Green Bank Solar Radio Burst Spectrometer
Background-Subtracted High Frequency Hourly Dynamic Spectra: 2009 02 18
Polarizations A and B are arranged vertically in separate images.
The frequency range is about 100 (bottom) to 1300 MHz (top of each
panel) but a filter should block emission below 300 MHz.
Dropouts occur if the 45-foot antenna loses tracking.
Vertical ticks every 10 minutes, horizontal ticks at 100 MHz intervals.
Vertical white lines (dotted lines on light curve) indicate local sunrise and sunset (to within 2 minutes).
