Hello Alan,

Thank you for the information.

I keep an eye on the Kyoto Dst and on he 17th it peaked +45.
Such a peek often preceeds a major drop, however this one was very 
fast and deep. After the minimum of -228, it rose almost as steep as 
it dropped to about -90. After that the recovering is much slower 
and at the same speed.

Is there an explanation for this?
