MAGNETOGRAPHS are dedicated instruments that observe the solar
vector magnetic field and provide a homogeneous record of the
changing solar field. The solar magnetic fields are
photographically or computer drawn contours of the solar
longitudinal magnetic field distribution across the whole sun at
different levels of nanotesla (gauss). The computer-plotted
contours use solid lines for positive and dotted lines for
negative field polarities. The polarities on the photographs
are indicated by bright areas (positive) and dark areas
(negative). The data also can be drawings of individual sunspot
regions with coordinates, polarity and intensity in nanotesla of
each spot indicated.
