Current HF & VHF Solar Conditions

Guide to Chart Symbols and Legends

When researching the propagation conditions, it’s essential to focus on three critical elements: the Solar Flux Index (SFI), the K-Index, and the A-Index. These indices serve as key indicators of the current state of ionospheric conditions, influencing radio wave propagation and, consequently, the effectiveness and reliability of radio communications. By closely monitoring these metrics, operators can better predict and understand the dynamics of radio signal travel, enhancing their ability to establish and maintain clear communications over various distances.

SFI (Summarization of the Sun’s Radiation Output)

70 = Not Good
80 = Good
90 = Better
100+ = Best

A-Index (Daily Average of Magnetic Activity)

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-Index (Updated every 3 Hours)

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
