Open Reporting → Usage in Operations. Select the last 7, 30, 90 or 365 UTC dates and optionally select spacecraft. Without a spacecraft filter, the report includes historical activity from archived spacecraft.

​
Event activity

The Events section shows separate totals and daily charts for: Created events use their creation/publication date. Bookings use the date you saved them. Neither uses the scheduled date of the overflight or contact. A booking does not establish that an observation or contact was executed. AOI and ground-station reporting follow the same rules. Refreshing forecasts or deleting their source records does not subtract historical usage. Newly published replacement forecasts add creation activity, so these counts are not counts of unique physical encounters. Repeated requests for an existing booking and its archive copy do not add another booking.

​
Reading historical coverage

Each metric states whether its history covers the selected period. Partial history means the displayed total is a subtotal starting at the shown UTC time; earlier activity is unavailable. A partly tracked first day is marked partial in the chart. Dates before tracking began are not plotted as zero. No activity means tracking was available but recorded nothing for your selection. History unavailable means the report cannot establish activity for that period. A failed request shows a separate error and Retry action.
