IN THE PROPOSED WORK WE CONTINUE AND EXTEND OUR EFFORTS OF THE PREVIOUS THREE YEARS (26WIND PUBLICATIONS IN 2013-2016; AND 3 IN THE REVIEW PROCESS) IN VARIOUS AREAS OF HELIOSPHERIC AND MAGNETOSPHERIC PHYSICS. THE MAGNETOSPHERIC ASPECT INVOLVES WIND AS L1 MONITOR OF INTERPLANETARY CONDITIONS WHEN INVESTIGATING HOW MAGNETOSPHERIC-IONOSPHERIC COUPLING PROCESSES AND THE STRUCTURE OF RECONNECTION LAYERS ARE CONTROLLED BY INTERPLANETARY PARAMETERS. TOPICS INCLUDE (I) TRADITIONAL AND NON-TRADITIONAL ASPECTS OF SUBSTORM EVOLUTION; (II) THE EFFECT OF A LARGE GUIDE FIELD ON THE STRUCTURE OF THE DISSIPATION REGION IN COLLISIONLESS RECONNECTION AND (III) GEOEFFECTS ELICITED BY SMALL SOLAR WIND TRANSIENTS (STS) PARTICULARLY THOSE WHICH DEPEND ON FACT THAT STS ARE MAGNETICALLY-DOMINATED STRUCTURES (LOW ALFV EN MACH NUMBER). WORK ON THE GEOMAGNETIC TAIL IS ALSO PROPOSED USING DATA ACQUIRED BY WIND DURING PASSAGES THROUGH AND NEAR THE GEOMAGNETIC TAIL. SPECIFICALLY WE INVESTIGATE: (I) A FLUX ROPE STRUCTURE SEEN BY WIND IN THE DISTANT TAIL AND PRECEDING AN INTERVAL OF TAIL FLAPPING IN THE CONTEXT OF SIGNATURES OF TRAVELING CONVECTION VORTICES SEEN BY VARIOUS MAGNETOSPHERIC PROBES AT THE SAME TIME. (II) EFFECT OF THE ANGLE BETWEEN THE SOLAR WIND VELOCITY AND THE IMF ON THE STRENGTH OF DRAPING-RELATED MAGNETOSHEATH ACCELERATION IN THE DISTANT TAIL. IN THE INTERPLANETARY AREA WE PROPOSE WORK ON CERTAIN ASPECTS OF SMALL SOLAR WIND TRANSIENTS AT 1 AU: A COMPREHENSIVE SURVEY OVER 2 SOLAR CYCLES USING WIND AND STEREO DATA; DEPENDENCE OF THEIR OCCURRENCE FREQUENCY ON BOTH SOLAR CYCLE PHASE AND SOLAR WIND SPEED; AND THEIR ANALYTICAL MODELING AND HOW THE MODELS CHOSEN (FORCE FREE VERSUS NON-FORCE FREE) DEPEND ON SOLAR CYCLE PHASE. WE WILL TAKE ALL OPPORTUNITIES TO USE WIND OBSERVATIONS IN THE CONTEXT OF MAGNETOSPHERE MULTISCALE (MMS) MISSION STUDIES OF THE RECONNECTION REGION ON THE DAYSIDE AND IN THE TAIL. THE STRUCTURE OF THE DISSIPATION REGION IS KNOWN BE DISTORTED BY ASYMMETRIES IN THE DENSITY AND MAGNETIC FIELDS AND THE PRESENCE OF A GUIDE FIELD. ON THESE WIND CAN PROVIDE IMPORTANT INFORMATION. THE PROPOSED WORK WILL ENHANCE THE SCIENTIFIC RETURNS OF THE WIND MISSION. PROVISION IS ALSO MADE TO MAINTAIN THE SWE/ELECTRON INSTRUMENT WHICH PROVIDES VALUABLE DATA TO THIS EFFORT.
