Auroral regions having luminosity fluctuations in the range of a few Hertz up to ~100 Hertz are termed regions of ``flickering aurora''. Rocket observations of particle precipitation associated with flickering aurora show bursts of field-aligned electron flows (``Field-Aligned Bursts''), occurring at the same frequency as the flickering. While it appears that field-aligned bursts are most often observed in breakup aurora, the mechanism responsible for their generation is not well understood. Ground-based observations of extended periods of flickering were acquired in Kaktovik, Alaska during the winter of 2000. The data was initally acquired on video tape and then subsequently digitized for analysis, which then provides spatial and temporal characteristics of flickering patches at predominant frequencies. Assuming, as the in-situ data suggests, that the flickering results from field-aligned bursts, we treat the image data as a proxy for the field-aligned bursts and interpret our results in that context.
