Hi, This may be of interest, In Larry's event list I have been posted 3 files which contain an interesting ULF radiation pulse that occurs many hours before a major event. Solar disturbances appear substantially different as sharp pulses with this instrument. 000912a.au4 (Indonesia region) Ms 6.1 000828b.au4 (Indonesia region) Ms 6.8 000827b.au4 (Volcano Island region) Mb 5.6 More observations are required but there seems to be some ULF radiation emitted a few hours before big quakes that are deeper than 33 km in certain regions. Soon it should be possible to give real values to the A/D counts. I'm working out the calibration process and when this is finished, I'll make up a Web page.
