More Images and Station Information


The Redwood City near real-time images are created using my new WinSDR datalogger program. The image on my main web page shows the North-South channel of a strong motion FBA-23 accelerometer sensor. The channel ID is LCNH. For more information and a photo of this sensor see this page. The image shows the last 12 hours worth of data from this sensor. 

The images above shows the last 24 hours worth of data from local and remote sensors I am monitoring and other PSN stations around the world.
