LF: RE: The Great Space Weather Storm of May 1967

[<hvanesce@comcast.net>]

Thanks Louis,

 

I hadn’t realized it’s the semicentennial of that great storm; in the long run much good came directly/indirectly from subsequent research, including space weather instruments and models.

 

By that time I had upgraded from the superregenerative RX to BC453/4/5 and RME 4350, which with a Handbook-derived 807 TX and 300-ohm twinlead folded dipole allowed interesting QSOs in late May (I know where my log book is, that might be interesting)

 

One of the memorable findings from the storm:  strong coherent global oscillation of 5 kHz  to 8 kHz VLF emissions (originating in the magnetosphere), time-synchronized in U.S., Europe, and Japan (Harang 1968)

 

Thanks for the reminder; hope we can continue to make good use of equipment, data and models that began to evolve after the storm.

 

73,

 

Jim AA5BW

The strongest recorded event so far, just 50 years ago

Dst =-387nT, Kp=9 for 6 hours

Flare flux: 8000 SFU at 2800MHz

 

Dolores J Knipp (Univ of Colorado) recently gave the following talk on the subject at the  American Meteorological Society’s 14th Conference on Space Weather
