Below you will find charts showing the live conditions around the Earth for radio propagation as well as atmospheric conditions that can affect Ham Radio usage depending on frequency. These are great tools for HF and knowing what the conditions are if you plan on trying to make contacts on a particular day/time.

Key for These Charts
The three main items you want to pay attention to are the SFI (Solar Flux Index), the A-Index and the K-Index.
SFI – Summarization of the
Sun’s Radiation Output
A-Index – Daily Average of
Magnetic Activity
K-Index Updated every 3 Hours
- 70 – Not Good
- 80 – Good
- 90 – Better
- 100+ – Best
- A = 0 – 7 Quiet
- A = 8 – 15 Unsettled
- A = 16 – 29 Active
- A = 30 – 49 Minor storm
- A = 50 – 99 Major storm
- A = 100 – 400 Severe storm
- K = 0 Inactive
- K = 1 Very quiet
- K = 2 Quiet
- K = 3 Unsettled
- K = 4 Active
- K = 5 Minor storm
- K = 6 Major storm
- K = 7 Severe storm
- K = 8 Very severe storm
- K = 9 Extremely severe storm

Please note: These charts are not a 100% accurate representation of the band conditions. They are, however, a basis for what you “can” expect with the band conditions. You may see better or worse results based on your location. The charts are automated and update on their own. They will give you a good idea of the current conditions, but again, they are a baseline, not gospel.
