▶ How to read this
Why do I care about aurora?
Aurora = geomagnetic storm. Great for VHF scatter and 6m openings, but it trashes HF propagation. High Kp (5+) means skip is disrupted, especially on 20m and above.
What are these sun pictures?
NASA's Solar Dynamics Observatory captures the sun in different wavelengths. Bright spots = active regions that boost ionization and improve HF propagation. Dark spots on the magnetogram show sunspots.
What's the Kp index?
Measures geomagnetic disturbance on a 0-9 scale. 0-2 = quiet (good HF). 3-4 = unsettled. 5+ = storm (HF disrupted, VHF enhanced).

▶ How to read this
What are these satellites?
Amateur radio satellites with transponders you can actually talk through using a handheld or small yagi. The ISS even has a repeater onboard.
What does "above horizon" mean?
If a satellite's elevation is above 0° from the station's location, it's potentially workable. Higher elevation = stronger signal. Passes last about 10-15 minutes.
What are the ground tracks?
The dotted lines on the map show where each satellite will travel over the next 90 minutes. Positions update in real-time so you can watch them move.
