These maps show magnetic flux emanating from
the photosphere as gray coding against the sun's full latitude and
Carrington longitude ranges. The maps are available once per Carrington
rotation and also, from a separate subdirectory, at "daily" (more
typically, once every several days) resolution. For some intervals,
the data are available as both jpegs for browsing and as gzipped
FITS-formatted files for quantitative work.
