Steinar,
 
thanks for reporting this! The 0.1 Hz Doppler shift is remarkable. Is your frequency scale upright or inverted?
 
On a several occasions a few years back, I observed still unexplained "ripples" on SXV 135.8 kHz, which seemed to indicate a delayed component with a similar-sized Doppler shift:
 
What is strange is that according your screenshot the shifted trace appeared from 4:15 to 4:45 UT, whereas the Boulder magnetometer shows a magnetic disturbance starting not before at 6:00: 
 
BTW I wonder if LA4ANA's beacon would be detectable on one of our 137780 Hz microHz grabbers here. Do you know his exact frequency, and whether the carrier is phase continuous?
 
Best 73,
Markus

I think I picked it up with my 137Khz grabber. I am monitoring Robert
LA4ANA on 137780. It is ground wave between us, but I think I can see an
sky wave refection also when the storm hit the earth. What do you think?
