We report observations of two negative polarity gigantic jets sufficiently near very high‐frequency (VHF) lightning
mapping networks that the associated lightning characteristics and charge transfer could be investigated. In both cases
the gigantic jet‐producing flash began as ordinary intracloud lightning with upper level channels attempting to exit the cloud, and then produced the upward gigantic jet. Neither flash had developed channels to ground, confirming that the major charge transfer during gigantic jets occurred
between the cloud and ionosphere. The leader progression of one event was detected at altitudes above 20 km, demonstrating the possibility of detecting and tracking the propagation of negative jets above the cloud with VHF techniques.
