Understanding Solar Wind
Solar wind is a stream of charged particles released from the Sun's corona. It travels at speeds of 300-800 km/s and takes 2-4 days to reach Earth.
<400 km/s
Slow - quiet conditions
400-500 km/s
Normal
500-700 km/s
Elevated - minor activity
>700 km/s
High - storm potential
Understanding IMF Bz
IMF Bz is the north-south component of the Interplanetary Magnetic Field. When Bz turns southward (negative), it can connect with Earth's magnetic field and trigger aurora.
Bz Positive (North)
Field repels - aurora unlikely
Bz Near Zero
Neutral - variable conditions
Bz Negative (South)
Field connects - aurora favorable!
Current Aurora Conditions
Based on real-time space weather data
Quiet Conditions
Current conditions are quiet with low aurora probability. Aurora may still be visible at very high latitudes (65°N+).

What is Solar Irradiance?
Solar irradiance represents the total solar energy received per square meter over a single day at your specific location, based on NASA satellite data. It is a key metric for assessing solar power generation potential and for environmental studies.
Unit: kWh/m²/day
This measures how much solar energy hits each square meter of Earth's surface daily. Values typically range from 1-8 kWh/m²/day depending on location, season, and weather conditions.
Surface Temperature
This is the temperature of the top layer of the ground, as measured by satellites. It differs from the air temperature and indicates the direct impact of solar radiation on the surface. This measurement is useful for understanding local climate conditions and energy balance.

HF Radio Blackout Map
D-Region Absorption Prediction (D-RAP)
This map shows the D-Region Absorption Prediction (D-RAP), which indicates areas where high-frequency (HF) radio communications may be degraded or completely blacked out due to increased ionization caused by solar X-ray and particle events.
The color bar under NOAA's map is the highest frequency weakened by absorption, from 0 to 35 MHz. Under the sun, about 15 MHz matches an R1 (Minor) radio blackout and 25 MHz an R3 (Strong). In red and orange areas HF signals (3-30 MHz) are strongly attenuated or lost, affecting aviation, maritime, and amateur radio communications.
