How's the Weather?
[An N6ECT-2 Experiment]
Flying Snail Weather and Seismic Activity

Click above image for large picture. Top portion is local weather and bottom portion is concurrent seismic activity; UTC time noted on left. GPS date, UTC, PDT time is located in the lower left corner of above image.

22 MPH Wind Noise

Note: Some Large traces reflect wind noise on heliplots and the above image shows what happens to a sensor signal when a 22 MPH wind hits the seismic shed. This problem is being corrected and a Weather Page will be added soon.

PGandE SPIKE

Note: Every morning, +/- 6 AM - Pacific Gas & Electric SPIKE on seismic sensors, despite in-line UPS APC power supplies.

I am working on a better electrical filtering system and will be moving to alternative power in the future.

What Helicopters flying near the seismic shed look like on the sensors.

Note: Helicopters flying near Seismic Shed create traces on seismic sensor heliplots.
