Interesting times on 6m
tonight. I spent a pleasant hour bouncing signals off the
Aurora. There were many stations calling from all over the US and this
was the first time I have ever heard the Aurora Flutter.
Aurora Flutter normally
occurs when radio signals are reflected from the auroral curtain. SSB
signals that are reflected sound very raspy, sound like the other operator is
talking in a quiet whisper, and are difficult to understand and tune in.
At 2300 UTC the A Index
was at 100 and the K Index was 7. I have never seen the A Index that high
before.
