Not yet. After some software alterations I've tried down to 1uHz bandwidth (about 10 days integration) but not the slightest trace. Noise floor down there is around 0.003 fT. Sferic blanker is working well. Tried integrating separately day and night, E and H and combined and separate, blanking out the noisy periods, etc in various combinations. It's been a slow job even with a quick computer - each run takes a long time to pass all the signal through. Disappointing, I thought we might have seen at least a hint of signal. I wonder if perhaps the signal is a bit too close to a cavity mode and dispersion effects are messing up the phase. This is uncharted territory. LWPC doesn't give a solution down here so can't use that as a guide. Or maybe there's just not enough ERP. Well, I haven't given up yet but for now I've run out of ideas. -- Paul Nicholson --
