AURORA

Aurora Borealis power history from NOAA geomagnetic data. Watch the Northern Lights dance through 6 hours of real activity. Flow field particles mimic the aurora's natural movement patterns using NOAA's Ovation Aurora data.

Features

• NOAA data: Real geomagnetic activity measurements
• Flow field physics: Particle-based aurora simulation
• 6-hour history: Recent aurora power readings
• Color gradient: Aurora green (#00ff6a) to cyan (#00f5ff) to magenta (#ff38c7)
• Interactive: Hover to see data points
• Responsive: Works on desktop and mobile

Technical Stack

• D3.js v7: Data-driven rendering
• SVG: Vector graphics for smooth scaling
• Space Grotesk font: Modern geometric sans-serif
• DM Mono: Monospaced data display
