  1. Quiet Sun magnetic fieldsand the Total Solar Irradience (TSI) RoaldSchnerr (Stockholm) Henk Spruit (MPIA)

  2. TSI and the Solar cycle Fröhlich et al.

  3. Magnetic fields and irradience Intensity End Start Solar max Magnetic field Sheeley & Warren 2006

  4. TSI predictions from synoptic data Magnetic field Intensity Free parameter: facular filling factor Wenzler et al 2004

  5. TSI modelling Wenzler et al 2004

  6. Quiet Sun fields MHD sims of Quiet Sun with different B (Vögler 2005)

  7. SST & Hinode Colours: [B,G,R] = [80<B<400, 400<B<700, B>700] (SST) [B,G,R] = [30<B<250, 250<B<650, B>650] (Hinode)

  8. Magnetic field statistics SST active region Hinode Quiet Sun Intensity vs B field, corrected for the “dark lane effect”

  9. Resolution vs TSI prediction
