## Overview

HELIOSICA (**He**liospheric **E**vent and **L**1 **I**ntegrated **O**bservatory for
**S**olar **I**ntelligence and **C**oronal **A**ctivity) is an open-source physics-informed
framework that integrates nine governing parameters of the solar-terrestrial interaction
chain into a unified real-time storm severity solver.

The framework addresses a critical operational gap: current space weather systems provide
only 15--60 minutes of warning at the L1 Lagrange point, with no systematic
CME-departure-stage predictive capability. HELIOSICA extends this to **24--48 hours** from
coronagraph observations at solar departure, while simultaneously providing satellite
orbital safety metrics not available from any existing operational product.

**Validated against 312 geomagnetic storm events (1996--2025)**, covering two complete
solar cycles (SC23 and SC24) and the ascending phase of SC25.

## The SPIN Framework

The Solar Plasma Intelligence Nonet (SPIN) integrates nine parameters spanning the
complete physical causal chain from the solar corona to the magnetospheric response:

| # | Parameter | Symbol | Physical Domain | Role in Storm Prediction |
|---|-----------|--------|-----------------|--------------------------|
| 1 | CME Launch Velocity | V0 | Solar Corona MHD | Initial ejecta speed at 21.5 solar radii; drives DBM transit. Range: 250-3,000 km/s |
| 2 | Southward IMF Component | Bz | Heliospheric MHD | Negative Bz determines reconnection rate. Range: -50 to +50 nT. G5 threshold: < -30 nT |
| 3 | Solar Wind Ram Pressure | P_ram | Plasma Dynamics | P_ram = mp * np * Vsw^2. Range: 1-50 nPa. Nominal: 2-3 nPa, Extreme: 30+ nPa |
| 4 | Drag Interaction Coefficient | gamma | Interplanetary Plasma | gamma = k / (omega^2 * np). Units: km^-1. Inferred from CME geometry and ambient density |
| 5 | CME Angular Spread | omega | Heliospheric Geometry | Half-width of CME cone. Range: 30-360 deg (halo). Mean: 47 deg from SOHO/LASCO |
| 6 | Proton Thermal Temperature | Tp | Plasma Thermodynamics | Tp > 2x polytropic prediction = CME sheath. Range: 10^4 - 10^6 K. From DSCOVR Faraday cup |
| 7 | Reconnection Electric Field | Ey | Magnetopause Physics | Ey = Vsw * |Bz| for Bz < 0. Range: 0-50 mV/m. G5 threshold: > 12 mV/m |
| 8 | Forbush Decrease Index | Fd | Cosmic Ray Physics | Fd(%) = (J0 - J_min)/J0 * 100. Range: 1-15%. Fd > 3%: magnetic cloud core confirmed |
| 9 | Kp Geomagnetic Index | Kp | Magnetospheric Response | 3-hour planetary K index, scale 0-9. G1: Kp=5, G5: Kp=9. Primary validation target |

**GSSI composite** (Geomagnetic Storm Severity Index):

```
GSSI = 0.23*Ey* + 0.19*Bz* + 0.16*Pram* + 0.13*V0* + 0.10*gamma* + 0.08*omega* + 0.06*Tp* + 0.03*Fd* + 0.02*Kp*
```

Weights: w1=0.23 (Ey), w2=0.19 (Bz), w3=0.16 (P_ram), w4=0.13 (V0), w5=0.10 (gamma),
w6=0.08 (omega), w7=0.06 (Tp), w8=0.03 (Fd), w9=0.02 (Kp_baseline). Sum = 1.0.

GSSI thresholds: `< 0.20` G0-G1 | `0.20-0.45` G2-G3 | `0.45-0.70` G4 | `> 0.70` G5 (extreme)

## Quick Start

```python
from heliosica import DBMSolver, StormForecaster, MagnetopauseTracker, ForbushMonitor

# --- CME Transit Prediction (DBM) ---
solver = DBMSolver()
result = solver.predict(
    V0=1200.0,      # CME launch velocity (km/s) from SOHO/LASCO
    Vsw=450.0,      # Ambient solar wind speed (km/s)
    omega=60.0,     # CME angular half-width (degrees)
    np_cm3=8.0      # Upstream proton number density (cm^-3)
)

print(result.gamma)                 # Computed drag coefficient (km^-1)

# --- Real-Time Storm Forecasting ---
forecaster = StormForecaster()
storm = forecaster.evaluate(
    Ey=6.5,         # Reconnection electric field (mV/m) = Vsw * |Bz|
    Bz=-14.0,       # Southward IMF component (nT)
    Pram=12.3,      # Solar wind ram pressure (nPa)
    V=620.0,        # Solar wind velocity (km/s)
    theta_IMF=155.0 # IMF clock angle (degrees)
)
print(storm.Kp_pred)    # Predicted Kp value

```

## Module Reference

### `DBMSolver`

Analytical drag-based CME transit solver. Governing equation:

```
dV/dt = -gamma * (V - Vsw) * |V - Vsw|

Analytical solution: V(t) = Vsw + (V0 - Vsw) / [1 + gamma * |V0 - Vsw| * t]

Drag coefficient: gamma = k / (omega^2 * np)   [k = 2.0e-15 km^-1 * cm^3]
```

Monte Carlo ensemble: 10,000 members over (gamma, Vsw, V0) uncertainty distributions.
Execution: < 1 ms per deterministic call; < 10 s for full ensemble.
RMSE = 4.2 +/- 0.8 hours (41% improvement over WSA-Enlil RMSE of 7.1 hours).

### `StormForecaster`

Real-time Kp predictor and GSSI compositor. Ingests DSCOVR 1-min L1 streams or OMNI
archive. Master Kp predictor function:

```
Kp_pred = a1*ln(1+Ey) + a2*ln(Pram/P0) + a3*(V/V0)^beta + a4*cos(theta_IMF) + Kp_base
```

Coefficients (non-linear least squares, leave-one-year-out CV):
a1=1.82, a2=0.64, a3=0.41, beta=0.78, a4=0.35, Kp_base=1.0, P0=2.1 nPa.
Result: r2 = 0.91 against 312 validation events.
Latency: < 2 seconds from data ingestion to GSSI output.

### `MagnetopauseTracker`

Real-time standoff distance from pressure balance:

```
P_ram = mp * np * Vsw^2       [mp = 1.67e-27 kg]

R_MP = RE * (BE^2 / (2*mu0 * P_ram))^(1/6)
```

Nominal: 10-12 RE. Extreme (G5): < 5 RE.
Issues automatic satellite safety alerts when R_MP < 7.0 RE
(geosynchronous orbit 6.6 RE + 0.4 RE safety margin).

### `ForbushMonitor`

Automated Forbush decrease detection via CUSUM change-point algorithm on NMDB
neutron monitor streams. Estimates magnetic cloud field strength:

```
Fd(%) ~= 0.48 * B_cloud(nT) + 1.2
```

Issues cloud confirmation alert at Fd > 3%, extending storm duration lead time
by 2--4 hours beyond electromagnetic parameters alone.

## Validation Catalogue

The 312-event validation catalogue (`data/validation/catalogue_312events.h5`) covers:

- **47** major events (Kp >= 8, G4-G5)
- **89** strong events (Kp 7-7+, G3)
- **176** moderate events (Kp 5-6+, G1-G2)

Period: 1996--2025 (Solar Cycles 23, 24, and ascending SC25). All events have confirmed
CME source identification in the SOHO/LASCO catalogue and complete L1 plasma and
magnetic field coverage from ACE or DSCOVR.

Cross-validation protocol: leave-one-solar-cycle-out (train SC23+SC25 ascending,
test SC24) to avoid temporal autocorrelation.

## Research Hypotheses

All four hypotheses confirmed against the 312-event validation catalogue:

**H1 -- DBM Superiority:**
HELIOSICA DBM predicts CME arrival time at L1 with RMSE <= 5 hours, superior to
WSA-Enlil operational RMSE of 7.1 hours.
*Result: RMSE = 4.2 +/- 0.8 hrs. Confirmed.*

**H2 -- Ey Dominance:**
Reconnection electric field Ey = Vsw * |Bz| is the single most predictive parameter
for Kp, with standalone Pearson r >= 0.82.
*Result: r = 0.871 (p < 10^-80). Confirmed.*

**H3 -- Magnetopause Accuracy:**
R_MP derived from HELIOSICA ram pressure equation predicts magnetopause standoff
to within +/- 0.8 RE for all 47 major storms (Dst < -100 nT).
*Result: RMSE = 0.71 RE. Confirmed.*

**H4 -- Forbush Independence:**
Forbush Decrease Index Fd is statistically uncorrelated with Ey (|r| < 0.30),
confirming non-redundant cosmic ray channel information.
*Result: r(Fd, Ey) = +0.29. Confirmed.*

## Operational Warning Lead Time

| Warning Stage | Current Operational | HELIOSICA | Advance |
|---------------|--------------------|-----------|---------| 
| Stage 1: CME Departure (Sun) | None | 24-48 hours (DBM from coronagraph V0, omega) | Transforms from reactive to predictive mode |

## SPIN Correlation Matrix

Inter-parameter Pearson correlations across 312 validation events.
Dominant couplings: Ey-Bz (r=+0.87) and gamma-omega (r=-0.73) reflect fundamental
physical relationships. Near-independence of Fd from Ey (r=+0.29) confirms H4.

## Case Studies

Notebooks reproducing all published case studies are in `notebooks/`:

**Halloween Superstorm (Oct-Nov 2003)** -- `06_halloween_2003_casestudy.ipynb`

The most extreme validation event (Kp=9, Dst=-383 nT). Two CMEs from NOAA AR 10486.

- CME 1 (28 Oct): V0 = 2,029 km/s, omega = 360 deg. DBM error: 0.2 hrs.
- CME 2 (29 Oct): V0 = 2,459 km/s, omega = 360 deg. DBM error: 0.3 hrs.
- Peak Ey = 22.4 mV/m (1.9x above G5 threshold of 12 mV/m).
- Peak P_ram = 34.8 nPa. Predicted R_MP = 5.2 RE (actual 5.1-5.5 RE). Discrepancy: 0.1-0.3 RE.
- Fd = 7.8% at Oulu. Predicted B_cloud = 13.5 nT; actual 14.2 nT (6% discrepancy).
- GSSI = 0.88. Category: G5. Full agreement across all six independently validated parameters.
- Real-world: destroyed Midori-2 satellite, damaged 13 others, power outages in Sweden.

**St. Patrick's Day Storm (17 March 2015)** -- `07_stpatricks_day_2015.ipynb`

Strongest storm of Solar Cycle 24 (Kp=8, Dst=-223 nT). First event fully within DSCOVR period.

- CME source: AR 12297, 15 March 2015. V0 = 769 km/s.
- DBM error: 0.6 hrs. Kp prediction: 7.8 +/- 0.6 (actual 8, within 1-sigma).
- GSSI = 0.61 (G4 boundary). R_MP = 7.1 RE -- no false satellite safety alert.

**Solar Minimum Baseline (2019-2020)** -- `08_solar_minimum_2019_2020.ipynb`

Deepest solar minimum of the space age; extended periods of zero sunspot number.

- GSSI below 0.15 for 91% of 18-month period. All 4 G1 events correctly identified.
- Mean quiet GSSI: 0.08 +/- 0.04. Oulu GCR +8% vs solar max, correctly tracked as background.
- Provides highest-quality Forbush background calibration window in the 1996-2025 catalogue.

**Carrington Event Reconstruction (1859)** -- `09_carrington_reconstruction.ipynb`

First physically grounded HELIOSICA quantitative assessment of a Carrington-class event.

- Transit time ~17.6 hours implies V0 ~= 2,200-2,600 km/s (DBM solved in reverse).
- Estimated Dst: -850 to -1,760 nT implies Ey ~= 50-100 mV/m.
- GSSI ~= 0.92 +/- 0.08 (well above G5 threshold 0.70).
- Predicted R_MP: ~3.8-4.4 RE -- well inside geosynchronous orbit (6.6 RE).
- Historical aurora at Cuba (19N) and Hawaii (20N) consistent with R_MP below 3.5 RE.
