Synoptic Frame
All or part of a solar image remapped to standard synoptic heliographic coordinates defines a synoptic frame.
A number of individual magnetograms can be combined to construct a synoptic frame, but a frame effectively represents a snapshot of some appreciable part of the visible disk at a particular time.
A synoptic frame is a subset of a complete SynopticMap. A synoptic frame can be inserted into a synoptic map to produce a synchronic frame.
A series of [:SynopticMap:synchronic frames] can be useful for studying the effects of time evolution of the solar magnetic field in a global context.
