The images on this page are snapshots of the last 2 and 24 hours of data the ANF is currently receiving from okssen stations.
Waveform data is yellow with a dark blue background. A black background represents zero data return. The most recent data is on the right-hand side, with the edge of the right-hand side of the image being the current time.
The identifying code (on the left-hand side) is in the format NN_STA_CHA where NN is the operating network (i.e. the Transportable Array (TA), a regional network like CalTech (CI) or the USNSN(US)), STA is the station code, and CHA is the channel code used to identify a particular data stream from the station (e.g. HHZ is a broadband, High sample rate, High gain, Vertical component data stream).
