Green Bank Solar Radio Burst Spectrometer
Background-Subtracted Hourly Dynamic Spectra: 2004 02 29
The frequency range is typically 20 (bottom) to almost 70 MHz (top of each panel).
These data have had narrowband interference as well as background
subtraction performed, so the galactic
background at low frequencies is no longer present but residuals of
the broad band of interference at 20-24 MHz are usually prominent. Lightning
can show up as broadband but finite frequency width features.
On days of prominent long-lasting broadband emission subtraction is carried
out using an earlier "clean" day and some artefacts may result.
