Example of the highest flux active region from the Helioseismic Emerging Active Region Survey (Schunker et al. 2016). The line-of-sight magnetic field is shown at three times during the emergence process. The emergence time, t = 0, is defined as when 10% of the maximum (over the 36 hours after the active region was given a NOAA number) magnetic flux has emerged. The red curve outlines the area A we used for the analysis of this active region emergence.
