF extrapolation of an emerging active region
9 September 2011
A new EIS nugget for the month of September has been written by G. Valori of LESIA-Observatoire de Paris. Nonlinear force-free field (NLFFF) extrapolation was used to investigate the structure of the field at the time of the main emergence. Here, the extrapolation is based on an SOT/SP vector magnetogram obtained from the scan on 4 July 11:58-12:34 UT. You can read the full text here.
