The Advective Flux Transport Model: Improving the Far-Side with Active Regions observed by STEREO 304Å

Lisa A. Upton, Ignacio Ugarte-Urra, Harry P. Warren +1

Observations the Sun's photospheric magnetic field are often confined to the Sun-Earth line. Surface flux transport (SFT) models, such as the Advective Flux Transport (AFT) model,…

Assessing the Performance of the ADAPT and AFT Flux Transport Models Using In-Situ Measurements From Multiple Satellites

Kalman J. Knizhnik, Micah J. Weberg, Elena Provornikova +7

The launches of Parker Solar Probe (Parker) and Solar Orbiter (SolO) are enabling a new era of solar wind studies that track the solar wind from its origin at the photosphere, thro…

Solar Cycle Observations

Aimee Norton, Rachel Howe, Lisa Upton +1

We describe the defining observations of the solar cycle that provide constraints for the dynamo processes operating within the Sun. Specifically, we report on the following topics…

Solar Cycle Precursors and the Outlook for Cycle 25

Lisa A. Upton, David H. Hathaway

Sunspot Cycle 25 over 3 years past the cycle minimum of December 2019. At this point, curve-fitting becomes reliable and consistently indicates a maximum sunspot number of 135+/-10…

Physical Models for Solar Cycle Predictions

Prantika Bhowmik, Jie Jiang, Lisa Upton +2

The dynamic activity of stars such as the Sun influences (exo)planetary space environments through modulation of stellar radiation, plasma wind, particle and magnetic fluxes. Energ…
