NOAA Station A and K Indices

• The bar graphs show the degree of geomagnetic disturbance.
• The A and K indices are related, but the K index will be a more up-to-date indication.
• For the K index, lower is better and zero is great.
• The Boulder K index is also available from radio station WWV hourly at :18 on 2.5, 5 and 10 MHz.

• For the amateur who would like to go more in depth on the subject of HF propagation, prediction and interpretation of data available from numerous sources, the webmaster recommends The NEW Shortwave Propagation Handbook. Amazon offers it for $20.99. It is written by George Jacobs, W3ASK and Dr. Ted Cohen, N4XX. George Jacobs has for several decades written the monthly propagation column in CQ.
