In the Plans for the SOHO Solar Maximum Science program section, a basic set of measurements used to characterize the dynamic Sun is defined and science plans for the rise to maximum and the period following maximum are presented. A brief Implementation plan describes how we will save development costs by achieving the Solar Maximum Science program goals with existing capabilities. In the Scientific Impact Section, we summarize some of the most interesting results from the mission so far, and what we hope to achieve in the SOHO Solar Maximum Science program. In addition MDI takes data optimized for coordinated observations with the other SOHO experiments. It also provides direct measurements of surface motions from meso-granulation through to global scales.
Continuous observations are necessary for some of the primary helioseismology objectives.
There are two fundamental rea- sons for this. The first, is that the g -mode signal, if present in the surface oscillation, has a submillimeter amplitude in the individual modes.
