A bright bolide appeared over the Netherlands on the evening of 2003, February 19. Infrasound generated by this bolide was detected at two nearby infrasound arrays as two distinct events. The origins of the infrasonic signals were located in the stratosphere at heights of 30 and 57 km. The results were obtained independently of visual observations of the bolide but confirm the reported time of occurrence. The ability to distinguish between a moving and static source is crucial for the application of infrasound as a monitoring technique. This study also illustrates the dependence of the infrasound technique on signal coherency, inter‐array distance and atmospheric knowledge.
