Before we go to the near real time data page I have provided a few plots to familiarize you with what you might see in the data. In all plots that you will see including near real time data the vertical grid spacing is one per second. This will give you some idea as to time verses the signal recorded. The receiver used is a modified version of the latest Elfrad circuit and is capable of receiving signals from DC Hz. to 30 Hz. Heavy filtering blocks all signals occurring above 30 Hz. Currently I use a scan rate of 40 samples per second with a Dataq Data Acquisition module which resolves signals from DC to 20 Hz.
When you reach the near real time page please note the page is Meta Tagged to tell your browser to automatically refresh so you will be able to see new data as it is uploaded every 60 seconds. If you do not see a new plot and your browser does not refresh automatically then it is not configured for Meta Tags. Manually refreshing your browser every 60 seconds or so will allow you to see the next uploaded plot.
One more note: Periodically you will notice a sinewave like looking pattern. An up and down motion in the plots. This is due to vehicles passing through the Earth's local DC Magnetic field 200 feet away from the Induction Magnetometer. This problem will be rectified once I relocate.
This first plot is of a Meteor entry in to the Atmosphere. I was fortunate to be able to not only see the burn visually but to simultaneously watch the computer as it recorded the entry. Since that time a few more have been recorded. Space debris entries have a signature all their own.
This next plot is of a signal that occurs at a frequency of 2.8 Hz. to 2.9 Hz. It appears at different times of the day and days may pass until it is observed again. This signal appears to be a pulse of sorts and I have seen a spacing between pulses of 6, 12 and 24 seconds. The signal can last from any where from 20 minutes up to 11 hours. It is not of local origin as it has also been observed in North Carolina. Fading of the signal has also been noticed.
Here is another you may observe that appears to occur lower in frequency. There is no set time it occurs but it is a constant signal and again appears not to be local or identifiable.
This final plot is of another interesting signal. It usually almost always occurs for a brief time following the 2.8 Hz. to 2.9 Hz. signal.
This plot demonstrates what the first Schumann Resonance and the lightning transients that maintain Schumann look like using my current data acquisition module and software.
This final plot shows a strong first resonance recorded July 14th. 2003
