Website history
Only visible content, layout, and navigation changes are listed. Each entry links directly to the affected public page.
People is now one navigation entry and one complete directory; only total MPEC counts link to person pages, where role filters remain available. Visible on: People · Statistical tables
Malformed nested MPC station links and the historic Obsever typo are now parsed without merging station names or losing observers. Visible on: Stations directory · G96 station page
Each station in Stations by discovery MPECs now links from its All MPECs value to the matching row in Stations by MPECs. Visible on: Stations by discovery MPECs · Stations by MPECs
People navigation now uses only the two combined directories; each person page can filter All, Observer, or Measurer next to the MPEC-type filters. Visible on: People by MPECs · People by name
Person timelines now enlarge on click and use horizontal labels close to the x-axis; person and station pages fill the available browser width responsively. Visible on: Person detail example · Station detail example
Charts is now a separate navigation page without a duplicate download section; Downloads remains its own entry. Visible on: Charts
Titles of single-object MPECs now open that object's MPC orbit page in the complete MPEC, station, and person lists. Visible on: All used MPECs · Station detail example · Person detail example
Discovery station pages now show the station-specific discovery timeline instead of the all-MPEC and observation charts; observer and measurer names link to existing person pages. Visible on: G19 discovery example
Person detail pages now offer Measurer, Observer, and Both role filters. Visible on: I. Kuettner example
Generated MPECSGET page footers now include the generation date and time in UTC. Visible on: Home
People now have complete observer and measurer directories plus station-style detail pages with summary cards, publication timelines, role filters, search, sorting, pagination, station links, and issued dates. Visible on: People by MPECs · People by name · Observer detail example · Measurer detail example
History now follows the Get-CP format with day headings, one paragraph per visible change, and a concise Visible on link list; earlier public changes have been reconstructed from retained project records. Visible on: History
Observer and measurer statistics now provide All, Top 10, Top 30, Top 100, complete search, sorting, column selection, Optimal, Reset, virtual All display, and links to the same canonical person in the other role. Visible on: Observers by MPECs · Observers by name · Measurers by MPECs · Measurers by name
The measurer directory has an explicit page heading and structurally complete table headings and body. Visible on: Measurers by name
The observer directory has an explicit page heading and structurally complete table headings and body. Visible on: Observers by name
The public History now contains only visible content, layout, and navigation changes with direct links to the affected pages. Visible on: History
Histogram scales automatically reduce the number of date labels when otherwise readable bar counts would still cause overlapping text. Visible on: Station pages
The station directory uses English Collapse and Expand labels, explains the double-click area, and adds row counts to TSV downloads. Visible on: Stations directory
Individually expanded station rows now remain open after the virtual station directory renders a new visible range. Visible on: Stations directory
Sorting the complete MPEC directory uses the full filtered data set in a background worker and shows progress while the order is calculated. Visible on: All used MPECs
The station directory adds Collapse and Expand, row-level double-click expansion, persistent choices, and Top 10, Top 30, Top 100, and All station rankings. Visible on: Stations directory · Stations by MPECs
Downloads show file sizes and, where meaningful, the number of data rows. Visible on: Downloads
MPEC charts count circulars by official publication date while observation charts count observations by observation date; both share the same comparison scale. Visible on: Station S03
Station MPEC tables and the complete MPEC directory add the official Issued date; the complete list also shows object and station counts. Visible on: All used MPECs
Database relations now link to their matching report tables and explain the meaning of each relation on hover. Visible on: Database
Station histograms now use real observation dates and the finest natural day, week, month, quarter, or year interval that stays within forty bars. Visible on: Station S03
Centimetre telescope apertures are normalized to metres, including the source-backed correction that removes the spurious 0.003-m telescope. Visible on: Instruments
A downloadable source table lists every original centimetre instrument spelling with its normalization, stations, and MPEC evidence. Visible on: Downloads
Instrument apertures are displayed consistently and single-object MPEC titles are emphasized on linked station pages. Visible on: Instruments
Person-name cleanup separates multiple roles and removes explanatory sentence fragments that were previously shown as people. Visible on: Observers by name · Measurers by name
Object MPECs are emphasized in station MPEC lists and remain distinguishable from Daily and other multi-object notices. Visible on: Station S03
Responsive station cards continue directly below the generation line and wrap cleanly beside the charts. Visible on: Station S03
Station charts stay at the upper right while metadata and tables flow in a separate non-overlapping content area. Visible on: Station S03
Station metadata is presented as responsive metric and detail cards instead of an introductory text block. Visible on: Station S03
Station pages add All, Object MPEC, and Other MPEC filters and apply the selection consistently to both the MPEC list and observed-object evidence. Visible on: Station S03
The complete MPEC table adds object count, station count, and official Issued date; single-object notices are emphasized. Visible on: All used MPECs
Equivalent telescope descriptions are combined, apertures use consistent metre notation, and all table headings remain sticky while scrolling. Visible on: Instruments
Orbital-element and precovery notices are recognized as identification notices instead of falling into Other. Visible on: All used MPECs
The selected MPEC category and list position now survive navigation back to the complete MPEC directory. Visible on: All used MPECs
Instrument spellings are mapped to the official MPC telescope vocabulary and retain downloadable source evidence for unresolved variants. Visible on: Instruments
A complete instrument directory now lists normalized telescope designations with linked observing stations and MPEC evidence. Visible on: Instruments
Person parsing removes date ranges, prose fragments, punctuation-only entries, unknown placeholders, and telescope text from observer and measurer names. Visible on: Observers by name · Measurers by name
MPEC title categories separate Daily updates, comet observations, editorials, comet notices, years, identifications, activity, corrections, satellites, monitoring, TNOs, and remaining object notices. Visible on: All used MPECs
Main index, station pages, people lists, and statistics now share one navigation, colour, spacing, focus, and table design. Visible on: Home · Stations by MPECs · Observers by name
The complete MPEC directory adds text search, category selection, year selection, paging, and an All view while retaining every record. Visible on: All used MPECs
Complete observer and measurer directories are available with linked detail pages and distinct MPEC counts. Visible on: Observers by name · Measurers by name
The main index now uses a left orientation bar and a shared visual structure for the complete public report. Visible on: Home
A database overview now explains the persistent MPEC, station, person, object, observation, and instrument relations. Visible on: Database
The station directory now uses all retained MPECs and lists station names, telescopes, observers, and measurers in a shared table. Visible on: Stations directory
Discovery markers and discovery totals now count a station only when that station is the actual discoverer; station codes sort as monospaced text. Visible on: Station S03 · Stations by discovery MPECs
