AB: The unusual level of flare and CME activity observed in late October 2003 also produced particularly remarkable coronal pulse waves (also called "EIT waves.") Among these events is an EIT wave which appears to travel a complicated trajectory across the solar disk over a period of roughly 2.5 hours, remaining coherent and identifiable throughout the time period. The wave front travels through varied topologies, including a filament channel and an active region. We present results describing the wave dynamics, and discuss how this observation both verifies and contradicts the expected behavior of coronal pulse waves.
