Solar Wind Speed
Speed Ranges:
● Low (200-300) |
● Normal (300-500) |
● Elevated (500-700) |
● High (700-1000) |
● Extreme (1000+) km/s
For HF operators: High-speed solar wind (500+ km/s) can enhance auroral propagation but may disrupt normal HF communications.
For HF operators: High-speed solar wind (500+ km/s) can enhance auroral propagation but may disrupt normal HF communications.
Plasma Temperature
Temperature Ranges:
Update: 05:00
● Very Low (<100K) |
● Low (100K-300K) |
● Normal (300K-1M) |
● High (1M-2M) |
● Extreme (>2M) Kelvin
For HF operators: Higher temperatures (1M-2M K) and Extreme (above 2M K) often correlate with geomag disturbances that can affect HF propagation and create auroral enhancement on VHF/UHF.
