Parker Solar Physics Engine

A real-time 3D magnetohydrodynamic simulation of our Sun — from sub-surface convection cells to the heliospheric current sheet and beyond. Solar wind acceleration follows Parker's 1958 spiral model, with live NOAA/SWPC data driving X-ray flux, active region positions, and geomagnetic storm indices.

☀️
Corona & Wind
The solar corona reaches 1–3 million K via Alfvén wave heating. Wind particles accelerate outward along the Parker spiral — a direct consequence of the Sun's rotation coupled with radial outflow. Typical solar wind speed: 400–800 km/s.
🔴
Active Regions & Flares
Active regions (sunspot groups) are mapped using live NOAA data and rendered as 3D magnetic flux concentrations. Flare class (A→X) is pulled from GOES X-ray flux. X-class events trigger the corona bloom and ribbon alert animations.
💨
CME & Particle Events
Coronal Mass Ejections are drawn from the DONKI catalog with estimated arrival times at L1. Solar Energetic Particle (SEP) events and radio blackout levels (NOAA R1–R5 scale) are displayed in the right panel.
🌐
Heliospheric Current Sheet
The wavy HCS separates inward and outward magnetic field sectors. Its geometry is driven by solar tilt angle and Parker spiral physics. The simulation renders both the current sheet surface and the sector boundary crossings.

SDO Live Imagery
Real-time images from NASA's Solar Dynamics Observatory in multiple wavelengths: AIA 304 Å (chromosphere), AIA 171 Å (corona), AIA 193 Å, and HMI magnetogram (surface field).
📡
Live Data Sources
Data refreshes every 5 minutes from NOAA/SWPC. Sources: GOES X-ray flux, DONKI CME catalog, Solar Region Summary, 3-day particle flux, and ACE/DSCOVR solar wind measurements at L1.
