Daily chart showing data from Flamsteed VLF receiver (see this report for details).

The red line shows data from the Flamsteed VLF receiver, which is tuned to the Ramsloh VLF transmitter. The blue line shows NOAA GOES X-ray data.

GOES X-Ray Flux Data

All data is provided by the NOAA Space Weather Prediction Centre.

The GOES X-ray flux plot contains 1 minute averages of solar X-rays in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary GOES X-ray satellite is shown. Some data dropouts will occur during satellite eclipses.

GOES X-Ray Flux (5-minute data):

The GOES X-ray Flux plot contains 5 minute averages of solar X-ray output in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from the SWPC Primary and Secondary GOES X-ray satellites are shown. Some data dropouts from the Primary satellite will occur during satellite eclipses.
