Key POLARIS events are logged by date, time and station code. Normal events include starting new station, swapping Libra VSAT terminal and digitizer (electronics), swapping seismometers, rare change of station code, change of sample rate, upgrading remote station firmware software and so on. These events are indicated by light-blue and white colors.
Events that lead to network interruption and data loss are also logged and indicated by red color.
