HELIOS-CORTEX ☀️ Solar Flare Intelligence System Real-Time Nowcasting & Predictive Forecasting for Aditya-L1 🇮🇳 Bhartiya Antariksh Hackathon 2026

🌞 THE SUN NEVER SLEEPS AND NEITHER DOES HELIOS-CORTEX We watch. We learn. We warn. 30 minutes before impact.

🚀 THE PROBLEM

⏱️ TIME	💥 IMPACT
T+0 min	Solar flare erupts on Sun's surface
T+8 min	X-rays reach Earth — GPS scrambles, power grids surge
T+15 min	Communications blackout begins
T+30 min	Full infrastructure impact — satellites, navigation, everything

💡 OUR SOLUTION By fusing data from TWO Aditya-L1 instruments, we detect flares 30–60 minutes BEFORE they hit Earth.

🧬 THE SECRET SAUCE

The Neupert Effect — Our Key Insight 🛰️ HEL1OS → Hard X-rays spike FIRST 🛰️ SoLEXS → Soft X-rays rise LATER 🎯 RATIO = 30 min EARLY WARNING

FEATURE	DESCRIPTION	ADVANTAGE
🔍 Multi-Instrument Fusion	SoLEXS (thermal) + HEL1OS (non-thermal) cross-correlation	Catches pre-flare signatures
🎯 Adaptive Thresholding	MAD-based rolling threshold	Zero false alarms during solar max
🧠 Transfer Learning	28+ years of NOAA GOES pre-training	Works with only 142 Aditya-L1 samples
⚡ Cascade Architecture	Nowcasting + Forecasting separated	Optimized for each task
🇮🇳 India Risk Map	34 states/UTs with GPS & power grid GIC modeling	Regional impact assessment
