A comparison of magnetometer data from Ottawa with WAL LOS velocity. a The dynamic spectrum of the X component data from the Ottawa magnetometer for the interval 0604 to 0611 UT on 1 August 2007. The contours represent different levels of power with the lighter colors the higher power. b The high time resolution estimates of the LOS velocity from WAL for the same period. c The shorter interval is marked by vertical dashed lines.
