NEOCP Explorer v3.1

NEOCP Explorer v3.1

Renamed from "NEO Tracker" to NEOCP Explorer, with important fixes to the
orbit determination.

Fixes

• No more false "interstellar object" flags. The Find_Orb query now forces
  heliocentric elements (element_center=0). Previously, short-arc near-Earth
  NEOCP objects returned a geocentric solution ("Perigee"/"J2000 equator")
  whose eccentricity is relative to Earth (e ≫ 1), raising a false interstellar
  alarm and hiding the real Earth MOID / Earth-crossing detection.
• Negative semi-major axis handled correctly for genuinely hyperbolic
  heliocentric orbits (a < 0), now classified as "Hyperbolic / unbound".

Improvements

• Eccentricity now shows its uncertainty (e ± σ) and flags poorly constrained
  (short-arc) orbits. The hyperbolic/interstellar alarm only fires when the
  hyperbolic excess is statistically significant (e − 3σ > 1).

Download

• NEOCP_Explorer.exe — Windows, standalone (no Python or local Find_Orb required).

NEO Tracker v3.0 — Online Project Pluto Engine

NEO Tracker v3.0 — Online Project Pluto Engine

This release removes the need for a local Find_Orb installation.

Major changes

• Removed local fo64.exe / Find_Orb dependency.
• Removed config.ini.
• Added Project Pluto online Find_Orb backend.
• Unified workflow for known NEOs and NEOCP candidates.
• Added local Alt/Az/Airmass calculation with Astropy.
• Added apparent motion rate in arcsec/min and motion PA.
• Improved ephemeris table formatting.
• Added cleaner error handling for invalid objects or unavailable ephemerides.
• Added parser regression tests for Project Pluto responses.

Requirements

The executable version does not require Python.

For source usage:

pip install -r requirements.txt

NEO Tracker v2.1 — Bug Fixes & NEO Classification

What's changed

Bug Fixes

• NEO mode fully restored: observations were silently dropped due to a packed-designation mismatch in the OBS80 filter (e.g. 2024 MK2 → K24M02K), producing an empty file and fo64.exe exit status 1. Filter is now restricted to NEOCP only.
• Submit button deadlock fixed: a non-integer value in Ephemeris steps left _processing = True permanently, silently locking the Submit button for the rest of the session.
• Validation error highlight now visible: ttk.Entry requires style-based theming (Error.TEntry); the previous .configure(background=...) had no visual effect.

Improvements

• NEO classification rewritten: dynamical class now uses Tisserand relative to Jupiter (T_J) with explicit fallback. NEO sub-class (Atira / Aten / Apollo / Amor) derived from orbital elements.
• Ephemeris altitude column corrected: parser was reading Position Angle (PA) instead of altitude, yielding impossible values > 90°.
• "Close Approach" renamed to Min. Distance in Ephemeris Window to accurately reflect what the section computes.

Housekeeping

• app.log removed from git tracking
• .gitignore rewritten
