Magnetic Flux Emergence and Decay Rates for Preceder and Follower Sunspots Observed with HMI
A. A. Norton, E. H. Jones, M. G. Linton +1
We quantify the emergence and decay rates of preceder (p) and follower (f) sunspots within ten active regions from 2010-2014 using Space-weather Helioseismic Magnetic Imager Active…

Tilt Angle and Footpoint Separation of Small and Large Bipolar Sunspot Regions Observed with HMI
Bruce H. McClintock, Aimee A. Norton
We investigate bipolar sunspot regions and how tilt angle and footpoint separation vary during emergence and decay. The Helioseismic and Magnetic Imager on board the Solar Dynamic…
