INTERNATIONAL MERCURY WATCH
An informal consortium of observers using remote sensing techniques to conduct campaign-focused studies of the source regions and morphology patterns of Mercury’s exosphere.
Mission Statement
INTERNATIONAL MERCURY WATCH
Teams of Observers from Japan, France, Italy and USA
Observations primarily groundbased using sodium emissions.
New opportunities from spacebased imagers. Organized as part of PHEBUS on the
BepiColombo Mission. Near-term relevance to MESSENGER Mission.
INTERNATIONAL MERCURY WATCH
Scientific Goals and Objectives Identify the spatial and temporal scales of source
regions for Mercury’s exosphere. Combine multi-technique observations to constrain
uncertainties inherent in single-parameter observations.
Characterize solar radiation acceleration effects upon sodium atoms in exospheric tail at all points in Mercury’s orbit.
Use case-study data sets to constrain models of Mercury’s exosphere.
Provide timely input to BepiColombo and MESSENGER colleagues and mission planners.
INTERNATIONAL MERCURY WATCH
Observing Strategies Participating teams make observations
according to their own plans and objectives throughout each year (with support from national sources).
Participating teams agree upon at least one Joint Observing Period each year, typically spanning ~1 week.
This plan provides data sets appropriate for studies of long-term variability and shorter-term case-studies.
INTERNATIONAL MERCURY WATCH
Presentation of Results • Encourage individual teams to present
and publish single data set results.
• Encourage and coordinate case-study presentations and publications of campaign-mode, multi-diagnostic results.
