DESCRIPTION:Speakers: Anthony Yeates (Durham University)\nQuasi-static mod
 elling of the Sun’s corona using the magneto-frictional approximation ma
 kes predictions of how its large-scale magnetic structure might vary over 
 the solar cycle. Unlike the traditional potential field source surface mod
 el\, this approach is able to probe the effects of low coronal electric cu
 rrents and the corresponding free magnetic energy. In particular\, ongoing
  footpoint shearing and flux cancellation lead to the concentration of fre
 e energy within closed-field regions\, naturally forming sheared arcades a
 nd magnetic flux ropes. I will show model results for Cycle 24 driven by m
 agnetogram data from SDO/HMI\, with the aim of comparing to earlier result
 s from a decade ago for Cycle 23. In particular\, we will consider how sol
 ar flux ropes and their eruptions vary over the solar cycle\, at least acc
 ording to this model.\n\nhttps://meetings.aip.de/event/24/contributions/35
