Day 1 (Tuesday, August 2), Day “theme” – Synoptic data

9:00am opening remarks, ISSI introduction by Mark Sargent.

  1. Introduction and updates on synoptic data/pseudo-magnetograms – Alexei Pevtsov
  2. “Chromospheric Solar Activity Over Multiple Decades” – Luca Bertello
  3. “AIA 1600 Å contrast as a proxy of solar magnetic fields” – Ismo Tähtinen
  4. Discussion:
    1. How to establish the validity of pseudo-magnetic field synoptic maps (PMFSM)?
    2. Uncertainties? Verification of results based on PMFSM (methods/approaches)?
    3. How to extend the approach to early years when no CaK observations (nor sunspot polarities) were taken?
