Search Coil Spectra 1996/08/23
Below is a plot of a ~7 minute stretch of the 21" search coil
spectra taken over the polar cap. Whistler wave emissions can be seen from
~10:28 UT to ~10:31 UT in the ~2 kHz to >16 kHz frequency band. A strong
burst is seen at ~10:30. The SFA (swept frequency analyzer) shows the VLF
emissions as high as ~200 kHZ at ~10:30 UT. The 9 kHz and 14 kHz lines
(18 kHz folded about 16 kHz) are the fluxgate drivers that are seen
because the booms are still stowed.
