Stefan,

Thank you for your findings on 630m SNR vs. time during magnetic disturbance
onset. The resolution of your data and your narrative details highlight
fascinating characteristics.

73,

Jim AA5BW

MF,

Very interesting, while the DST stuff
(http://lasp.colorado.edu/space_weather/dsttemerin/dsttemerin.html)
peaked down to -50nT and LF was nearly dead, there was an open path on MF
between DL and the US west coast. Often we can find a quite small opening
window on 630m for TA contacts, sometimes just 10 minutes or so, during
sunset in the US. However last night the window was open until 6 UTC and
then closed instantly. I took the chance and sent WSPR-2 in 33% mode and got
a nice set of data for the attached SNR plot.

BTW congrats to the other stations for the good results!

73, Stefan/DK7FC
