Solar Sun-As-A-Star Magnetic Field Data
Sun-As-A-Star measurements of the solar magnetic field are summed over the solar disk (the net magnetic field intensity in microTeslas). Several observations are made daily, centered around local noon. Each value reported is a weighted average of all measurements for that day. The weighting arises from effects that include solar rotation, limb darkening, and weakening of the sensitive absorption line within active regions.
