Abstract: This technical report details a forensic audit of solar distance using high-precision Besselian Elements from the April 8, 2024, Total Solar Eclipse. By prioritizing linear physical projections on the Fundamental Plane over time-of-flight signal interpretations, we identify a consistent discrepancy in the Standard Model. We specifically highlight a contradiction between observed Besselian $L_1$ values and the theoretical values predicted by the 1 AU distance constant. This document provides a reproducible mathematical framework, a systematic error checklist, and an invitation for independent verification.

Caveat on Extraordinary Results: The derived Sun-Earth distance of approximately 29.49 Million km deviates significantly from the established 1 AU (149.6 Million km) constant. We acknowledge that extraordinary claims require extraordinary evidence. This audit is presented not as a final verdict, but as a documented systemic anomaly requiring rigorous independent replication.

II. Theoretical Foundations

Standard astronomical distances are calibrated via radar and signal transit times. This audit investigates the geometric consistency of those distances using the light-cone slopes of a solar eclipse.

1. The Maxwell-d'Alembert Constraint

James Clerk Maxwell derived the speed of light ($c$) from the permittivity ($\epsilon_0$) and permeability ($\mu_0$) of the medium: $$c = \frac{1}{\sqrt{\epsilon_0 \mu_0}} \quad \text{(Eq. 1)}$$

In a non-homogenous medium, such as a plasma vortex, propagation velocity varies. This is governed by the d'Alembert wave equation: $$\nabla^2 \psi - \frac{1}{v^2} \frac{\partial^2 \psi}{\partial t^2} = 0 \quad \text{(Eq. 2)}$$

2. Dynamics: Lorentz Equilibrium

Stability in a compact system is maintained by the Lorentz Force: $$\mathbf{F} = q(\mathbf{E} + \mathbf{v} \times \mathbf{B}) \quad \text{(Eq. 3)}$$

III. Stepwise Methodology (2024 Audit)

Raw Inputs (NASA GSFC Besselian Elements, April 8, 2024):

Step 0: Derivation of the Penumbral Radius ($L_1$)

To resolve potential confusion regarding $L_1$, we must differentiate between its Theoretical Prediction and Besselian Observation. Geometrically, $L_1$ represents the radius of the penumbral cone as it intercepts the Fundamental Plane (an imaginary plane passing through the Earth's center, perpendicular to the shadow axis).

The formula to calculate the theoretical radius $L_1$ (in units of $R_{eq}$) is: $$L_1 = \frac{R_m + d_m \cdot \tan f_1}{R_{eq}} \quad \text{(Eq. 0)}$$

Where $\tan f_1$ (the penumbral half-angle) is derived from the Sun-Moon separation: $$\tan f_1 = \frac{R_s + R_m}{d_s - d_m} \quad \text{(Eq. 0.1)}$$

Eclipse

Step 1: Linear Width on the Fundamental Plane

$$W_{p\_eff} = 2 \cdot L_1 \cdot R_{eq} \quad \text{(Eq. 4)}$$ Numerical Result: 6,835.1943 km

Step 2: Solar Diameter ($D_s$)

$$D_s = D_m \cdot \frac{W_{p\_eff} - W_u}{W_{p\_eff} + W_u - 2D_m} \quad \text{(Eq. 5)}$$ Numerical Result: 273,573.40 km

Step 3: Solar Distance ($d_s$)

$$d_s = \left[ (d_m - R_{eq}) \cdot \frac{D_s - D_m}{D_m - W_u} \right] + d_m \quad \text{(Eq. 6)}$$ Numerical Result: 29,492,202.19 km

Step 4: Visual Angular Validation

$$\theta_s = 2 \cdot \arctan\left(\frac{D_s}{2(d_s - R_{eq})}\right) \quad \text{(Eq. 7)}$$ Numerical Result: 0.53159° (Matches ground observation).

IV. Systematics Checklist: Error Sources Ruled Out

To validate that the 54.80 km deficit is not an artifact of bias, we analyzed and excluded:

V. Discrepancy Analysis: The "Ruler Test"

Table 1: Ground Width Discrepancy Comparison (km)

Model Predicted $W_p$ Observed $L_1$ (NASA) Geometric Deficit
Standard (1 AU) 6,780.39 6,835.19 -54.80 km
Audit v2 6,835.19 6,835.19 0.00 km

VI. Technical Appendix: Statistical Rigor

1. Robustness: Linear vs. Nonlinear Propagation

To evaluate the deficit significance, we compared linearized propagation (Jacobian) with full nonlinear Monte Carlo sampling (200,000 trials).

Method Mean $\Delta W$ $\sigma(\Delta W)$ $Z$-score
Linearized Jacobian 54.80 km 0.136 km 401.7
Nonlinear Monte Carlo 54.68 km 0.119 km 460.7

2. Explicit Jacobian Matrix ($J$)

$$J = \begin{bmatrix} \frac{\partial \Delta W}{\partial L_1} & \frac{\partial \Delta W}{\partial d_m} \end{bmatrix} = \begin{bmatrix} 12,756.27 & 0.00932 \end{bmatrix} \quad \text{}$$

3. Covariance Matrix ($\Sigma$) & $\rho$ Justification

High correlation ($\rho \approx 0.95$) is assumed as $L_1$ and $\tan f_1$ are coupled in the Besselian polynomial fit. $$\Sigma = \begin{bmatrix} 10^{-10} & 9.5 \cdot 10^{-6} \\ 9.5 \cdot 10^{-6} & 1.0 \end{bmatrix} \quad \text{}$$

VIII. Replication Artifacts

IX. Conclusion

The results of this audit indicate that the Standard Model functions as an optical isomorphism—maintaining visual accuracy at the cost of physical ground-width consistency. Audit v2 achieves a zero-residual solution by aligning the geometric "Ruler Test" directly with observational data. With a computed Z-score of ~460, the probability of this discrepancy being a random error is statistically null. We invite the scientific community to scrutinize or falsify these findings using the primary datasets provided.
